In this embodiment, the housing 10 includes a front shell 11 and a rear shell 12, and the front shell 11 and the rear shell 12 enclose to form an accommodating cavity. The earphone further comprises an electric control board 13 and a loudspeaker 14, the electric control board 13 and the loudspeaker 14 are both accommodated in an accommodating cavity formed by enclosing the front shell 11 and the rear shell 12, the main controller 30 and the reminding circuit 40 can be arranged on the electric control board 13, and the electric control board 13 and the loudspeaker 14 can be electrically connected through a flexible circuit board or a lead. The first sensor 20 is disposed near the rear case 12 of the housing 10, and the first sensor 20 may be disposed on the electric control board 13 and attached to the rear case 12. Alternatively, the first sensor 20 is disposed on the rear case 12 and fixed on the rear case 12 by a connecting member made of adhesive material such as glue, double-sided tape 18, solid glue, etc. In some embodiments, a recess may also be provided in the rear housing 12 to receive the first sensor 20 within the recess of the rear housing 12. When the first sensor 20 is disposed on the rear case 12, the first sensor 20 is electrically connected to the electronic control board 13 through the flexible circuit board 15 or a wire.

In some embodiments, the earphone further comprises a bracket 16, the bracket 16 is disposed in the housing for fixedly mounting the speaker 14, and the flexible circuit board 17 is fixedly mounted for connecting the second sensor 60, the bracket 16 is disposed on a side of the housing near the front shell 11, the bracket 16 has a receiving cavity, and the speaker 14 is received in the receiving cavity of the bracket 16, so that the relative movement between the speaker 14 and the earphone can be prevented. The second sensor 60 is disposed on the front housing 11 and fixed on the bracket 13 by a connecting member made of adhesive material such as glue, double-sided tape 19, solid glue, etc.

The main controller 30 may be a microcontroller such as a DSP and a single chip, or a control chip such as a bluetooth chip that can implement a wireless function, and this embodiment is preferably implemented by using a bluetooth chip. The main controller 30 is a control center of the headset, connects various parts of the whole headset by using various interfaces and lines, and performs various functions of the headset and processes data by operating or executing software programs and/or modules stored in the memory and calling data stored in the memory, thereby integrally monitoring the headset. The main controller 30 may include one or more processing units; preferably, the main controller 30 may integrate the modem main controller 30 to handle wireless communication. It is to be understood that the modem host controller 30 described above may not be integrated into the host controller 30.

In one embodiment, the first sensor 20 is any one of a capacitive sensor, a bio-radio frequency sensor, and an optical identification sensor. Of course, in other embodiments, the first sensor 20 may also be other sensors capable of recognizing the characteristics of the user, and is not limited herein. The following embodiments of the present invention will be described by taking the first sensor 20 as a capacitive sensor as an example. The first sensor 20 is used to detect whether the headset is matched with a human finger, for example, whether the left headset is held by the left hand and/or the right headset is held by the right hand.

It will be appreciated that the user holds the headset with a different contact area between the left or right hand and the headset, and different vital signs, such as fingerprints, etc., for the left hand fingers and the right hand fingers. According to the difference between the left hand and the right hand, whether the current earphone is held by the left hand or the right hand can be identified.

Specifically, when the user picks up the earphone, the hand and the earphone generate a plate capacitance effect, a capacitor is formed between the earphone and the human body, and a corresponding capacitance value is generated between the hand and the earphone. When the user picks up the headset, the capacitive touch sensor at the headset housing 10 detects an increase in capacitance between itself and the human finger according to the relationship of the capacitor: c = epsilon S/L (1)

Wherein epsilon is a dielectric constant, S is an area of contact between two fingers and the housing 10 in a capacitor formed by the earphone and the human body, and L is a distance between the human body and the sensor, as can be seen from the formula (1), the capacity of the capacitor is in direct proportion to the dielectric constant of the medium, in direct proportion to the areas of the two polar plates, and in inverse proportion to the distance between the two polar plates.

