Referring to fig. 1 to fig. 2, fig. 1 is an exploded schematic view of a listening device 10 according to an embodiment of the present disclosure, and fig. 2 is an assembly schematic view of a casing 100, a speaker 200, an isolation frame 300, and a support 400 in fig. 1.

The listening device 10 provided in the embodiment of the present application may be a device with a sound playing function, such as a wireless headset, a wired headset, and a sound box, and the following description only takes the wireless headset as an example of the listening device 10. As shown in fig. 1, the listening device 10 may include: a housing 100, a speaker 200, a bracket 400, and a spacer 300. The speaker 200, the isolation frame 300 and the bracket 400 are disposed in the housing 100. The isolation frame 300 may be located at one side of the speaker 200, and the isolation frame 300 may be used to form a cavity wall of the acoustic cavity of the listening device 10. The stand 400 may connect the housing 100 and the speaker 200, respectively, and the stand 400 may also be used to form the cavity walls of the acoustic cavity of the listening device 10.

Specifically, the housing 100 may be used to mount other functions required for the listening device 10, in addition to the speaker 200, the isolation frame 300, and the stand 400. As shown in fig. 1 to 2, the housing 100 may be provided with a cavity 101 and a sound outlet hole 102 communicating with the cavity 101. The cavity 101 can be used to accommodate the speaker 200, the isolation frame 300, the stand 400, and other functions required by the listening device 10. The sound outlet holes 102 may be used to conduct sound emitted from the speaker 200 to the outside of the cavity 101, so as to implement the sound playing function of the listening device 10. Meanwhile, the material of the casing 100 may be plastic to reduce the weight of the listening device 10, and the shape of the casing 100 may be adapted to the shape of the ear canal of the user to improve the comfort of the user wearing the listening device 10. In addition, the outer surface of the casing 100 may be provided with a functional coating for improving wear resistance and corrosion resistance of the casing 100.

In order to assemble the housing 100 with the functional components such as the speaker 200, the isolation frame 300, and the bracket 400, the housing 100 may be disassembled into the front case 110 and the rear case 120. The front shell 110 and the rear shell 120 may jointly enclose the cavity 101, and the front shell 110 may be provided with the sound outlet 102. Meanwhile, the front case 110 and the rear case 120 may be fixedly coupled by, for example, snapping, bonding, welding, or fusing.

The speaker 200 may be used to convert an electrical signal into an acoustic signal to implement the sound playing function of the listening device 10. As shown in fig. 2, the speaker 200 may be disposed within the cavity 101 and spaced from the walls of the cavity 101. Meanwhile, the sound emitting surface 201 of the speaker 200 may be located on a side of the speaker 200 facing the sound outlet hole 102, and be disposed opposite to the sound outlet hole 102. The speaker 200 may be specifically any one of a moving coil speaker, a moving iron speaker, and a planar diaphragm speaker.

In the embodiment of the present application, all directional indicators (such as up, down, left, right, front, rear \8230;) are used only to explain the relative positional relationship between the components, the motion situation, etc. at a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 3 in conjunction with fig. 2, fig. 3 is a schematic cross-sectional structure of some listening devices 10.

The inventors have found that the front and rear sound cavities of some listening devices 10 are mainly divided by the speaker 200. As shown in fig. 3, the speaker 200 may divide the cavity 101 into a front acoustic chamber 1011 and a rear acoustic chamber 1012. However, the rear acoustic cavity 1012 formed by this solution generally needs to be equipped with functional components of the listening device 10, such as a battery or a circuit board, etc., which may cause the rear acoustic cavity 1012 to be affected by the processing accuracy and the assembling accuracy of the functional components, and further affect the sound quality of the listening device 10. For this reason, the listening apparatus 10 of the present embodiment may be provided with the partition frame 300 for keeping the rear acoustic chamber 1012 independent to improve the acoustic expression of the listening apparatus 10.

