Abstract
Description
Technical Field
[0001] This application relates to the field of audio device structure technology, and in particular to an audio output component and an audio device. Background Technology
[0002] Audio devices such as headphones and speakers are widely used in many aspects of life. With the continuous breakthroughs in electronic chip technology, while the functions of audio devices are increasing, users' requirements for the sound quality of audio devices are also getting higher and higher.
[0003] Audio equipment includes electroacoustic transducers such as loudspeakers or horns, which are the core components responsible for converting electrical signals into sound. The cavity housing these electroacoustic transducers is divided into a front cavity and a rear cavity (back sound cavity). These cavities reflect airflow, acting secondary on the diaphragm to increase volume and perform mixing. This places high demands on the cavity; the better the sealing, the better the sound quality.
[0004] Modern audio devices connect to external devices to receive and play audio signals, requiring cables for connection. Alternatively, audio devices may have internal batteries for portability, also necessitating cables for charging. Existing cables consist of wires and plugs, with plugs available in 3.5mm, 6mm, Type-C, and Lightning connectors for easy connection to external devices or power sources. This necessitates the inclusion of corresponding wiring holes or openings on the audio device. However, the design of these holes or openings, or other components connecting to external devices, can lead to air leakage within the cavity of the speaker or other electroacoustic transducer. This prevents effective sealing of the cavity, causing sound leakage along the propagation path and affecting sound clarity and fidelity. Utility Model Content
[0005] Therefore, it is necessary to provide a well-sealed audio output component and audio device to improve sound quality.

[0008] A cover body connects to the housing and seals the receiving cavity; the cover body has an opening communicating with the receiving cavity;
[0009] A speaker is disposed in the receiving cavity and close to the cover, and is positioned opposite to the opening to transmit audio to the outside;
[0010] The mounting structure has a mounting cavity that is independent of the receiving cavity;
[0011] A wiring hole, connecting to the mounting cavity, allows external devices to pass through for connection to the audio output assembly.
[0012] Preferably, the mounting structure is disposed in the receiving cavity, the mounting structure is connected to the housing, and the wiring hole passes through the housing and communicates with the mounting cavity.
[0013] Preferably, the audio output component further includes a connection terminal disposed in the mounting cavity and disposed opposite to the wiring hole, the connection terminal being used to connect the external device.
[0014] Preferably, the housing includes a bottom wall and a side wall connected to the bottom wall, the bottom wall and the side wall enclosing the receiving cavity; the mounting structure includes a side plate and a sealing cover, the side plate is disposed on the side of the bottom wall facing the receiving cavity, and the sealing cover is disposed on the end of the side plate away from the bottom wall, the side plate, the bottom wall, the side wall and the sealing cover enclosing the mounting cavity; the wiring hole penetrates the side wall and communicates with the mounting cavity; the mounting structure further includes a limiting unit disposed in the mounting cavity for limiting the connection terminal.
[0015] Preferably, the limiting unit includes a limiting seat disposed near the wiring hole, the limiting seat being disposed in the mounting cavity and connected to the side wall, and the end of the connecting terminal near the wiring hole being disposed in the limiting seat.
[0016] Preferably, the limiting seat is provided with a limiting groove, which abuts against the connecting terminal; the mounting structure further includes a sealing element; the limiting seat is provided with a snap-fit groove, and the sealing element is disposed in the snap-fit groove and abuts against the connecting terminal and the side wall.
[0017] Preferably, the limiting unit includes a limiting block, which is disposed on the bottom wall and abuts against the end of the connecting terminal away from the wiring hole.
[0018] Preferably, the side plate has a stepped portion at one end away from the bottom wall, and the sealing cover abuts against the stepped portion on one side surface facing the bottom wall; the sealing cover and the side plate are located on the same plane; the mounting structure further includes a connecting column disposed in the mounting cavity, the connecting column is connected to the sealing cover, and the height of the connecting column is the same as the height of the stepped portion.
[0019] Preferably, the number of connecting posts is three, and the three connecting posts are distributed in a triangular pattern; the sealing cover is a printed circuit board.
[0020] Secondly, this application also provides an audio device, including the audio output component as described above.
[0021] The beneficial effects of this application are as follows:
[0022] 1. Compared with the prior art, the audio output component and audio device provided in this application have a sealed receiving cavity in the audio output component and an independent mounting cavity in the receiving cavity, and the wiring hole is connected to the mounting cavity. This ensures the sealing of the receiving cavity when an external device is connected to the audio output component, thereby ensuring that the audio propagates within the receiving cavity without leakage when the receiving cavity is used as a back sound cavity, avoiding the occurrence of sound leakage, and thus ensuring the clarity and fidelity of the sound quality.
