The application provides an audio device, including: main part 1, bass sound generating mechanism 2, support 3, high pitch sound generating mechanism 4 and control module.
Referring to fig. 1 and 2, the bass sound generating apparatus 2 is fixedly mounted on the main body 1. The support 3 is arranged on the main body 1, one end of the support 3 is rotatably connected with the main body 1, and the other end of the support 3 is provided with a high-pitch sounding device 4.
Referring to fig. 2, the stand 3 is configured to be rotatable to a storage position overlapping with the main body 1. The main body 1 and the bracket 3 are both strip-shaped, and the storage position means that the extension directions of the bracket 3 and the main body 1 are basically consistent and are together. The containing position also comprises that the space occupied by the main body 1 and the bracket 3 is basically superposed, and the space occupied by the two is small.
The stand 3 is also configured to be rotatable to an open position. The main body 1 and the support 3 can be both in a strip shape, the extending directions of the support 3 and the main body 1 are different at the opening position, and an included angle exists between the support 3 and the main body 1. The included angle may be acute, obtuse, and right. As shown in fig. 2, this state is the expanded position of the stent 3.
The stand 3 is rotatably opened from the storage position to the open position. The rotary opening process of the carriage 3 may be a continuous rotary process. The expanded position refers to a maximum position at which the holder 3 can be rotated to be expanded with respect to the stored position. The storage position and the opening position are fixed position points to which the support can move.
The control module can be a chip, a control circuit, a circuit component and the like. The control module is configured to adjust the sound emitting frequency of the high-pitch sound emitting device 4 to a first frequency range when the stand 3 is located at the housing position; in a state where the stand 3 is located at the open position, the sound emission frequency of the high pitch sound emission device 4 is adjusted to a second frequency range having a width larger than that of the first frequency range.
This application is through setting up high pitch sound generating mechanism 4 and bass sound generating mechanism 2 respectively to set up bass sound generating mechanism 2 on main part 1, set up high pitch sound generating mechanism 4 on support 3. The holder 3 is rotatably connected to the main body 1 so that by rotating the holder 3, a change of the position of the high-pitched sound generating apparatus 4 with respect to the main body 1, that is, a change of the position of the high-pitched sound generating apparatus 4 with respect to the ear hole of the wearer, is achieved.
The intelligent glasses of this application still are provided with control module, and control module is used for controlling the sound frequency of high pitch sound generating mechanism 4 and bass sound generating mechanism 2. The human audible sound frequency range is 20-20000 Hz. The sound emission frequency refers to the frequency of the sound emitted from the treble sound emission device 4 and the bass sound emission device 2. The maximum frequency of the treble sound generating means 4 is higher than the maximum frequency of the bass sound generating means 2.
The width of the second frequency range is greater than the width of the first frequency range, that is, in the state where the holder 3 is located at the open position, the range of the sound emission frequency of the high-pitch sound emission device 4 is larger than the state where the holder 3 is located at the housed position, and the high-pitch sound emission device 4 takes on more sound emission. For example, when the stand 3 is located at the accommodated position, the sound emitting frequency (i.e., the first frequency range) of the high-pitched sound emitting device 4 is 500-. When the stand 3 is in the open position, the sound emitting frequency (i.e. the second frequency range) of the high-pitch sound emitting device 4 is 200-. In this case, the range of the sound frequency generated by the high-pitched sound generating device 4 is wider, and more sound heard by the user is generated by the high-pitched sound generating device 4.
Optionally, the control module is configured to adjust the sound emission frequency of the bass sound emission device 2 to a third frequency range having a width smaller than that of the second frequency range in a state where the brackets 3 are located at the open position.
The width of the third frequency range is smaller than that of the second frequency range, including the situation that the maximum value of the third frequency range is overlapped with the minimum value of the second frequency range, and at the moment, the third frequency range is not overlapped with the second frequency range completely; also included is the case where the maximum value of the range of the third frequency is higher than the minimum value of the range of the second frequency, in which case the range of the third frequency overlaps with the range of the second frequency.
When support 3 is located the state of opening the position, the sound frequency that produces of bass sound generating mechanism 2 is less than the sound frequency that produces of high pitch sound generating mechanism 4, and in the sound that intelligence glasses sent this moment, the sound of higher frequency sends through high pitch sound generating mechanism 4, and high pitch sound generating mechanism 4 is located the position that is close to the earhole of the person of wearing this moment for the sound transmission in-process loss of higher frequency is less, strengthens the transmission effect of the sound of higher frequency, makes the person of wearing can be more clear hear the sound.
The third frequency range and the second frequency range collectively cover the entire listening frequency, so that the two sound generating devices collectively emit sound that substantially covers the entire range of sound. Wherein the second frequency range of the high pitch sound generating device 4 is wider, which is responsible for generating sounds in the wider frequency range, so as to provide good listening effect for the user. The third frequency range of the bass sound generating apparatus 2 is relatively narrow, and when such a support 3 is in the open position, the bass sound generating apparatus 2 can mainly play a role of assisting sound generation, providing a certain bass effect. The overall sound effect of the two combined is optimized.
Optionally, the second frequency range overlaps with the third frequency range.