As shown in fig. 2, the isolation frame 300 may be located at a side facing away from the sound emitting surface 201 of the speaker 200, that is, a side of the speaker 200 facing away from the sound outlet 102, and the isolation frame 300 may be connected to a cavity wall of the cavity 101, which may be used to separate the cavity 101 into two independent cavities. For example, the side of the isolation frame 300 facing away from the rear sound cavity 1012 and the cavity wall of the housing 100, that is, the cavity 101, may be enclosed to form the accommodating cavity 301, and the accommodating cavity 301 may be used for installing the functional components of the listening device 10, while the side of the isolation frame 300 facing the speaker 200 may be used for forming the cavity wall of the rear sound cavity 1012. With this arrangement, the rear sound cavity 1012 and the accommodating cavity 301 can be separated by the partition frame 300 to maintain the independence of the two, reduce the influence of the functional parts of the listening device 10 on the rear sound cavity 1012, and improve the acoustic performance of the listening device 10.

Spacer 300 may also be used to mount speaker 200 such that speaker 200 may be secured within cavity 101 through spacer 300. For example, the speaker 200 may be disposed on a side of the isolation frame 300 away from the accommodating cavity 301, and the isolation frame and the accommodating cavity may be fixedly connected by bonding, welding, and screws. Meanwhile, the isolation frame 300 may further include an avoidance structure, such as an avoidance groove or an avoidance hole, and the speaker 200 may be disposed in the avoidance groove or the avoidance hole, so as to reduce the stacking height of the speaker 200 and the isolation frame 300. In addition, a sealing member 500, such as sealant, foam, silicone, rubber, etc., may be disposed on the connecting surface between the isolation frame 300 and the cavity wall of the cavity 101 to improve the sealing performance of the rear acoustic cavity 1012.

Optionally, the avoiding hole or the avoiding groove on the isolation frame 300 may also penetrate through the isolation frame 300 to further reduce the stacking height of the speaker 200 and the isolation frame 300, and the speaker 200 may be configured to seal the avoiding hole or the avoiding hole, and form the accommodating cavity 301 together with a side of the isolation frame 300 away from the rear acoustic cavity 1012 and the housing 100, that is, the speaker 200 may also be configured to form a cavity wall of the accommodating cavity 301. Accordingly, the sealing member 500 may be disposed on the connection surface between the isolation frame 300 and the speaker 200 to improve the sealing performance of the rear acoustic chamber 1012.

Further, since the isolation frame 300 partitions part of the rear acoustic cavity 1012 to form the accommodating cavity 301, the design of the isolation frame 300 results in a substantial reduction in the volume of the rear acoustic cavity 1012 (as shown in fig. 2 and 3), while the smaller volume of the rear acoustic cavity 1012 is not favorable for improving the sound quality of the listening device 10. For this reason, the listening device 10 provided in the present embodiment may be provided with the stand 400 for enlarging the rear sound cavity 1012 to improve the sound quality of the listening device 10. As shown in fig. 2, the holder 400 may be disposed in the cavity 101, and the holder 400 may be located on a side of the sound emitting surface 201 near the sound emitting hole 102. Meanwhile, the support 400 may be connected to the housing 100, that is, the cavity wall of the cavity 101 and the speaker 200, respectively, and the support 400 may further enclose a through hole 401 that communicates the sound emitting surface 201 and the sound emitting hole 102. Wherein the inner side wall 402 of the holder 400 facing the through hole 401 may be used to form the cavity wall of the front sound cavity 1011 of the listening device 10, and the outer side wall 403 of the holder 400 facing away from the through hole 401 may be used to form the cavity wall of the rear sound cavity 1012 of the listening device 10.

As shown in fig. 2 and 3, the support 400 provided in this embodiment can divide part of the volume of the front sound cavity 1011 into the rear sound cavity 1012, so that the rear sound cavity 1012 can be expanded from the side of the sound emitting surface 201 away from the sound outlet 102 to the side of the sound emitting surface 201 facing the sound outlet 102, to increase the volume of the rear sound cavity 1012 and reduce the volume of the front sound cavity 1011. In this way, not only can the large rear sound cavity 1012 be used to improve the low frequency flexibility and the dive characteristics of the sound emitted by the loudspeaker 200, but the small front sound cavity 1011 can also be used to broaden the medium to high frequency extension of the sound emitted by the loudspeaker 200, thereby improving the sound quality of the listening device 10.

