The audio device 100 according to the embodiment of the present application is described in detail below with reference to fig. 1 to 7.

As shown in fig. 1, the audio apparatus 100 includes: a body 110, a sound generator 120 and a first sound receiver 130. The body 110 has a receiving chamber 111, a first sound receiving hole 112 and a pressure release hole 113 communicating with the receiving chamber 111; the sounder 120 is disposed within the receiving cavity 111; the first radio 130 is disposed in the accommodating cavity 111; the first sound receiver 130 corresponds to the position of the first sound receiving hole 112 to receive external noise through the first sound receiving hole 112; the first receiving hole 112 and the pressure release hole 113 are located at opposite sides of the body 110 in the width direction.

In the related art, the earphone includes a sound-emitting structure for emitting sound; however, when the sounding structure sounds, pressure is easily accumulated inside the sounding structure, so that the tone quality is changed, and the sound effect emitted by the sounding structure is poor. Whereas the audio device 100 of the present application comprises: a body 110, the body 110 having a receiving chamber 111, a first sound receiving hole 112 and a pressure release hole 113 communicating with the receiving chamber 111; the pressure in the accommodating chamber 111 can be released through the pressure release hole 113, and the influence of the pressure on the sound quality is reduced, thereby improving the sound effect of the audio device 100. Meanwhile, the audio device 100 of the present application further includes a first sound receiver 130 and a first sound receiving hole 112, where the first sound receiver 130 corresponds to the position of the first sound receiving hole 112, so as to receive external noise through the first sound receiving hole 112, thereby further improving the sound receiving effect of the audio device 100 through the first sound receiver 130. For example, the audio device 100 may further include a processor for removing the received sound from the external noise received by the first radio 130 to enhance the effect of the audio device 100 receiving the sound. In addition, in the present application, the first sound receiving hole 112 and the pressure release hole 113 are located at two opposite sides of the width direction of the body 110, so as to increase the distance between the first sound receiving hole 112 and the pressure release hole 113, thereby preventing the sound at the pressure release hole 113 from entering the first sound receiving hole 112, and improving the effect of the first sound receiver 130 for collecting external noise.

In the embodiment of the present application, the body 110 may have a length direction having a relatively large size, a width direction having a relatively small size, and a thickness direction having a minimum size. As an example, as shown in fig. 1, the length direction of the body 110 is a direction a in fig. 2 and 4, the thickness direction of the body 110 is a direction B in fig. 2 and 3, and the width direction of the body 110 is a direction C in fig. 3 and 4.

The shape of the body 110 is not limited. For example, in some embodiments, as shown in fig. 4, the cross section of the body 110 in the thickness direction may be elliptical, so that the body 110 has a smooth outer surface in the thickness direction, and the body 110 can be prevented from being painful or bruising the skin of the user by the smooth outer surface, thereby improving wearing comfort of the audio device 100.

The body 110 has a receiving chamber 111, and the receiving chamber 111 is used to receive the sound generator 120 and the first sound receiver 130 so that the sound generator 120 and the first sound receiver 130 can be protected and fixed by the body 110.

The body 110 has a first sound receiving hole 112 and a pressure release hole 113 communicating with the receiving chamber 111. The first sound receiving hole 112 and the pressure relief hole 113 are respectively communicated with the accommodating cavity 111 and the external environment; external sound can enter the accommodating cavity 111 from the first sound receiving hole 112, and gas in the accommodating cavity 111 can be discharged out of the body 110 from the pressure release hole 113.

The cross-sectional shape of the first sound receiving hole 112 is not limited. For example, in some embodiments, the cross-sectional shape of the first sound receiving aperture 112 may be circular. For another example, in other embodiments, the cross-sectional shape of the first sound receiving aperture 112 may be elliptical.

The cross-sectional shape of the relief hole 113 is not limited. For example, in some embodiments, the cross-sectional shape of the relief aperture 113 may be circular. For another example, in other embodiments, the cross-sectional shape of the relief aperture 113 may be elliptical.

The first sound receiving hole 112 and the pressure release hole 113 are located at two opposite sides of the body 110 in the width direction, so that the distance between the first sound receiving hole 112 and the pressure release hole 113 is increased, sound at the pressure release hole 113 can be prevented from entering the first sound receiving hole 112, and the effect of the first sound receiver 130 for collecting external noise is improved.

For example, in some embodiments, when the audio device 100 is in a wearing state, the pressure release hole 113 is located on a side close to the mouth of the user in the width direction of the body 110, the first sound receiving hole 112 is located on a side far from the mouth of the user in the width direction of the body 110, and the first sound receiving hole 112 can reduce the sound emitted by the user by arranging the first sound receiving hole 112 on the side far from the mouth of the user, so that the accuracy of receiving the external noise by the first sound receiving hole 112 can be improved.