In the state where the holder 3 is in the open position, there is an overlap between the sound emission frequency of the high-pitch sound emission device 4 (i.e., the second frequency range) and the sound emission frequency of the low-pitch sound emission device 2 (i.e., the third frequency range).
The maximum value of the third frequency range is greater than the minimum value of the second frequency range, for example, the third frequency range is 20-300Hz, the second frequency range is 200-15000Hz, and the third frequency range and the second frequency range overlap in the range of 200-300 Hz. That is, the high tone sound generating device 4 and the low tone sound generating device 2 can generate sound at sound frequencies within the overlapping range, thereby improving the sound generating effect of the audio device. Alternatively, the control module is configured to adjust the sound emission frequency of the bass sound emission device 2 to a fourth frequency range having a width larger than that of the first frequency range in a state where the stand 3 is located at the housed position.
As the bracket 3 rotates, the bracket 3 moves from the open position to the housed position, in the process, the high-pitched sound generating apparatus 4 gradually moves away from the ear hole of the wearer, and at this time, the sound emission frequency of the low-pitched sound generating apparatus 2 changes from the third frequency range to the fourth frequency range, and the width of the range gradually increases, that is, the width of the fourth frequency range is larger than that of the third frequency range.
The sound emission frequency of the high-pitch sound emission device 4 changes from the second frequency range to the first frequency range, and the width of the range gradually decreases, i.e., the width of the second frequency range is larger than the width of the first frequency range.
When the stand 3 is moved to the storage position, the width of the fourth frequency range is greater than the width of the first frequency range, and at this time, more sound of the audio device is emitted through the bass sound emission device 2.
Alternatively, the high pitch sound device 4 may not sound at all when the stand 3 is located at the housed position. In this embodiment, when the stand 3 is in the storage position, only the bass sound device 2 performs sound generation. When the support 3 is in the open position, the bass 2 and treble 4 devices share the sound production.
In this embodiment, the first frequency range is 0,
that is, when the holder 3 is located at the storage position, the range of the sound emission frequency of the high-pitch sound emission device 4 is 0, and at this time, the high-pitch sound emission device 4 does not emit sound.
When the support 3 is located the storage position, the high pitch sound generating device 4 does not generate sound, so that the sound leakage of the audio device is reduced, and the integral privacy of the audio device is improved.
Optionally, the control module is configured to adjust the loudness of the treble sound emitting apparatus 4 to a first loudness when the cradle 3 is in the stowed position; in a state where the holder 3 is located at the open position, the loudness of the treble sound emitting device 4 is adjusted to a second loudness that is lower than the first loudness.
Along with support 3 removes to opening the position from accomodating the position, high pitch sound generating mechanism 4 is close to the position of the required transmission of sound more, and high pitch sound generating mechanism 4's loudness reduces gradually this moment, can reduce the leakage of sound to improve the privacy in the sound propagation process. Referring to fig. 2, as the stand 3 rotates clockwise as indicated by the arrow shown in the drawing, in the process of rotating the stand 3 from the storage position to the open position:
the included angle between the bracket 3 and the main body 1 is gradually increased;
under the action of the control module, the high-pass filter is continuously adjusted, so that the first cut-off frequency of the high-pass filter is gradually reduced, and the sound emitting frequency of the high-pitch sound generating device 4 is gradually increased;
the loudness of the high pitch sound generating device 4 is changed from the first loudness to the second loudness, and the loudness of the high pitch sound generating device 4 is gradually reduced;
under the action of the control module, the low-pass filter continuously adjusts, so that the second cut-off frequency of the low-pass filter gradually increases, and the sound emitting frequency of the bass sound generating device 2 gradually decreases;
the loudness of the bass sound emitting apparatus 2 gradually increases.
Optionally, the control module may include a low pass filter, a high pass filter, and a detection circuit. This scheme can detect the relative position relation of support 3 and main part 1 through the detection circuitry, and then adjusts bass sound generating mechanism, high pitch sound generating mechanism's sound frequency range.
The detection line itself has a circuit characteristic that can vary with the relative position of the holder 3 and the main body 1. Alternatively, the circuit characteristic may be a resistance value, an inductance value, or the like, which facilitates a change reaction by a mechanical structure. In practice, for example, the circuit characteristic may be one value when the support 3 is in the stowed position, and the circuit characteristic may change to another value when the support 3 is moved from the stowed position to the deployed position and then to the deployed position. The control module may detect a position and an attitude of the stand with respect to the main body according to a change in a circuit characteristic of the detection circuit.
The high pass filter is used to adjust the width of the sound frequency range of the treble sound generator 4. A high pass filter is electrically connected to the treble sound generator, the high pass filter allowing sound signals having frequencies above a high pass cutoff frequency to flow into the treble sound generator. The sound production frequency range width of the high-pitch sound production device can be adjusted by adjusting the high-pass cut-off frequency.
The low-pass filter is used for adjusting the sound-emitting frequency range width of the bass sound-emitting device 2. The low pass filter is electrically connected with the bass sound generating device and can allow sound signals with frequencies below a low pass cut-off frequency to flow into the bass sound generating device. The sound-emitting frequency range width of the bass sound-emitting device can be adjusted by adjusting the low-pass cut-off frequency.
