Description
Technical Field
The invention relates to the field of headphones, in particular to a headphone with an external sound physical transmission mode.
Background
The earphone is a wearing device for converting electric signals into sound waves by using a loudspeaker, and the wearing device generally needs to keep the air tightness in an ear canal and isolate external sounds so as to improve the experience of a user. However, excessive isolation of external sounds, especially active noise reduction or ambient noise reduction, which is popular in recent years, will greatly reduce the perception of the surrounding environment, causing a degree of safety concern.
At present, when some earphone manufacturers develop new earphone models, safety problems are considered, and a through mode for enhancing external sound is designed. For example, the active noise reduction is turned off, or the external microphone and the amplifier are used to send the external sound into the interior in a signal mode, and then the external sound is played in the interior. However, external sounds in these modes are easily distorted, or the power consumption of the battery is increased, which is disadvantageous for prolonging the service life of the earphone.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the earphone with the external sound physical permeation mode, which utilizes the conversion of a physical structure to naturally send the external sound into the auditory canal and can be converted into the permeation mode capable of hearing the external sound under the condition of wearing no change.
The technical scheme for achieving the purpose is as follows:
the invention provides an earphone with an external sound physical transmission mode, which comprises a loudspeaker module, a front sound cavity and a mode switching component. The speaker module has a speaker direction side for emitting a sound from the speaker direction side. The front sound cavity is coupled with the loudspeaker module from the loudspeaker direction side and comprises a sound guide tube for receiving and transmitting sound; at least one inner sound-transmitting duct is arranged on one wall of the sound guide tube. The mode switching component is arranged outside the pipe wall of the sound guide pipe and can rotate relative to the pipe wall, and the mode switching component is provided with at least one outer sound transmission pore canal penetrating through the mode switching component. When the front sound cavity and the mode switching component relatively rotate to the outer sound transmission pore canal to be communicated with the inner sound transmission pore canal, the sound guide pipe receives an external sound from the outside through the outer sound transmission pore canal and the inner sound transmission pore canal; when the front sound cavity and the mode switching component relatively rotate to the mode switching component block the inner sound transmission pore canal and the outside, the mode switching component blocks outside sound from entering the sound guide tube.
The earphone with the external sound physical transmission mode further comprises an internal magnetic unit and a magnetic induction module. The internal magnetic unit is disposed within the structure of the mode switching assembly. The magnetic induction module is coupled with the loudspeaker module. When the current sound cavity and the mode switching component relatively rotate to enable the magnetic induction module to be close to or far away from the internal magnetic unit, the magnetic induction module outputs one of a loudspeaker turn-off signal or a loudspeaker turn-on signal to the loudspeaker module.
Further, when the front sound cavity and the mode switching component relatively rotate to the outside sound transmission duct and are communicated with the inside sound transmission duct, the magnetic induction module outputs a loudspeaker turn-off signal; when the current sound cavity and the mode switching component relatively rotate to the mode switching component to obstruct the inner sound transmission pore canal and the outside, the magnetic induction module outputs a loudspeaker starting signal.
The mode switching assembly further comprises a tapered sound collecting cover structure communicated with the outside and the outer sound transmission pore canal. Or, the mode switching assembly further comprises an ear wing hook structure, wherein the ear wing hook structure is provided with a tapered sound collecting cover structure communicated with the outside and the outer sound transmission pore canal.
And the sound transmission extending direction of the outer sound transmission duct and the sound transmission extending direction of the sound guide tube form an included angle which is smaller than 90 degrees, so that an external sound enters the outer sound transmission duct in the forward direction.
The earphone with the external sound physical permeation mode further comprises a back sound cavity, a thin electromagnet module and an external magnetic unit. The rear sound cavity is connected with the front sound cavity, and the loudspeaker module is positioned between the front sound cavity and the rear sound cavity. The thin electromagnet module is arranged on the surface of the rear sound cavity in the rotating direction of the mode switching assembly. The external magnetic unit is fixedly arranged on the surface of the mode switching assembly and is magnetically coupled with the thin electromagnet module. When the thin electromagnet module receives a control signal, the thin electromagnet module reverses the magnetic pole direction, the magnetic field drives the external magnetic unit to displace, and the mode switching assembly is driven to rotate.