For example, in other embodiments, as shown in fig. 2, an included angle D between the sound receiving direction L1 of the first sound receiving hole 112 and the pressure releasing direction L2 of the pressure releasing hole 113 is between 145 degrees and 170 degrees, and a larger angle is set between the sound receiving direction of the first sound receiving hole 112 and the pressure releasing direction of the pressure releasing hole 113, so that the distance between the first sound receiving hole 112 and the pressure releasing hole 113 can be further increased, and thus sound at the pressure releasing hole 113 can be prevented from entering the first sound receiving hole 112, and the effect of the first sound receiver 130 for collecting external noise is improved.

The sound receiving direction of the first sound receiving hole 112 refers to a direction in which the first sound receiving hole 112 receives sound, that is, the sound receiving direction of the first sound receiving hole 112 is the setting direction of the first sound receiving hole 112, such as the direction L1 in fig. 2 to 4 is the sound receiving direction of the first sound receiving hole 112.

The pressure release direction of the pressure release hole 113 refers to the direction in which the pressure release hole 113 discharges the gas from the inside of the accommodating chamber 111 to the outside, that is, the pressure release direction of the pressure release hole 113 is the installation direction of the pressure release hole 113, and the direction L2 in fig. 2 to 4 is the pressure release direction of the pressure release hole 113.

For another example, in other embodiments, the pressure release hole 113 is located at an end of the body 110 far from the sounder 120 in the length direction of the body 110, and by disposing the pressure release hole 113 at an end of the body 110 far from the sounder 120, the distance between the sounder 120 and the pressure release hole 113 can be increased, so that the sound at the pressure release hole 113 can be prevented from affecting the sound emitted by the sounder 120. The first sound receiving aperture 112 may be located at a non-end portion of the body 110.

Here, as shown in fig. 2, the pressure release direction of the pressure release hole 113 gradually gets away from the sound generator 120 side from the inside of the body 110 to the outside of the body 110 to get away from the sound generator 120; so that the distance between the sound generator 120 and the pressure release hole 113 can be further increased, preventing the sound at the pressure release hole 113 from affecting the sound emitted from the sound generator 120.

In the embodiment of the present application, the structure of the sound generator 120 is not limited as long as the sound generator 120 can generate sound. For example, the sounder 120 may include a horn.

The manner in which the sound generator 120 is disposed in the accommodation chamber 111 is not limited. For example, in some embodiments, the sounder 120 may be removably disposed within the receiving cavity 111 by a snap-fit structure or screws. For another example, in other embodiments, the sounder 120 may be non-detachably disposed within the receiving cavity 111 by ultrasonic welding or adhesive bonding.

As shown in fig. 2, the body 110 may further have a sound emitting hole 118 communicating with the receiving chamber 111, the sound emitting hole 118 and the pressure release hole 113 being located on the same side of the body 110 in the width direction and the thickness direction of the body 110; the sound emitting hole 118 and the pressure release hole 113 are located at opposite sides of the body 110 in the length direction of the body 110; since the body 110 has the largest dimension in the length direction, the distance between the sound emission hole 118 and the pressure release hole 113 can be maximized by arranging the sound emission hole 118 and the pressure release hole 113 on opposite sides of the body 110 in the length direction with the larger dimension, so that the influence of the pressure release hole 113 on the sound of the sound emission hole 118 can be reduced, and the sound emission effect of the audio device 100 can be improved.

In the embodiment of the present application, the structure of the first radio receiver 130 is not limited as long as the first radio receiver 130 can receive sound. For example, the first radio receiver 130 may include a first microphone.

The manner in which the first radio receiver 130 is disposed in the receiving chamber 111 is not limited. For example, in some embodiments, the first radio 130 may be removably disposed within the receiving cavity 111 by a snap-fit structure or a screw. For another example, in other embodiments, the first radio receiver 130 may be non-detachably disposed within the receiving cavity 111 by ultrasonic welding or adhesive bonding.

As shown in fig. 5, the first sound receiver 130 corresponds to the position of the first sound receiving hole 112, so as to receive external noise through the first sound receiving hole 112.

In some alternative implementations of embodiments of the present application, as shown in fig. 2, the body 110 has an oppositely disposed conforming surface 114 and an exposed surface 115 in the thickness direction.