In addition, when a capacitor is charged with Q charge, the two plates of the capacitor will form a certain voltage, and the following relationship is given:

C＝Q/V (2)

wherein Q is the electric charge quantity charged by the capacitor formed by the human body and the sensor, namely the charge, the charge is fixed in one capacitor, and the sensor is fixed in the shell, so the distance between the finger and the sensor is fixed, when the human body holds the earphone by the finger, along with the difference of the holding modes of the left hand and the right hand, when the area of the finger contacted with the shell 10 generates corresponding change, the formula (1) can know that different capacitance C is necessarily formed, and the formula (2) further knows that the change of V can be generated due to the change of the capacitance C. In this way, the capacitive sensor senses whether the headset is held by the left hand or the right hand by detecting a change in capacitance formed between the headset and the human body, and generates a corresponding first sensing detection signal and transmits the first sensing detection signal to the main controller 30.

It will be appreciated that when the user wears the headset, the left headset is typically held in the left hand and fed to the left ear, and the right headset is typically held in the right hand and fed to the right ear. When the user uses the capacitance type capacitance sensing device for the first time, corresponding fingerprint or capacitance type sensing detection signals can be recorded to form a preset reference signal, and the preset reference signal can be a range of capacitance values. The value range of the main controller 30 in response to the finger grip corresponding to the first sensing detection signal can be adjusted by software algorithm programming and/or a hardware circuit in the main controller 30 according to actual application, so as to adjust the sensitivity of the headset to the left and right hand grip. In some embodiments, the left hand sensing detection signal and the right hand sensing detection signal may be simultaneously recorded in one earphone, and the recorded left hand sensing detection signal may be used as the first preset reference signal and the right hand sensing detection signal may be used as the second preset reference signal. So set up, make when left earphone is held by the left hand, the first response detected signal that first sensor 20 sensed this moment matches with left hand response detected signal. When the left earphone is held by the right hand, the first sensing signal sensed by the first sensor 20 is matched with the right sensing signal. When the first sensing detection signal is matched with the right sensing detection signal, the left earphone is held by the right hand. Similarly, when the right earphone is held by the right hand, the first sensing detection signal sensed by the first sensor 20 matches the right hand sensing detection signal, and when the right earphone is held by the left hand, the first sensing detection signal sensed by the first sensor 20 matches the left hand sensing detection signal.

The main controller 30 receives the first sensing detection signal as an analog signal, the main controller 30 may further convert the analog signal into a digital signal through an analog-to-digital conversion module integrated in the main controller 30, and compare and analyze the electrical signal converted into the digital signal through a software algorithm program and/or a hardware circuit module integrated in the main controller 30, so as to determine whether the headset is held by the left hand or the right hand, when the left headset is held by the right hand and/or the right headset is held by the left hand, it is determined that the fingers are not matched with the headset at this time, and a warning control signal is output. The reminding circuit 40 sends out reminding information to the user according to the reminding control signal so as to remind the user to exchange the held earphones, or remind the user to wear the right earphone by using the left hand and/or wear the left earphone by using the right hand. Compare in detecting the earphone again after the earphone is worn, earphone about automatic identification can be in advance in this embodiment, is favorable to preventing that the earphone from wearing to the contrary, reduces the latency of detecting left and right ears again after the earphone is worn simultaneously.

The earphone of the invention is provided with the first sensor 20 close to the earphone shell 10, detects the position relation between the human body finger and the first sensor 20 arranged on the shell 10, generates the first induction detection signal and outputs the first induction detection signal to the main controller 30, so that when the main controller 30 determines that the human body finger is not matched with the earphone according to the first induction detection signal and the preset reference signal, the main controller outputs a reminding control signal to the reminding circuit 40, works when receiving the reminding control signal and sends out reminding information to remind a user, prevent the audio-visual effect of the user from being influenced by wrong wearing of the left earphone and the right earphone, or prevent the user from discomfort caused by wrong wearing of the ears for a long time.

Referring to fig. 1 and 2, in an embodiment, the headset further includes an audio processing circuit 50, and the audio processing circuit 50 is electrically connected to the main controller 30;

the main controller 30 is further configured to trigger the audio processing circuit 50 to switch from the low power consumption state to the standby state when it is determined that the human body is set in the earphone according to the first sensing detection signal and the preset reference signal.