[0023] 2. The acoustic chamber is a crucial part of a loudspeaker's operation. When the loudspeaker diaphragm vibrates, it radiates sound waves both forward and backward. The acoustic chamber accommodates these backward sound waves, reducing interference and improving sound quality. In this design, the acoustic chamber is part of a sealed enclosure. By designing mounting structures of identical positions and dimensions, the remaining space within the enclosure is made identical. This design ensures that when the audio output components are used in headphones, the acoustic fields of the two acoustic chambers in the left and right earpieces are consistent, effectively improving sound quality. This ensures that the two audio output components in the audio device output essentially the same audio or have minimal differences in transmission characteristics, guaranteeing that the user's ears receive sound signals in the same or similar frequency bands, resulting in a consistent listening experience and a high-quality audio enjoyment. Of course, the same effect is achieved when the audio output components are used in both left and right audio devices.
[0024] 3. By designing a cavity-type mounting structure, sufficient space is provided to accommodate different types of connection terminals. When the audio output components are used in headphones, the left and right shells can be adapted to different types of cables, such as any two of 3.5mm, 6.5mm, Type-C, and Lightning. Different types of cables correspond to different sizes of connection terminals. Due to the unified design of the mounting structure, it will not affect the mounting cavity, thereby effectively improving the cable diversity of the headphones.
[0025] 4. Through the installation structure design, the back sound cavity is independently separated from the connection terminal installation part, thereby improving the sealing of the back sound cavity and reducing the sound quality damage caused by air leakage.
[0026] 5. The connection terminals are not fixedly assembled within the mounting structure and are assembled by pressing with a sealing cover, which effectively improves assembly efficiency and also optimizes the structure of the audio equipment.
[0027] 6. The sealing cover can be replaced by a PCBA, which can serve as both a cover plate to press the connection terminals and a control panel to provide audio signal conversion functions. This dual-purpose design further optimizes space and makes audio equipment smaller and cheaper. Attached Figure Description

[0045] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.
[0046] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0048] Please see Figures 1 to 3 The images illustrate different forms of audio devices provided in embodiments of this application. For example, ... Figure 1 and Figure 2 As shown, this application embodiment provides an audio device 100, specifically a headset, for wearing on a user's head and outputting audio to the user's ears for audio signal output. It can be understood that the audio device 100 can be a headset, an ear-hook headset, or other types of headphones worn on a part of the user's body.
[0049] like Figure 3 As shown in the embodiment of this application, an audio device 100 is also shown, specifically a speaker, which can be placed on an object to play audio.
[0050] To facilitate understanding of the technical solution of this application, this embodiment uses a headset as an example for description. The headset includes a connecting component 10 and audio output components 20 respectively disposed at both ends of the connecting component 10. The connecting component 10 is used to fix the audio output components 20 on the head and corresponding to the user's ears, so as to provide audio to the user. In this embodiment, the audio output component 20 can be understood as an earphone, whose working principle is based on electromagnetic induction and acoustic principles, converting electrical signals into sound.
[0051] The audio output component 20 houses an audio driver unit, a core component of the headphones. Common types include dynamic, condenser, and electrodynamic drivers. A dynamic driver unit consists of a magnet and a diaphragm; current flowing through the magnet generates a magnetic field, causing the diaphragm to vibrate and produce sound. The audio output component 20 connects to external devices via a connecting cable 200, typically composed of wires and a plug, which affects sound transmission quality. Some high-quality headphones use high-purity copper or silver wire to improve sound quality, while the plug is usually a 3.5mm stereo plug for compatibility with various audio devices. Of course, the plug can also be 6.5mm, Type-C, Lightning, etc.
[0052] To prevent external ambient noise from interfering with the audio output of the audio output component 20, the headphones may also be equipped with sound-isolating materials to reduce external noise interference and provide better sound quality and volume. The design of the housing of the audio output component 20 not only affects its aesthetic appearance but also improves sound quality and user comfort.
[0053] Please see Figure 4 , Figure 4This is a schematic diagram illustrating one usage state of the audio device 100 provided in this embodiment. Only the audio device 100 and the connecting cable 200 are shown in the figure. The plug portion of the connecting cable 200 is connected to the audio output component 20 of the audio device 100. External devices are not shown; however, they can be electronic devices such as computers, tablets, and mobile phones, or other audio devices. The audio device 100 provided in this embodiment is connected to external devices via the connecting cable 200, thereby enabling the input and output of audio signals. In this embodiment, the connecting cable 200 can not only input audio signals from external devices but can also be equipped with a microphone to receive audio signals and transmit them to the audio device 100 or external devices, thus achieving audio input. Of course, the connecting cable 200 can also be connected to an external power source to power the audio device 100 or to charge the battery within the audio device 100.