In the present implementation, the pressure release hole 113 is close to the attaching surface 114, and the first sound receiving hole 112 is close to the exposing surface 115; the pressure release hole 113 is close to the attaching surface 114, and the first sound receiving hole 112 is close to the exposing surface 115, so that the distance between the pressure release hole 113 and the first sound receiving hole 112 in the thickness direction of the body 110 can be further increased, sound at the pressure release hole 113 can be further prevented from entering the first sound receiving hole 112, and the effect of the first sound receiver 130 for collecting external noise is improved.

In this implementation manner, as shown in fig. 3, the sound pickup direction of the first sound pickup hole 112 gradually gets away from the attaching surface 114 from the inside of the body 110 to the outside of the body 110, so that the first sound pickup hole 112 is not blocked in the sound pickup direction; so that it is possible to prevent the obstruction from affecting the first sound receiving hole 112 to receive sound.

For example, when the audio device 100 is in a wearing state, there is no ear of the user in the sound receiving direction, that is, the ear of the user does not block the sound receiving direction of the first sound receiving hole 112, so that the first sound receiver 130 can efficiently receive the sound of the external environment through the first sound receiving hole 112, and a good noise reduction effect of the first sound receiver 130 is achieved.

In this implementation manner, as shown in fig. 3, the pressure release direction of the pressure release hole 113 gradually approaches the attaching surface 114 from the inside of the body 110 to the outside of the body 110, so as to be away from the sound receiving direction, thereby further reducing the influence of the pressure release hole 113 on the sound at the first sound receiving hole 112, and further improving the effect of receiving the noise by the first sound receiving hole 112 through the first sound receiving hole 130, that is, achieving a good noise reduction effect of the first sound receiving device 130.

In this implementation, the body 110 may include: a bonding wall 1011 having a bonding surface 114 and a curved wall 1012 located on the peripheral side of the bonding wall 1011; the pressure release hole 113 is provided on the curved wall 1012 side near the adhering wall 1011 so that a gap is formed between the pressure release hole 113 and the face of the user. A gap is formed between the pressure relief hole 113 and the face of the user, the face of the user cannot block the pressure relief hole 113, so that the pressure relief can be ensured to be effectively released through the pressure relief hole 113, the position of the pressure relief opening is far away from the auditory canal, and the released air flow cannot enter the auditory canal and cannot influence the user to hear the sound of the sounder 120; meanwhile, the pressure relief hole 113 is arranged on the side, close to the attachment wall 1011, of the curved wall 1012, so that the distance between the first sound receiving hole 112 and the pressure relief hole 113 can be further increased, sound at the pressure relief hole 113 can be prevented from entering the first sound receiving hole 112, and the effect of the first sound receiver 130 for collecting external noise is improved.

The shape of the bonding wall 1011 is not limited. For example, in some embodiments, the conforming wall 1011 may be a flat wall. For another example, in other embodiments, the conforming wall 1011 may be a wall having a curvature.

The curved wall 1012 can contact the user's skin through the curved surface, thereby preventing the pointed wall from damaging or slamming the user's skin.

In some alternative implementations of embodiments of the present application, the audio device 100 may further include a separation assembly 140, the separation assembly 140 being disposed within the receiving cavity 111; the separation component 140 is disposed between the peripheral wall of the first sound receiving hole 112 and the first sound receiver 130 of the body 110 to define an isolated sound receiving space, so as to prevent airflow sound vibrated by the sound generator 120 from being collected by the first sound receiver 130, ensure that the first sound receiver 130 receives external noise mainly through the first sound receiving hole 112, and improve accuracy of the first sound receiver 130 receiving external noise; thereby ensuring the noise reduction quality.

In the present embodiment, the structure of the partition assembly 140 is not limited.

For example, in some embodiments, the separation assembly 140 may include an annular wall disposed between the peripheral wall of the body 110 and the first sound pickup aperture 112 and the first sound pickup 130 such that an isolated sound pickup space is defined by the annular wall.

For another example, in other embodiments, as shown in fig. 5, the separation assembly 140 may include: a circuit board 141 and a seal 142. The circuit board 141 may be disposed in the accommodating chamber 111; the circuit board 141 has a first via 1411 communicating with the first sound receiving hole 112; the first radio 130 is attached to one side of the circuit board 141 opposite to the first radio hole 112 and corresponds to the position of the first via 1411; the sealing element 142 is clamped between the part of the circuit board 141 located at the periphery of the first through hole 1411 and the wall body of the body 110 located at the periphery of the first sound receiving hole 112, and the sealing element 142 is clamped between the part of the circuit board 141 located at the periphery of the first through hole 1411 and the wall body of the body 110 located at the periphery of the first sound receiving hole 112, so that sound in the accommodating cavity 111 can be prevented from entering the sound receiving space from a gap between the circuit board 141 and the body 110, and the accuracy of receiving external noise by the first sound receiver 130 is further improved; thereby ensuring the noise reduction quality.