In this embodiment, the audio processing circuit 50 may be implemented by an audio codec IC, and the main controller 30 outputs the received audio signal to the audio processing circuit 50 to implement signal processing such as decoding and amplification of the audio signal, and then outputs the audio signal to the speaker 14 to implement output of the audio signal. The main controller 30 and the audio processing circuit 50 can be communicatively connected through an I2S interface.

It is understood that the earphone generally has a low power consumption state (deep sleep), an operating state and a standby state (sleep state), in the low power consumption state, only a small part of the functional modules are maintained to operate, for example, only the enable function is reserved, in the standby state, the state of preparation for operation is entered, and in the operating state, the processes such as scanning can be performed. When the human body finger is matched with the earphone, the fact that the user needs to use the earphone is indicated, the earphone is not worn well at the moment, the earphone can be controlled to be converted from the dormant state to the standby state at the moment, preparation for working is made in advance, and the user can rapidly enter the working state after wearing the earphone, and audio signals are played. By the arrangement, the response speed of the earphone can be improved under the condition of further saving the power consumption of the earphone. In addition, in some embodiments, it may also be detected that the user continues to hold the headset and does not wear the headset after detecting that the user holds the headset, for example, after 20s, that is, the user only holds the headset and does not wear the headset at this time, and the main controller 30 may control the audio processing circuit 50 to return to the low power consumption state from the standby state, so as to further reduce the power consumption of the headset and improve the intelligent control capability of the headset.

Referring to fig. 1 and 2, in an embodiment, the housing 10 includes a rear case 12 and a front case 11 covering the rear case 12;

the first sensor 20 is disposed proximate the rear housing 12;

the earphone further comprises:

a second sensor 60 disposed adjacent to the front case 11 and electrically connected to the main controller 30;

the second sensor 60 is configured to detect a position relationship between the human ear and the second sensor 60, and generate a second sensing detection signal.

In this embodiment, the second sensor 60 is disposed near the front housing 11, and the first sensor 20 may be disposed on the bracket 16 and attached to the front housing 11. Alternatively, the second sensor 60 is disposed on the front case 11 and fixed on the front case 11 by a connecting member made of adhesive material such as glue, double-sided tape, solid glue, etc. When the second sensor 60 is disposed on the bracket 16 or the front shell 11, the second sensor 60 is electrically connected to the electronic control board 13 through a flexible circuit board or a wire.

The second sensor 60 is used to detect whether the user wears the headset, and when the user uses the headset to listen to music, make a call or receive a call, the second sensor senses whether the headset is close to the ear of the human body through the distance sensing device. The second sensor 60 may be a distance sensing device that can sense a distance, such as a capacitance sensor, an infrared detection sensor, or the like. The infrared detection sensor and the capacitance approach detection sensor can be used for detecting whether the wireless earphone is close to the human ear or not, and the two approach detection sensors are used for detecting the distance from the wireless earphone to the human ear. When the infrared detection sensor is adopted for realization, the infrared detection sensor comprises an infrared emitting diode and a photosensitive receiving device, and the intensity of reflected infrared light can be adjusted by adjusting emitted current inside under the same distance. In this application, different with sending the infrared light always through infrared emitting diode among the prior art, through PWM control in this application, make infrared emitting diode transmission infrared pulse light to can reduce infrared detection sensor's consumption, and also can adjust the intensity of the infrared pulse light of transmission through PWM, and then the intensity of the infrared light that is reflected back is adjusted, according to the intensity alright obtain the distance of wireless earphone apart from people's ear by the infrared light that is reflected back. When a capacitance sensor is used for realizing the function, when a human body approaches, the distance between the earphone and the human body is changed, namely the distance between two polar plates of the capacitor is changed, the electrostatics shows that the charging charge of the parallel plate capacitor is fixed in the capacitor, when the distance between the two polar plates of the capacitor is changed by the approach or the distance of the human body, and a delta d is changed, the formula (1) shows that a delta C change is inevitably generated, and the formula (2) further shows that a delta V change is generated due to the delta C change. In this way, the capacitance sensor senses a distance between the human body and the earphone by detecting a change in capacitance formed between the earphone and the human body, and converts the distance signal into a corresponding electrical signal and transmits the same to the main controller 30. When the human ear is sensed to approach or leave the second sensor 60, the distance signal is converted into a corresponding electrical signal and then output to the main controller 30, so that the main controller 30 outputs a corresponding control signal according to the distance signal corresponding to the electrical signal. For example, when the human ear is sensed to be close, a control signal is output to play music; when the human ears are sensed to be far away from the earphones, the control signals are output to stop operations such as music playing. When the user wears the headset and the fingers are removed, the first sensor 20 at the headset back shell 12 detects a decrease in capacitance; the second sensor 60 at the front shell 11 of the earphone, i.e. the ear plug, detects the increase in capacitance between itself and the skin of the human ear, and recognizes that it is normally worn.