[0054] The main inventive improvement of the audio device 100 shown in this application embodiment lies in the audio output component 20, which mainly improves sound quality and enhances the user's listening experience through structural design of the housing 21. The audio output component 20 will be described in detail below for better understanding.
[0055] Continue reading Figure 1 and Figure 2 The audio device 100 includes a connection component 10 and an audio output component 20. The audio output component 20 is connected to the connection component 10 and is used to output audio. Specifically, in this embodiment, there are two audio output components 20, which are respectively disposed at both ends of the connection component 10 and are used to output audio signals.
[0056] Please see Figure 5 and Figure 6 The audio output assembly 20 includes a housing 21, a cover 22, a speaker 23, a mounting structure 24, and a wiring hole 25. The housing 21 has a receiving cavity 21a and an opening 21b communicating with the receiving cavity 21a. The cover 22 covers the opening 21b to seal the receiving cavity 21a. The cover 22 has an opening 22a communicating with the receiving cavity 21a. The speaker 23 is located in the receiving cavity 21a and is positioned close to the cover 22, and is positioned opposite to the opening 22a to transmit audio to the outside. The mounting structure 24 is located in the receiving cavity 21a and is connected to the housing 21. The mounting structure 24 has a mounting cavity 241a that is independent of the receiving cavity 21a. The wiring hole 25 passes through the housing 21 and communicates with the mounting cavity 241a, for external devices to pass through to connect to the audio device 100.
[0057] Compared to existing technologies, the audio device 100 provided in this application has a sealed receiving cavity 21a in the audio output component 20, and an independent mounting cavity 241a in the receiving cavity 21a. The wiring hole 25 is connected to the mounting cavity 241a, thereby ensuring the sealing of the receiving cavity 21a when an external device is connected to the audio device 100. This ensures that when the receiving cavity 21a serves as a back sound cavity 21c, audio can be transmitted within it without leakage, avoiding sound leakage and thus ensuring the clarity and fidelity of the sound quality.
[0058] In this application example, the opening 21b of the housing 21 is approximately circular in shape. The housing 21 extends along the axial direction of the opening 21b to form a receiving cavity 21a. Viewed from the axial direction of the opening 21b, the housing portion appears approximately circular. In other embodiments, the shape of the housing 21 can be square, rectangular, or elliptical, etc., and can be adjusted according to aesthetics and requirements. When the audio device 100 is a speaker, the housing 21 can be adaptively designed according to the speaker's shape and spatial layout to meet the assembly and design requirements of the speaker's components.
[0059] Specifically, to improve user comfort, the audio device 100 also includes an earcup assembly 30, which is located on the side of the cover 22 away from the housing 21. The earcup assembly 30 partially protects the ears and head from discomfort during prolonged wear. It includes ear pads, typically made of soft materials such as synthetic leather or sponge. Meanwhile, the connection assembly 10 includes a connector and a cover. The connector is adjustable in length to accommodate different head sizes, further enhancing user comfort. The cover, fitted over the connector, is made of soft materials such as synthetic leather, sponge, or silicone, providing greater comfort when in contact with the user's head.
[0060] Further, please refer to Figure 7 , Figure 8 and Figure 9 The housing 21 includes a bottom wall 211 and a side wall 212 connected to the bottom wall 211. The bottom wall 211 and the side wall 212 enclose the receiving cavity 21a. The mounting structure 24 includes a side plate 241 and a sealing cover 242. The side plate 241 is located on the side of the bottom wall 211 facing the receiving cavity 21a. The sealing cover 242 is located on the end of the side plate 241 away from the bottom wall 211. The side plate 241, the bottom wall 211, the side wall 212, and the sealing cover 242 enclose the mounting cavity 241a. The wiring hole 25 penetrates the side wall 212 and communicates with the mounting cavity 241a.
[0061] Specifically, the side plate 241 divides the receiving cavity 21a into two independent cavities: the mounting cavity 241a and the back sound cavity 21c. This arrangement allows the mounting cavity 241a to connect to the wiring hole 25 for connection to external devices. The back sound cavity 21c is used to allow the rearward-radiating sound waves generated by the vibration of the speaker 23's diaphragm to propagate. Due to the sealed design of the back sound cavity 21c, and the fact that the wiring hole 25 connects to the mounting cavity 241a while the mounting cavity 241a and the back sound cavity 21c are independent and not interconnected, the air inside the back sound cavity 21c is effectively sealed, preventing sound wave leakage and improving sound clarity and fidelity. Simultaneously, the back sound cavity 21c can accommodate these rearward sound waves, reducing mutual interference between sound waves and further improving sound quality.