In this example, the shape of the seal 142 is not limited. For example, the seal 142 may be a rectangular parallelepiped structure. For another example, the seal 142 may be a columnar structure.

In this example, the material of the seal 142 is not limited. For example, the material of the seal 142 may be rubber. For another example, the material of the seal 142 may be foam.

In this example, the seal 142 may have a through hole communicating the first through hole 1411 and the first sound receiving hole 112 so that sounds of the external environment are received by the first sound receiver 130 through the first sound receiving hole 112, the through hole and the first through hole 1411.

Of course, the sealing member 142 may not have a through hole communicating the first through hole 1411 and the first sound receiving hole 112, at this time, sound of the external environment may pass through the sealing member 142 and enter the first through hole 1411 through the first sound receiving hole 112, and then be received by the first sound receiver 130, at this time, a portion of the sealing member 142 located between the first through hole 1411 and the first sound receiving hole 112 is not compressed, and sound may pass through the sealing member 142.

In this example, the direction of the first sound emission hole 112 and the direction of the first via 1411 may be the same or different. When the sound receiving direction of the first sound receiving hole 112 is the same as the direction of the first through hole 1411, the sound of the external environment can directly enter the first through hole 1411 along the first sound receiving hole 112 and be received by the first sound receiver 130. When the direction of the first receiving hole 112 is different from the direction of the first via 1411, the first receiving hole 112 needs to be set to have two parts with different hole structures in order to ensure the receiving direction of the first receiving hole 112 and ensure the communication between the first receiving hole 112 and the first via 1411.

As an example, the first sound receiving hole 112 includes a pilot sub-hole 1121 located at the outside of the body 110 and a communication sub-hole 1122 located at the inside of the body 110; the reception direction of the pilot sub-hole 1121 is different from the communication direction of the communication sub-hole 1122; the sound receiving direction of the pilot sub-hole 1121 is the sound receiving direction of the first sound receiving hole 112, and the sound of the external environment can enter the communicating sub-hole 1122 and the first through hole 1411 along the sound receiving direction of the pilot sub-hole 1121 and be finally received by the first sound receiver 130; the communicating sub-hole 1122 is used to communicate the first through-hole 1411 with the pilot sub-hole 1121.

In this example, the orientation of the first via 1411 and the orientation of the communicating sub-hole 1122 are not limited. For example, the orientation of the first via 1411 is the same as the orientation of the communicating sub-hole 1122. As an example, the first through hole 1411 and the communicating sub-hole 1122 are provided in the thickness direction of the body 110, and the first through hole 1411 and the communicating sub-hole 1122 communicate so as to communicate the first through hole 1411 and the pilot sub-hole 1121 through the communicating sub-hole 1122. Of course, the orientation of the first via 1411 and the orientation of the communicating sub-hole 1122 may be different.

In this example, the wall body of the body 110 located at the periphery of the communicating sub-hole 1122 may be protruded toward the circuit board 141 to form a space with the circuit board 141 for sandwiching the sealing member 142, so that the sealing member 142 can be tightly sealed between the body 110 and the circuit board 141, ensuring that the first radio receiver 130 receives external noise mainly through the first radio receiving hole 112, and improving the accuracy of the first radio receiver 130 receiving external noise; thereby ensuring the noise reduction quality of the audio device 100.

In some alternative implementations of the embodiments of the present application, as shown in fig. 6 and 7, the body 110 has a partition wall 117 located in the accommodating chamber 111, and the sound generator 120 is disposed at the partition wall 117 and divides the accommodating chamber 111 into a front chamber 1111 and a rear chamber 1112 with the partition wall 117; the first sound receiving hole 112 and the pressure release hole 113 are respectively communicated with the rear cavity 1112, and the first sound receiver 130 is positioned in the rear cavity 1112; the sound generating structure of the sound generator 120 is disposed in the front cavity 1111, for example, the diaphragm of the sound generator 120 is located in the front cavity 1111, that is, the front cavity 1111 is a sound generating cavity; the front cavity 1111 and the rear cavity 1112 are separated by the partition wall 117, so that the influence of the sound emitted by the sound generator 120 on the first radio 130 can be reduced; meanwhile, the front cavity 1111 and the rear cavity 1112 are separated by the partition wall 117, so that the influence of the sound received by the first radio 130 on the sound emitted by the sound generator 120 can be reduced.