Referring to fig. 1 and fig. 2, based on the above embodiment, further, the main controller 30 is further configured to trigger the audio processing circuit 50 to switch from the standby state to the operating state when it is determined that the earphone is in the wearing state according to the second sensing detection signal.

When the earphone is detected to be worn normally, the user needs to play music or make a call by using the earphone, and the user can rapidly enter a working state and play the audio signal after wearing the earphone. By the arrangement, the response speed of the earphone can be improved under the condition of further saving the power consumption of the earphone.

Referring to fig. 1 and 2, in one embodiment, the headset further includes a memory 70, and the memory 70 is electrically connected to the main controller 30;

the main controller 30 is further configured to output the voice reminding signal stored in the memory 70 to the audio processing circuit 50 when the earphone is determined to be in the wearing state according to the second sensing detection signal.

In this embodiment, the memory 70 may be an EEPROM (Electrically Erasable Programmable read only memory 70), and the memory 70 stores therein earphone information, such as earphone model and bluetooth pairing information. In the memory 70 of this embodiment, voice reminding information is further stored, for example, reminding information recorded by the user himself, or voice reminding information recorded into the earphone before factory shipment, specifically, "You wear the left earphone at present," or "You are currently doing firm doing the left ear," and the like, when it is determined that the earphone is in the wearing state according to the second sensing detection signal, the main controller 30 reads the voice reminding signal stored in the memory 70, and outputs the voice reminding signal to the audio processing circuit 50, so that the audio processing circuit 50 converts the reminding information (digital signal) into an analog signal that can be played by the speaker 14 to remind the user whether the earphone is worn correctly, thereby further preventing the left and right earphones from being worn incorrectly to affect the audiovisual effect of the user, or bringing discomfort to the ears of the user due to long-time miswear.

Referring to fig. 1 and 2, in an embodiment, the main controller 30 is further configured to control the audio processing circuit 50 to switch from the operating state to the standby state when the headset is determined to be in the unworn state according to the second sensing detection signal and when the human finger is determined to be matched with the headset according to the first sensing detection signal and the preset reference signal.

In this embodiment, when the user takes off the earphone, the first sensor 20 at the front shell 11 of the earphone detects an increase in capacitance and detects a touch of a finger of a human body; at the same time, the second sensor 60 at the ear plug detects the decrease in capacitance between itself and the skin of the human ear, identifying the state of being removed at this time. Therefore, when the detection signal is detected to determine that the earphone is in the unworn state and the human finger is matched with the earphone, it indicates that the user takes the earphone off at the moment, for example, a short music pause or a call is needed, and the earphone can be controlled to be switched from the working state to the standby state, so that the power consumption of the earphone is reduced. After the user wears the earphone again, the earphone is switched from the standby state to the working state, so that the user can rapidly enter the working state and play the audio signal. In some embodiments, the timing may be started when the earphone is detached and the user holds the earphone, and after a preset time, for example, 30s, it is detected that the user continues to hold the earphone without wearing the earphone, that is, the user only holds the earphone, the music playing is stopped for a long time or the call is made, and the earphone is not worn, and the main controller 30 may control the audio processing circuit 50 to return to the low power consumption state from the standby state, so as to further reduce the power consumption of the earphone and improve the intelligent control capability of the earphone.