[0062] To guide the sound in the back sound cavity 21c of the audio output component 20 and improve the sound quality, mounting holes 22b are provided on the cover 22, and auxiliary diaphragms 27 are disposed in the mounting holes 22b. Specifically, the mounting holes 22b are located on opposite sides of the opening 22a, and the auxiliary diaphragms 27 are disposed in each mounting hole 22b. When the speaker 23 outputs sound, the sound emitted from the front of the speaker 23 is output to the outside through the opening 22a; the sound from the back of the speaker 23 propagates in the back sound cavity 21c and, after passing through the auxiliary diaphragm 27, causes the auxiliary diaphragm 27 to vibrate, thereby transmitting the sound in the back sound cavity 21c to the outside and resonating or superimposing with the sound output to the outside through the opening 22a, thus producing the final sound effect and improving the sound quality. In addition, the setting of the auxiliary diaphragm 27 also guides the sound signal to the outside, avoiding the vibration of the housing 21 caused by the repeated propagation of sound in the back sound cavity 21c, and improving the user experience. In this embodiment, the earmuff assembly 30 covers the side of the cover 22 away from the housing 21, and covers the mounting hole 22b and the auxiliary diaphragm 27.
[0063] To ensure that the frequency bands of the sound signals received by the user's two ears are basically the same or have minimal differences, resulting in a consistent listening experience and a high-quality audio enjoyment, in this embodiment, the two audio output components 20 can adopt the same structural design. That is, the receiving cavity 21a and the mounting cavity 241a are designed in the same position and use the same size mounting structure 24. This ensures that the remaining space within the receiving cavity 21a is the same, meaning that the space and layout design of the back sound cavity 21c are the same, thereby achieving a consistent acoustic field between the back sound cavities 21c of the two audio output components 20. It can be understood that using two audio output components 20 with the same structure can also improve production efficiency and assembly efficiency, thereby reducing the production cost of the product.
[0064] In this embodiment, the audio output component 20 further includes a connection terminal 26 disposed in the mounting cavity 241a and opposite to the wiring hole 25. The connection terminal 26 is used to connect the external device and is electrically connected to the speaker 23. The connection terminal 26 is used to connect different types of connection cables 200, specifically, connection cables 200 with different types of plugs, which can be any one of 3.5mm, 6.5mm, Type-C, or Lightning plugs. Therefore, the types of connection terminals 26 are not entirely the same, resulting in different sizes of connection terminals 26; for example, some connection terminals 26 are relatively small, while others are relatively large. In this embodiment, the volume design of the mounting cavity 241a is capable of accommodating various types of connection terminals 26, thereby ensuring that the volume of the mounting cavity 241a is consistent. That is, the side plate 241 is connected to the housing 21 in the housing cavity 21a at the same position, while the volume of the housing cavity 21a in the housing 21 remains unchanged. When the volume of the mounting cavity 241a is determined, the space ratio of the mounting cavity 241a to the housing cavity 21a can be the same, and the structural design of other parts in the housing cavity 21a is the same. This ensures that the space size and structural layout design of the back sound cavity 21c are the same, that is, the shape and structure of the back sound cavity 21c are the same. This ensures that the acoustic field of any two back sound cavities 21c in the produced audio output components 20 is consistent, ensuring that the two audio output components 20 in the audio device 100 output audio that is basically the same or has small differences in sound transmission characteristics, so that the sound signal frequency bands received by the user's two ears are the same or have small differences, resulting in a consistent listening effect. In other embodiments, the audio output component 20 further includes a battery, and the terminal block can be used to connect the battery. The battery is charged by connecting the terminal block via an external connecting wire 200, which is connected to the terminal block 26 via the wiring hole 25. In another embodiment, the terminal block may be omitted, and other connection or charging methods can be used. Simply placing the relevant structure within the mounting cavity 241a and sealing and isolating it from the external sound cavity 21c can achieve the same effect as in the embodiments of this application, improving sound quality.
[0065] Since the types of connecting terminals 26 are different, their sizes also vary. In order to ensure that the connecting terminals 26 are installed firmly in the mounting cavity 241a and to avoid malfunctions or noises caused by shaking, the mounting structure 24 also includes a limiting unit 243 provided in the mounting cavity 241a for limiting the connecting terminals 26.
[0066] In this embodiment, the connecting terminal 26 is of a small size. Taking the connecting terminal 26 for connecting a 3.5mm plug type connecting cable 200 as an example, the description will continue.