In particular, the inner side walls 402 may enclose together with the loudspeaker 200 a front sound cavity 1011 of the listening device 10. For example, the opening aperture of the through hole 401 far from the sound emission surface 201 may be equal to the opening aperture of the sound outlet hole 102 near the sound emission surface 201, and the through hole 401 and the sound outlet hole 102 may be exactly aligned. Thus, the cavity wall of the cavity 101 (the housing 100) may not constitute the cavity wall of the front acoustic cavity 1011, and this design may further reduce the volume of the front acoustic cavity 1011.

Alternatively, the inner sidewall 402 may also surround the front sound cavity 1011 of the listening device 10 together with the casing 100 and the speaker 200. For example, the opening aperture of the through hole 401 far from the sound emitting surface 201 may be larger than the opening aperture of the sound emitting hole 102 near the sound emitting surface 201, and the through hole 401 and the sound emitting hole 102 may also be aligned. In this way, the cavity wall of the cavity 101 may also form the cavity wall of the front sound cavity 1011, and the through hole 401 with a larger opening aperture is more favorable for alignment assembly with the sound outlet hole 102.

The outer side wall 403 may enclose a rear acoustic chamber 1012 with the enclosure 100, the speaker 200 and the spacer 300. For example, the speaker 200 and the outer sidewall 403 may each be spaced apart from the cavity wall of the cavity 101 such that the cavity wall of the cavity 101, the speaker 200, the outer sidewall 403, and the spacer 300 may collectively enclose a rear acoustic cavity 1012. Wherein, a partial region of the outer sidewall 403 may be recessed in a direction toward the inner sidewall 402 to form an avoidance space to further enlarge the volume of the rear acoustic cavity 1012. Meanwhile, in order to keep the air pressure balance between the inside of the rear acoustic cavity 1012 and the outside of the listening device 10, the area of the casing 100 forming the cavity wall of the rear acoustic cavity 1012 may be further opened with a pressure relief hole 103. Further, the pressure relief holes 103 may also be covered by a waterproof breathable glue or a waterproof breathable film to reduce the probability of the rear acoustic cavity 1012 entering water stain or dust. Compared with the scheme that the rear sound cavity 1012 is formed by only using the loudspeaker 200, the isolation frame 300 and the cavity wall of the cavity 101 to enclose together, the support 400 can expand the rear sound cavity 1012 to the side of the sound emitting surface 201 facing the sound emitting hole 102, so that the volume of the rear sound cavity 1012 is increased.

As shown in fig. 2, the bracket 400 may also have a bottom wall 404 and a top wall 405 connected to and disposed opposite the inner and outer side walls 402 and 403, respectively. Wherein the bottom wall 404 may be connected to a side of the speaker 200 facing the sound outlet 102 and arranged around the sound emitting surface 201. The top wall 405 may be connected to the cavity wall of the cavity 101 and arranged around the sound outlet opening 102 towards the opening of the loudspeaker 200. In this way, the bracket 400 may be connected to the housing 100 and the speaker 200, respectively, and enclose the through hole 401 that forms the communication between the sound emitting surface 201 and the sound emitting hole 102. Preferably, the bottom wall 404 and the top wall 405 may be parallel.

Further, in order to improve the sealing of the rear acoustic chamber 1012, a sealing member 500 may be disposed between the top wall 405 and the chamber wall of the cavity 101, so as to fill the assembly gap between the top wall 405 and the chamber wall of the cavity 101 with the sealing member 500. When the sealing member 500 is a sealant, it may also serve to bond the casing 100 and the bracket 400, so as to improve the assembly firmness of the bracket 400 and the casing 100. When the sealing member 500 is made of foam, silicone or rubber, the sealing member 500 may be abutted against the top wall 405 of the bracket 400 and the cavity wall of the cavity 101, respectively, to improve the sealing reliability of the bracket 400 and the housing 100. Meanwhile, in order to avoid the deviation of the sealing element 500 in the abutting process, a limit groove for accommodating the sealing element 500 may be further formed in the top wall 405 or the cavity wall of the cavity 101, and the sealing element 500 may be embedded in the top wall 405 or the cavity wall of the cavity 101 through the limit groove, so that the position of the sealing element 500 in the abutting process is limited by the limit groove, and the deviation of the sealing element 500 is avoided.