The invention also provides another embodiment of the earphone with the external sound physical transmission mode, which comprises a loudspeaker module, a front sound cavity and a mode switching component. The speaker module has a speaker direction side for emitting a sound from the speaker direction side. The front sound cavity is coupled with the loudspeaker module from the side of the loudspeaker direction, and the front sound cavity further comprises a sound guide tube for receiving and transmitting sound, wherein the tube wall of the sound guide tube is provided with an inner sound transmission channel through tube wall. The mode switching component is movably arranged on the sound guide tube in a penetrating way. The mode switching assembly is further provided with an outer sound transmission pore canal which is formed inside the mode switching assembly and is provided with an outer port and an inner port, wherein the outer port is communicated with the outside, and the inner port is used for being communicated with the sound guide tube. When the mode switching component relatively moves to the inner port to be communicated with the sound guide pipe, the sound guide pipe receives an external sound from the outside through the external sound transmission pore canal and the internal sound transmission pore canal; when the mode switching component relatively moves to the pipe wall to block the inner opening, the pipe wall blocks external sound from entering the sound guide pipe.
The mode switching assembly further comprises a tapered sound collecting cover structure communicated with the outside and the outer sound transmission pore canal.
In addition, the earphone with external sound physical through mode of the embodiment further comprises a micro pressing unit coupled with the speaker module and used for abutting against the mode switching assembly, when the mode switching assembly and the sound guide tube relatively move to enable the internal port to be communicated with the sound guide tube, the micro pressing unit is far away from the mode switching assembly and outputs a loudspeaker turn-off signal to the speaker module.
The earphone with the external sound physical through mode has the beneficial effects that:
in summary, according to the earphone with the external sound physical transmission mode provided by the invention, external sound can enter the sound guide tube through the mutual transmission of the external sound transmission hole channel in the mode switching component and the internal sound transmission hole channel in the sound guide tube. And the relative structure of the mode switching component and the sound guide tube can be changed by rotating or pushing, so that the outside sound permeability can be changed by simple switching. The main effect is to pass through and keep the original sound of the external sound into the earphone without extra power consumption. And the relative structure is changed, and the micro sensor in the earphone is used for triggering the opening or closing of the musical sound of the loudspeaker, so that the definition of external sound is improved. Finally, the signal can be converted into magnetic force by utilizing a simple electromagnet principle to change the relative structure, so that the effect of automatically converting the external sound transmission mode is achieved.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.
The usual way of using headphones is hereinafter referred to as a musical tone mode, in which the wearer mainly listens to sounds emitted by the speaker module; the manner in which ambient sounds outside the headset are received into the headset is referred to as a pass-through mode, in which the wearer primarily listens to ambient sounds.

The earphone W1 with the external sound physical transmission mode provided in this embodiment includes a speaker module 1, a front sound cavity 2 and a mode switching component 3. The speaker module 1 has a speaker direction side for emitting a sound from the speaker direction side. The front sound cavity 2 is coupled to the speaker module 1 from the speaker direction side, and the front sound cavity 2 further includes a sound guide tube 21 for receiving and guiding sound; at least one inner sound-transmitting duct 20 is provided on one wall of the sound guide tube 21 to penetrate the wall. The mode switching component 3 is disposed outside the wall of the sound guiding tube 21 and can rotate relative to the wall, and the mode switching component 3 has at least one outer sound transmitting channel 30 penetrating the mode switching component 3. When the front sound cavity 2 and the mode switching component 3 relatively rotate to the outer sound transmission channel 30 and are communicated with the inner sound transmission channel 20, the sound guide tube 21 receives an external sound from the outside through the outer sound transmission channel 30 and the inner sound transmission channel 20, as shown in fig. 4 to 5; when the front sound cavity 2 and the mode switching component 3 relatively rotate until the mode switching component 3 blocks the inner sound transmission duct 20 from the outside, the mode switching component 3 blocks the outside sound from entering the sound guide tube 21, as shown in fig. 6.