The earphone of the invention adopts the first sensor 20 arranged at the rear shell 12 of the earphone and the second sensor 60 arranged at the earplug, so that three different use scenes that a user takes the earphone up and wears the earphone and takes off the earphone can be identified, and corresponding actions can be made according to the different use scenes, thereby realizing the purpose of preventing the earphone from being worn reversely, effectively reducing the power consumption of the earphone, and being more energy-saving and environment-friendly.

Referring to fig. 1 and 2, in one embodiment, the reminder circuit 40 includes a vibration motor (not shown) which is drivingly connected to the main controller 30.

In this embodiment, the motor may be disposed on the casing or disposed in the casing, the vibration motor is controlled by the main controller 30, and when the left earphone is held by the right hand and/or the right earphone is held by the left hand, the main controller 30 determines that the fingers are not matched with the earphones at this time, and outputs the reminding control signal. The vibration motor sends out reminding information to the user according to the reminding control signal so as to remind the user to exchange the held earphones, or remind the user to wear the right earphone by using the left hand and/or wear the left earphone by using the right hand. In this embodiment, the vibration mode and the vibration frequency of the vibration motor are adjustable, that is, the vibration motor may continuously vibrate, or vibrate once, or continuously vibrate two times or three times and then stop vibrating, so as to remind the user. Of course, in other embodiments, the reminding circuit 40 may also be implemented by using other components, such as an LED lamp, and the flashing of the LED lamp may also play a role in reminding the user.

Referring to fig. 1 and 2, it can be understood that, in the above embodiment, in order to further reduce the power consumption of the headset itself, the first sensor 20 and the second sensor 60 are not operated in real time, and after the main controller 30 receives a headset on control command, the first sensor 20 may be operated based on the trigger of the main controller 30, so that the first sensor 20 detects that the headset is not worn reversely. Then the main controller 30 triggers the second sensor 60 to work according to the first detection sensing signal of the first sensor 20, and determines whether the wireless headset is close to the ear of the person according to the detection result of the second sensor 60, and makes the headset enter a working state when determining that the wireless headset is in a wearing state.

It should be noted that the start control instruction may be a trigger button (which may be a physical button or a button, or may be a virtual button on a display screen) provided on the headset, or an off-box (headset box) instruction automatically generated by the headset, or a control instruction sent by the mobile terminal to operate, which is not limited herein.

The invention also provides an earphone control method, which is suitable for the earphone, and the detailed structure of the earphone can refer to the embodiment and is not described again; it can be understood that, because the earphone is used in the earphone control method of the present invention, the embodiment of the earphone control method of the present invention includes all technical solutions of all the embodiments of the earphone, and the achieved technical effects are also completely the same, and are not described herein again.

Referring to fig. 3 and 4, the earphone control method includes the steps of:

s100, detecting the position relation between a human finger and an earphone shell, and generating a first induction detection signal;

step S200, outputting a reminding control signal when the human body finger is determined not to be matched with the earphone according to the first induction detection signal and a preset reference signal;

and step S300, working when the reminding control signal is received so as to send out reminding information.

S400, detecting the position relation between the ears and the earplugs of the human body and generating a second sensing detection signal;

step S500, when the earphone is determined to be in a wearing state according to the second sensing detection signal, the audio processing circuit is triggered to be converted from a standby state to a working state, and a voice reminding signal stored in an earphone memory is acquired and then output;

and S600, when the matching of the human body finger and the earphone is determined according to the first induction detection signal and a preset reference signal, and when the earphone is determined to be in an unworn state according to the second induction detection signal, controlling the earphone audio processing circuit to be converted from a working state to a standby state.

According to the control method of the earphone, after the position relation between the human body finger and the first sensor arranged on the shell is detected and the first sensing detection signal is generated, when the human body finger is determined not to be matched with the earphone according to the first sensing detection signal and the preset reference signal, the reminding control signal is output to remind a user, and the phenomenon that the audiovisual effect of the user is influenced due to the fact that the left earphone and the right earphone are worn wrongly or discomfort is brought to the ears of the user due to the fact that the left earphone and the right earphone are worn wrongly for a long time is prevented.