In order to further improve the sound quality of the listening device 10, the listening device 10 may further include a tuning member 600 for adjusting the sound resistance, and the bracket 400 may further include an acoustic short-circuit hole 406 communicating the front acoustic cavity 1011 and the rear acoustic cavity 1012. As shown in fig. 2, the acoustic short circuit hole 406 extends through the inner sidewall 402 and the outer sidewall 403 to communicate the front acoustic chamber 1011 and the rear acoustic chamber 1012. The tuning member 600 may be affixed to the outer sidewall 403 and cover the acoustic short-circuit hole 406. The tuning member 600 may be tuning cotton or mesh cloth, which may have air permeability, so that the listening device 10 may control the air permeability of the front and rear sound cavities 1011 and 1012 through the tuning member 600, so as to achieve the purpose of tuning. Optionally, the tuning element 600 may also be attached to the inner side wall 402, or directly disposed in the acoustic short-circuit hole 406, and only the tuning element 600 needs to be able to control the air permeability of the acoustic short-circuit hole 406, which is not limited in this embodiment.

Referring to fig. 4 to 6, fig. 4 is another assembly structure diagram of the housing 100, the speaker 200, the isolation frame 300 and the bracket 400 in fig. 1, fig. 5 is another assembly structure diagram of the housing 100, the speaker 200, the isolation frame 300 and the bracket 400 in fig. 1, and fig. 6 is another assembly structure diagram of the housing 100, the speaker 200, the isolation frame 300 and the bracket 400 in fig. 1.

Alternatively, the outer sidewall 403 may only enclose the rear acoustic cavity 1012 with the speaker 200 and the spacer 300. As shown in fig. 4, the listening device 10 may be provided with a connection frame 700 located in the cavity 101 and connected to the isolation frame 300 and the outer sidewall 403 of the stand 400, respectively. Wherein the connection frame 700 can be attached to the cavity wall of the cavity 101 and arranged around the outer side wall 403. In this way, the connecting frame 700 may replace the cavity wall of the cavity 101, and together with the outer side wall 403, the speaker 200 and the isolation frame 300, enclose to form the rear acoustic cavity 1012. In this embodiment, the connection frame 700 and the isolation frame 300 may be an integral structure, and the two may be integrally formed by injection molding or the like.

Optionally, in order to facilitate the positioning assembly of the bracket 400 and the housing 100, a positioning portion 104 may be further disposed on the cavity wall of the cavity 101. As shown in fig. 5, the positioning portion 104 may be disposed around the sound outlet hole 102, the bracket 400 may be located at a side of the positioning portion 104 facing away from the sound outlet hole 102, and the bracket 400 may be disposed around the positioning portion 104. Meanwhile, the inner sidewall 402 may further be provided with a groove for accommodating the positioning portion 104, and the groove may penetrate through the top wall 405 of the bracket 400. In this way, when the bracket 400 and the housing 100 are assembled, positioning assembly can be performed by the positioning portion 104, and the assembly convenience of the bracket 400 and the housing 100 is improved.

Alternatively, in addition to the positioning and assembling by the positioning portion 104, an annular groove for accommodating the bracket 400 may be formed on the cavity wall of the cavity 101, so as to achieve the positioning and assembling of the bracket 400 and the housing 100. For example, an annular groove may be provided around the sound outlet hole 102 and communicate with the sound outlet hole 102, and the supporter 400 may be provided in the annular groove. In this way, when the bracket 400 and the housing 100 are assembled, the bracket 400 can be positioned and assembled on the wall of the cavity 101 by using the annular groove, so that the convenience of assembling the bracket 400 and the housing 100 is improved.

Alternatively, instead of being secured within cavity 101 by spacer 300, speaker 200 may be secured within cavity 101 by bracket 400. As shown in fig. 6, the speaker 200 may be connected to the bottom wall 404 of the bracket 400, and the two may be fixedly connected by means such as bonding, welding, and screwing. Meanwhile, the position of the speaker 200 may also be displaced toward the direction close to the sound outlet hole 102 to be spaced apart from the partition frame 300, thereby enlarging the volume of the rear sound cavity 1012, reducing the volume of the front sound cavity 1011, and improving the sound quality of the listening device 10. In addition, since the speaker 200 is fixed in the cavity 101 by the bracket 400, the sealing member 500 may be a sealant to improve the connection between the bracket 400 and the housing 100.