In the present embodiment, the body 110 further has a sound emission hole 118 communicating with the front chamber 1111, and the sound emission hole 118 and the pressure release hole 113 are located on the same side of the body 110 in the width direction and the thickness direction of the body 110; the sound emission hole 118 and the pressure release hole 113 are located at opposite sides of the body 110 in the length direction of the body 110 so as to maximize the distance between the sound emission hole 118 and the pressure release hole 113, and reduce the influence of the sound at the pressure release hole 113 on the sound at the sound emission hole 118.

In this implementation, the audio apparatus 100 may further include: a second radio 150, the second radio 150 being disposed within the rear cavity 1112; the body 110 is provided with a second sound receiving hole 119 corresponding to the position of the second sound receiver 150; so that the second sound receiver 150 receives external sounds through the second sound receiving hole 119.

The structure of the second radio receiver 150 is not limited as long as the second radio receiver 150 can receive sound. For example, the second radio 150 may include a second microphone.

The manner in which the second radio 150 is disposed within the receiving cavity 111 is not limited. For example, in some embodiments, the second radio 150 may be removably disposed within the receiving cavity 111 by a snap-fit structure or a screw. For another example, in other embodiments, the second radio 150 may be non-detachably disposed within the receiving cavity 111 by ultrasonic welding or adhesive bonding.

As an example, as shown in fig. 5, the second radio receiver 150 and the first radio receiver 130 are both fixed to the circuit board 141.

The second sound receiving hole 119 is located near the mouth side of the user in the width direction of the body 110 to receive the sound of the user; the second radio receiver 150 is mainly used for receiving the sound of the user, and by arranging the second radio receiving hole 119 on the side of the width direction of the body 110 close to the mouth of the user, the distance between the second radio receiving hole 119 and the mouth of the user can be reduced, and the effect of the second radio receiver 150 for receiving the sound of the user through the second radio receiving hole 119 can be improved.

The second sound receiving hole 119 is located between the sound emitting hole 118 and the pressure release hole 113 in the longitudinal direction of the body 110. Because the size of the body 110 in the length direction is the largest, at this time, the second sound receiving hole 119 is arranged between the sound generating hole 118 and the pressure releasing hole 113, so that the distance between the second sound receiving hole 119 and the pressure releasing hole 113 and the distance between the second sound receiving hole 119 and the sound generating hole 118 can be increased, the sound at the pressure releasing hole 113 does not influence the sound at the sound generating hole 118 or the sound at the second sound receiving hole 119, the sound emitting effect at the sound generating hole 118 is improved, and the sound receiving effect at the second sound receiving hole 119 is improved.

The second sound receiving hole 119 and the pressure release hole 113 are located at two opposite sides of the body 110 in the width direction, so that the distance between the second sound receiving hole 119 and the pressure release hole 113 is increased, sound at the pressure release hole 113 can be prevented from entering the second sound receiving hole 119, and the effect of the second sound receiver 150 for collecting user noise is improved.

In some alternative implementations of embodiments of the present application, the body 110 has a first housing 101 and a second housing 102 fixedly connected in a thickness direction; a housing chamber 111 is defined between the first housing 101 and the second housing 102; to facilitate installation and maintenance of the internal structural components of the body 110.

In this implementation manner, the first housing 101 and the second housing 102 may be detachably and fixedly connected by a fastening structure or a screw, so that the internal structural member of the body 110 is firstly mounted to one of the first housing 101 and the second housing 102, and after the mounting is completed, the other of the first housing 101 and the second housing 102 is connected to the housing mounted with the internal structural member of the body 110; when there is a problem with the internal structural members of the body 110, the first housing 101 and the second housing 102 may be detached, and at this time, the internal structural members of the body 110 may be exposed, so as to facilitate maintenance and replacement of the internal structural members of the body 110.

For example, the sound generator 120, the first sound receiver 130, the second sound receiver 150, and the circuit board 141 may be disposed in the first housing 101; firstly, after the sounder 120, the first radio 130, the second radio 150 and the circuit board 141 are installed on the first shell 101, the second shell 102 is buckled and connected with the first shell 101; when the sounder 120, the first sound receiver 130, the second sound receiver 150, and the circuit board 141 need to be repaired or replaced, the first housing 101 and the second housing 102 are detached again.

Of course, the first housing 101 and the second housing 102 may be fixedly connected in a non-detachable manner. For example, the first housing 101 and the second housing 102 may be fixedly connected non-detachably by ultrasonic welding or adhesive bonding.

In this implementation, the first housing 101 may have a fitting surface 114 to fit the face of the user, i.e., the first housing 101 is located on the side of the body 110 that fits the face of the user; the pressure release hole 113 may be disposed in the first housing 101, and the first sound receiving hole 112 may be disposed in the second housing 102.