The scheme utilizes the low-pass filter and the high-pass filter to conveniently and simply realize the sound frequency control of the high-pitch sound generating device and the low-pitch sound generating device. The realization mode is simple and reliable. Further, the relative position between the main body and the support is detected by adopting a detection line, so that the control module can accurately respond to adjust the low-pass cut-off frequency and the high-pass cut-off frequency.
Optionally, the scheme may adopt the resistance value as a circuit characteristic of the detection line for reflecting the position and the posture of the bracket. The resistance value of the detection circuit can be increased or decreased along with the rotation and the movement of the bracket. The control panel controls the filter according to the resistance value change of the detection circuit. The resistance value is the circuit characteristic which is easy to realize continuous change through the matching of a mechanical structure and a circuit, and is suitable for the requirement of the scheme that the filter needs to be adjusted continuously or in stages. In other embodiments, properties such as inductance values may also be used as circuit characteristics.
In an alternative application, the circuit characteristic of the detection circuit may be continuously reduced during movement of the support from the stowed position to the deployed position. Accordingly, the high-pass cut-off frequency of the high-pass filter is configured to be continuously reduced. In this way, the width of the sound emission frequency range of the high-pitch sound emission device can be gradually increased. When the stand is moved to the opened position, the width of the sound emission frequency range of the high-pitched sound emission device is widest.
Further, the low-pass cutoff frequency of the low-pass filter is also configured to continuously decrease. In this way, the width of the sound emission frequency range of the bass sound emission device can be gradually reduced. The width of the sound frequency range of the bass sound emitting apparatus is narrowest when the stand is moved to the open position.
In an alternative application, the circuit characteristic of the detection circuit may be continuously raised during movement of the support from the deployed position to the stowed position. Accordingly, the high-pass cut-off frequency of the high-pass filter is configured to be continuously raised. In this way, the width of the sound emission frequency range of the high-pitch sound emission device is gradually reduced. When the stand is moved fully to the accommodated position, the range of the sound emission frequency of the high pitched sound generating apparatus is narrowest. It may be in a silent form.
Further, the low-pass cutoff frequency of the low-pass filter is also configured to continuously rise. Thus, the width of the sound emission frequency range of the bass sound emission device gradually increases. The range of the sound emission frequency of the bass sound emission device is widest when the stand is moved fully to the storage position.
In this aspect, the variation trend of the circuit characteristic of the detection circuit can be associated with the variation trend of the low-pass cutoff frequency and the high-pass cutoff frequency, so that the sound emission frequency range of the bass and treble sound emission devices can be adjusted in a continuous or stepwise manner by changing the position of the support.
Optionally, the audio device further comprises a transmission assembly, and the transmission assembly is used for realizing movable connection between the bracket and the main body.

The stand 3 is rotated in a counterclockwise direction opposite to the arrow in the position shown in fig. 2, and when the stand 3 is overlapped with the main body 1, the stand 3 is located at the storage position. The rotating shaft 5 is connected with a transmission assembly, and the transmission assembly is used for realizing the positioning of the support 3 in the rotating process, so that the change of the included angle between the support 3 and the main body 1 is realized.
During the rotation of the support 3 from the storage position to the open position, the detection circuit is responsive to the rotation of the shaft 5 relative to the body 1, and the circuit characteristics change. The change of circuit characteristic is fed back to control module with the detection circuitry in the pivot 5 rotation process, and along with the change of support 3 and main part 1 support contained angle, the change of the sound frequency of the sound production of control unit module realization to high pitch sound production device 4 and bass sound production device 2.

At this time, the range of the sound emission frequency of the bass sound emission device 2 (i.e., the third frequency range) is smaller than the range of the sound emission frequency of the treble sound emission device 4 (i.e., the second frequency range). Meaning that more of the sound in the audio device is emitted through the treble sound generator 4 and delivered to the ear hole location of the wearer.
In the application, the high-pitch sound production device 4 is moved to a position close to the ear hole of the wearer by rotating the bracket from the storage position to the open position; meanwhile, the range of the sound production frequency of the high-pitch sound production device 4 is improved and the range of the sound production frequency of the low-pitch sound production device 2 is reduced by matching with the control module.
High pitch sound generating mechanism 4's sensitivity is high, and its range increase of sound frequency, and the sound that can make bigger frequency range transmits to the person's of wearing ear hole position from high pitch sound generating mechanism 4's position, reduces the loss of the sound that audio frequency device sent in the transmission course, has higher sound accuracy, improves the sound transmission effect of intelligent glasses, and then improves the tone quality and the listening effect of intelligent glasses. In addition, when the stand 2 is located at the housed position, the loudness of the high-pitched sound generating apparatus 4 is high; and when the stand 3 is in the open position, the loudness of the treble sound generating means 4 is low. When support 3 is located the state of opening the position, reduce high pitch sound generating mechanism 4's loudness, when guaranteeing that the person of wearing can clearly hear the sound, reduce the external possibility of hearing the sound of intelligent glasses to improve the privacy of intelligent glasses product.