Optionally, the speaker 200 may also be connected to the wall of the cavity 101 to be fixed within the cavity 101. In order to connect the space of the speaker 200 near the sound outlet hole 102 with the space of the speaker 200 far from the sound outlet hole 102 to form the rear sound cavity 1012, at least a partial region of the peripheral side of the speaker 200 may be spaced from the cavity wall of the cavity 101. In addition, since the speaker 200 can be connected to the cavity wall of the cavity 101 for fixing, the sealing member 500 may be any one of a sealant, a silicone rubber, a rubber, and a foam, which is not limited in this embodiment.

Referring to fig. 7, fig. 7 is another schematic structural diagram of the speaker 200 in fig. 1.

Alternatively, in order to improve the space utilization rate in the cavity 101, the bracket 400 may be a part of the speaker 200, and only the speaker 200 is exemplified as a moving coil type. As shown in fig. 7, the speaker 200 may include: mounting shell 210, diaphragm assembly 220, and bracket 400. The mounting case 210 may have a mounting groove (not shown), the diaphragm assembly 220 may be disposed in the mounting groove, and the diaphragm assembly 220 may vibrate to generate sound after being powered on. The bracket 400 may replace the original front cover of the speaker 200 to be connected to the mounting case 210 and cover the mounting groove, and the through hole 401 formed by surrounding the bracket may communicate the diaphragm assembly 220 and the sound outlet 102, so that the sound emitted by the diaphragm assembly 220 can be transmitted to the sound outlet 102 through the through hole 401. Thus, the original front cover design of the speaker 200 can be omitted, which not only reduces the stacking height of the speaker 200 and the bracket 400, improves the space utilization rate in the cavity 101, but also saves the production cost of the listening device 10.

Specifically, the diaphragm assembly 220 may include: a diaphragm 221, a washer 222, a permanent magnet 223, and a voice coil 224. The diaphragm 221 may be connected to the mounting casing 210, and the diaphragm 221 may cover the mounting groove, and surround the mounting casing 210 to form the inner cavity 202 communicating with the rear sound cavity 1012, which may be used for vibration and sound production. For example, the mounting housing 210 may be formed with a through hole to communicate the inner chamber 202 with the rear acoustic chamber 1012. The washer 222 is located in the inner cavity 202 and spaced apart from the diaphragm 221 to reserve a vibration space for the diaphragm 221. The permanent magnet 223 is disposed on a side of the washer 222 away from the diaphragm 221, and the permanent magnet 223 may be disposed at an interval with a sidewall of the mounting case 210 in the inner cavity 202. The voice coil 224 may be disposed between the permanent magnet 223 and the sidewall of the mounting case 210 located in the inner cavity 202, and connected to the diaphragm 221. When the voice coil 224 is energized to generate magnetic force, the voice coil can interact with the magnetic force of the permanent magnet 223 to displace, so as to drive the diaphragm 221 to move. Therefore, the diaphragm 221 can be driven to vibrate and sound by controlling the magnetic force and the power-on time of the voice coil 224. The specific structure and sounding principle of the moving-coil speaker can be referred to in the prior art, and this embodiment is not described herein again.

The listening device 10 provided by the embodiment of the present application, by disposing the support 400 between the casing 100 and the speaker 200, and the through hole 401 for communicating the speaker 200 and the sound outlet 102 of the casing 100 is surrounded by the support 400, and the cavity wall of the rear sound cavity 1012 of the listening device 10 may include the outer side wall 403 of the support 400 departing from the through hole 401 and the isolation frame 300 located at the side departing from the sound emitting surface 201 of the speaker 200, so that the rear sound cavity 1012 may be expanded to the side of the sound emitting surface 201 facing the sound outlet 102 to increase the volume of the rear sound cavity 1012, which is favorable for improving the sound quality of the listening device 10.