The earphone W1 in the physical transmission mode of external sound further comprises a rear sound cavity 4 and an earplug 5. The earplug 5 is soft and is intended to be inserted into the ear canal. The speaker module 1 includes a diaphragm and a circuit control assembly, receives electrical signals to convert them into sound waves, and emits the sound in the direction of the ear canal and the ear plug 5. The loudspeaker module 1 is generally defined as a loudspeaker module, wherein a vibrating diaphragm is taken as a central line, a sound producing side is taken as a front sound cavity 2, and a back sound cavity 4 is taken as a back sound cavity. The back tone chamber 4 is sealingly engaged with the front tone chamber 2 such that the speaker module 1 is located between the front tone chamber 2 and the back tone chamber 4 and protected within the chamber.
In this embodiment, the mode switching assembly 3 is annular and is sleeved outside the front sound cavity 2, the mode switching assembly 3 has four outer sound transmission channels 30 (as shown in fig. 7), and the wall of the sound guide tube 21 has four inner sound transmission channels 20. The four outer sound-transmitting channels 30 and the four inner sound-transmitting channels 20 are located substantially on the same plane, and each outer sound-transmitting channel 30 corresponds to at least one inner sound-transmitting channel 20. The rotation mode switching assembly 3 enables the outer sound transmission duct 30 and the inner sound transmission duct 20 to be overlapped and air to circulate, and at this time, external sound can enter the sound guide tube 21 through the air medium, as shown in fig. 5. The rotation mode switching assembly 3 makes the outer sound transmission duct 30 and the inner sound transmission duct 20 staggered and air does not circulate, and at this time, external sound entering the outer sound transmission duct 30 is blocked by the wall of the sound guide tube 21, as shown in fig. 6.
In this embodiment, the outer surface of the front sound cavity 2 is provided with a limiting hook 27 to limit the rotation angle of the mode switching assembly 3. The rotation angle is between 20 degrees and 60 degrees. For example, after rotating 45 degrees clockwise, the outer sound-transmitting duct 30 and the inner sound-transmitting duct 20 are blocked by the limiting hooks 27, and are completely overlapped; the outer sound-transmitting duct 30 and the inner sound-transmitting duct 20 are completely staggered at the moment when the clock is reversed by 45 degrees and then blocked by the limiting hook 27.
By means of physical structure switching, a user can hear external environment original sound without extra power consumption. And the control is simple and intuitive for a user, and the switching can be completed without visual assistance.
The sound transmission extending direction E of the outer sound transmission duct 30 and the sound transmission extending direction M of the sound guide tube 21 form an included angle A, and the included angle A is smaller than 90 degrees, so that an external sound enters the outer sound transmission duct 30 in a forward direction. The volume and definition of external sound are increased.
The earphone W1 with the external sound physical transmission mode further includes an internal magnetic unit 63 and a magnetic induction module 61. The internal magnetic unit 63 is provided within the structure of the mode switching assembly 3. The magnetic induction module 61 is coupled to the speaker module 1. When the front sound cavity 2 and the mode switching assembly 3 relatively rotate to make the magnetic sensing module 61 approach to or separate from the internal magnetic unit 63, the magnetic sensing module 61 outputs one of a speaker turn-off signal or a speaker turn-on signal to the speaker module 1. The speaker off signal can prevent the electric signal from being converted into sound wave completely or reduce the volume; the speaker-on signal is converted into sound wave by the corresponding recovery electric signal or the volume is recovered.
When the front sound cavity 2 and the mode switching component 3 relatively rotate until the outer sound transmission pore channel 30 is communicated with the inner sound transmission pore channel 20, the magnetic induction module 61 outputs a loudspeaker turn-off signal; when the front sound cavity 2 and the mode switching component 3 relatively rotate until the mode switching component 3 blocks the inner sound transmission duct 20 from the outside, the magnetic sensing module 61 outputs a speaker opening signal. In this embodiment, the front sound cavity 2 and the mode switching assembly 3 relatively rotate until the outer sound transmission channel 30 is communicated with the inner sound transmission channel 20, and the magnetic sensing module 61 is also close to the inner magnetic unit 63, so that the magnetic sensing module 61 outputs a speaker turn-off signal. The internal magnetic unit 63 may be an NdFeB magnet that consumes no power, and the magnetic induction module 61 may be a hall sensor that consumes very little power. Therefore, under the configuration of extremely low power consumption, the original musical sound generated by the loudspeaker module 1 can be simultaneously turned off or reduced in the transparent mode, so that the external sound is clearer.
The earphone W1 with the external sound physical transmission mode further includes a thin electromagnet module 74 and an external magnetic unit 73. The thin electromagnet module 74 is disposed on the surface of the rear sound chamber 4 in the rotation direction of the mode switching assembly 3. The external magnetic unit 73 is fixed on the surface of the mode switching assembly 3 and magnetically coupled to the thin electromagnet module 74, as shown in fig. 7. When the thin electromagnet module 74 receives a control signal, the thin electromagnet module 74 reverses the magnetic pole direction, and the magnetic field drives the external magnetic unit 73 to displace and drives the mode switching assembly 3 to rotate. The external magnetic unit 73 may be a NdFeB magnet as well. For example, the S end of the external magnetic unit 73 is magnetically coupled with the N pole of the upper end of the thin electromagnet module 74; the thin electromagnet module 74 receives a control signal to enable the upper end and the lower end of the thin electromagnet module 74 to have magnetic poles reversed, the S end of the external magnetic unit 73 is repelled by the S pole at the upper end of the thin electromagnet module 74 and is attracted to the N pole at the lower end, and then the mode switching assembly 3 is driven to rotate. Of course, when receiving another control signal, the upper and lower poles of the thin electromagnet module 74 can be reversed again, so as to drive the mode switching assembly 3 to rotate back.
In this embodiment, the mode switching assembly 3 further includes a sound collecting cover structure 38 in communication with the outside and the outer sound transmission duct 30. The sound collecting housing structure 38 may be a tapered structure, mainly to increase the received external sound.
The second embodiment is shown in fig. 10 to 17. FIGS. 10 to 11 are perspective views and exploded views of an earphone according to a second embodiment of the present invention; fig. 12 and 13 are schematic diagrams and cross-sectional views of an earphone in a through mode in the second embodiment; FIG. 14 is a cross-sectional view of the headset in a pass-through mode along the HH line as in FIG. 12; fig. 15 and 16 are a schematic view and a sectional view of an earphone in a tone mode in the second embodiment; fig. 17 is a cross-sectional view of the earphone in the musical tone mode along line II as in fig. 15.
The structure and components not mentioned in the second embodiment are in principle the same as in the first embodiment. The second embodiment is different from the first embodiment in that it will be described in the following paragraphs.
In the earphone W2 with the external sound physical transmission mode of the second embodiment, the mode switching assembly 3 further includes an ear wing hook structure 39, and a sound collecting cover structure in the ear wing hook structure 39 communicates with the external and the external sound transmission duct 30. The ear wing hook 39 is fastened to the auricle and concha of the user, so that the earphone W2 with the external sound physical transmission mode is more firmly attached to the ear of the user. The ear wing hook structure 39 also serves as a sound collecting cover structure, and the received external sound definition is further enhanced. Therefore, only one outer sound transmission duct 30 and a corresponding one inner sound transmission duct 20 may be provided in the earphone W2 having the external sound physical transmission mode.
Since the ear wing hook structure 39 of the second embodiment makes the mode switching assembly 3 difficult to rotate, in the second embodiment, the mode switching assembly 3 is fixed, and the rotating rear sound cavity 4 is linked with the front sound cavity 2, so that the outer sound transmission duct 30 and the inner sound transmission duct 20 are communicated or staggered. The outer sound-transmitting duct 30 and the inner sound-transmitting duct 20 are overlapped and air circulates by rotating, and at this time, external sound can enter the sound guide tube 21 through the air medium, as shown in fig. 12 to 14. The outer sound-transmitting duct 30 and the inner sound-transmitting duct 20 are staggered by rotation and air is not circulated, and at this time, external sound entering the outer sound-transmitting duct 30 is blocked by the wall of the sound guide tube 21, as shown in fig. 7.
In this embodiment, a limiting hook (not shown) is also designed to limit the rotation angle of the mode switching component 3. The rotation angle may be between 10 degrees and 60 degrees, for example, in the present embodiment, the rear sound cavity 4 (earphone line) of fig. 12 and the rear sound cavity 4 (earphone line) of fig. 15 are different by 43 degrees.
In this embodiment, the earphone W2 with the external sound physical transmission mode may further include a thin electromagnet module and an external magnetic unit (not shown), and its operation mode, means and purpose are the same as those of the first embodiment.
As shown in fig. 12 to 14, in the through mode, when the magnetic sensing module 61 is far away from the internal magnetic unit 63, the magnetic sensing module 61 outputs a speaker turn-off signal; as shown in fig. 15 to 17, when the magnetic sensing module 61 approaches the internal magnetic unit 63 in the musical tone mode, the magnetic sensing module 61 outputs a speaker turn-on signal. Means and purposes of the speaker off signal and the speaker on signal are the same as those of the foregoing embodiments.
Please refer to fig. 18-28. Fig. 18 is an oblique view of an earphone in a tone mode in the third embodiment of the present invention; FIG. 19 is an oblique view of the headset in a pass-through mode; FIG. 20 is an exploded view of the headset; fig. 21 is a front view of the earphone in a musical tone mode; fig. 22 is a cross-sectional view of the earphone in the tone mode along the CC tangent line; fig. 23 is a side view of the earphone in a musical tone mode; FIG. 24 is a cross-sectional view of the earphone in a tone mode along the DD cut line; FIG. 25 is a front view of the headset in a pass-through mode; FIG. 26 is a cross-sectional view of the earphone in a pass-through mode along line EE; FIG. 27 is a side view of the earphone in a pass-through mode; fig. 28 is a cross-sectional view of the earphone in a pass-through mode along line FF.
In a third embodiment, the present invention further provides an earphone W3 having an external sound physical transmission mode, which includes a speaker module 1, a front sound cavity 2 and a mode switching component 3. The speaker module 1 is as in the previous embodiment. The front sound cavity 2 is coupled to the speaker module 1 from the speaker direction side, and the front sound cavity 2 further comprises a sound guiding tube 21 for receiving and guiding sound, wherein the wall of the sound guiding tube 21 has an inner sound transmitting channel 20. The mode switching component 3 is movably arranged on the sound guide tube 21 through the inner sound transmission hole channel 20. The mode switching assembly 3 further has an outer sound-transmitting duct 30 formed inside the mode switching assembly 3 and having an outer port 30E and an inner port 30I, the outer port 30E being in communication with the outside, the inner port 30I being for communication with the sound guide tube 21. When the mode switching assembly 3 relatively moves to the inner port 30I to communicate with the sound guiding tube 21, the sound guiding tube 21 receives an external sound from the outside through the external sound transmitting hole 30 and the internal sound transmitting hole 20, as shown in fig. 10; when the mode switching member 3 is relatively moved to the tube wall blocking inner port 30I, the tube wall blocks external sounds from entering the sound guide tube 21, as shown in fig. 21 to 24.
The biggest difference between the third embodiment and the first and second embodiments is that the rotation mode switching element 3 is changed to the displacement mode switching element 3, and the relative positions of the outer sound-transmitting duct 30 and the inner sound-transmitting duct 20 are changed from inside to outside to be interposed.
The mode switching member 3 in the third embodiment may be long cylindrical or long flat, and at least one end of the mode switching member 3 has an external port 30E communicating with the external sound-transmitting duct 30. The external port 30E may be an opening facing along the axis of the mode switching assembly 3 or a side facing opening at the end of the mode switching assembly 3. The mode switching assembly 3 may further comprise a tapered sound collecting cover structure 38 communicating with the outside and the outer sound transmission duct 30E.
The middle section of the mode switching assembly 3 has an internal port 30I communicating with the external sound-transmitting duct 30. The third embodiment has the inner port 30I open to the side of the mode switching member 3 to ensure that the inner port 30I faces the wall of the sound guiding tube 21 beside the inner sound-transmitting duct 20. When the mode switching member 3 is displaced outwardly so that the inner port 30I faces the wall of the sound guiding tube 21 beside the inner sound-transmitting duct 20, the inner port 30I is blocked by the wall, and the outer sound-transmitting duct 30 communicates with the outside but does not communicate with the sound guiding tube 21, forming a musical tone mode as shown in fig. 21 to 24; when the mode switching member 3 is displaced inward to make the inner port 30I go deep into the sound guiding tube 21, the outer sound transmitting duct 30 communicates with the outside and the sound guiding tube 21 at the same time, forming a through mode as shown in fig. 25 to 28.
In other embodiments, the inner sound-transmitting duct 20 can be a bent channel, such as type ㄣ. At this time, the inner port 30I is an opening facing the axis of the mode switching member 3, and when the mode switching member 3 is displaced inward and blocked by the wall of the inner sound-transmitting duct 20, the outer sound-transmitting duct 30 communicates with the outside but does not communicate with the sound guide tube 21, forming a musical tone mode; when the mode switching assembly 3 is displaced outwards to keep a gap with the wall of the inner sound transmission duct 20, the outer sound transmission duct 30 is communicated with the outside and the sound guide tube 21 at the same time, so that a transparent mode is formed.
In the earphone W3 with external sound physical through mode of the third embodiment, if the mode switching assembly 3 is large and still occupies the path in the sound guide tube during the music mode, the middle section of the mode switching assembly 3 may be notched or the music hole 35 may be formed. Whereby sound can still pass through the notch or tone hole 35 from the speaker module 1 to the ear canal in the tone mode.
The earphone W3 with the physical through mode of external sound further comprises a micro pressing unit 7 coupled to the speaker module 1 and used for abutting against the mode switching assembly 3, when the mode switching assembly 3 and the sound guiding tube 21 relatively move to enable the internal port 30I to be communicated with the sound guiding tube 21, the micro pressing unit 7 is far away from the mode switching assembly 3 and outputs a speaker off signal to the speaker module 1. Conversely, when the mode switching element 3 and the sound guide tube 21 relatively move to block the inner opening 30I by the wall of the sound guide tube 21, the micro pressing unit 7 abuts against the mode switching element 3 and outputs a speaker start signal to the speaker module 1. Means and purposes of the speaker off signal and the speaker on signal are the same as those of the foregoing embodiments.
In this embodiment, the earphone W3 with the external sound physical transmission mode may further include a thin electromagnet module and an external magnetic unit (not shown), where the thin electromagnet module and the mode switching assembly 3 are disposed outside the front sound cavity 2 in the same direction, and the external magnetic unit is disposed on the mode switching assembly 3 near the thin electromagnet module. When the thin electromagnet module receives the control signal to reverse the electrode, the external magnetic unit is pulled to the other magnetic pole, and the mode switching assembly 3 is pulled to move.
In summary, according to the earphone with the external sound physical transmission mode provided by the embodiment of the invention, external sound can enter the sound guide tube by means of mutual transmission of the external sound transmission hole in the mode switching component and the internal sound transmission hole in the sound guide tube. And the relative structure of the mode switching component and the sound guide tube is changed by rotation or pushing displacement, so that the external sound permeability can be changed by simple switching. And the relative structure is changed, and the micro sensor in the earphone is used for triggering the opening or closing of the musical sound of the loudspeaker, so that the definition of external sound is improved. Finally, the signal can be converted into magnetic force by utilizing a simple electromagnet principle to change the relative structure, so that the effect of automatically converting the external sound transmission mode is achieved. Compared with the prior art, the invention adopts a physical structure, and the main effect difference is that external sound is penetrated and the external sound source sound is kept in the earphone under the condition of no extra power consumption.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