[0067] Continue reading Figure 9 The limiting unit 243 includes a limiting seat 2431 disposed near the wiring hole 25. The limiting seat 2431 is located in the mounting cavity 241a and connected to the side wall 212. One end of the connecting terminal 26 near the wiring hole 25 is disposed on the limiting seat 2431. The limiting seat 2431 is provided with a limiting groove 2433, which abuts against the connecting terminal 26. In this embodiment, the limiting groove 2433 is disposed near the wiring hole 25 to tightly abut against the end of the connecting terminal 26 near the wiring hole 25. Specifically, the shape of the limiting groove 2433 matches the shape of the end of the connecting terminal 26 near the wiring hole 25, and is used to abut against the end of the connecting terminal 26 near the wiring hole 25. In this embodiment, the end of the connecting terminal 26 near the wiring hole 25 is cylindrical, and the limiting groove 2433 is semi-circular in shape, so that the cylindrical end of the connecting terminal 26 can be abutted and limited.
[0068] To ensure the sealing of the mounting cavity 241a and improve the installation stability of the connecting terminal 26, the mounting structure 24 further includes a sealing element 245. The limiting seat 2431 has a snap-fit groove 2434, which is located between the limiting groove 2433 and the wiring hole 25. The sealing element 245 is located in the snap-fit groove 2434 and abuts against the connecting terminal 26 and the side wall 212. Specifically, the sealing element 245 is made of silicone or other materials with a certain elasticity or flexibility, and can be completely snapped into the snap-fit groove 2434. One side of the sealing element 245 abuts against the connecting terminal 26, thereby providing a better seal and preventing loosening. Therefore, when the sealing cover 242 is closed on the side plate 241 at the end away from the bottom wall 211, the sealing cover 242 abuts against the sealing element 245, which in turn presses against one end of the connecting terminal 26, thus ensuring the installation stability of the connecting terminal 26. This configuration ensures that the end of the connection terminal 26 closest to the wiring hole 25 can be tightly abutted against the limiting seat 2431 for stable installation.
[0069] To further restrict the connection terminal 26, the limiting unit 243 includes a limiting block 2432, which is disposed on the bottom wall 211 and abuts against the end of the connection terminal 26 away from the wiring hole 25. Specifically, in this embodiment, in the audio output component 20, such as Figure 8As shown, the limiting block 2432 is located in the middle of the mounting cavity 241a and abuts against the two ends of the connecting terminal 26, respectively, with the limiting seat 2431, thereby stably fixing the connecting terminal 26 and ensuring that the connecting terminal 26 is tightly connected to the limiting block 2432 and the limiting seat 2431 to prevent it from shaking.
[0070] Continue reading Figure 7 , Figure 8 The side plate 241 has a stepped portion 2411 at one end away from the bottom wall 211, and the sealing cover 242 abuts against the stepped portion 2411 on one side surface facing the bottom wall 211. Specifically, the thickness of the sealing cover 242 is consistent with the height of the stepped portion 2411, that is, the surface of the sealing cover 242 away from the bottom wall 211 and the surface of the side plate 241 away from the bottom wall 211 are on the same plane. This arrangement ensures that the sealing cover 242 can completely cover the mounting cavity 241a to seal the mounting cavity 241a, and also ensures that the mounting cavity 241a and the receiving cavity 21a are independent of each other and do not affect each other, thereby ensuring that the receiving cavity 21a can be sealed and preventing sound leakage, thus improving sound quality.
[0071] In this embodiment, the sealing cover 242 is a printed circuit board, which saves space and achieves a reasonable use of space layout. At the same time, the printed circuit board is also provided with multiple clearance slots (not shown in the figure) to avoid the pins of the connection terminal 26. The pins of the connection terminal 26 can be electrically connected to the speaker 23 through leads, thereby ensuring that external devices can be electrically connected to the audio output component 20 to input or output audio signals.
[0072] To further ensure the connection stability between the sealing cap 242 and the side plate 241, the mounting structure 24 also includes a connecting post 244 disposed within the mounting cavity 241a. Specifically, the connecting post 244 is disposed adjacent to the side plate 241, and is connected to the sealing cap 242. The height of the connecting post 244 is the same as the height of the step portion 2411. This design ensures that the sealing cap 242 can fit snugly against the step portion 2411, improving connection stability. In this embodiment, the connecting post 244 is provided with a threaded hole 2441, and the sealing cap 242 is provided with a through hole 2421 corresponding to the position of the connecting post 244. The through hole 2421 mates with the threaded hole 2441, and the sealing cap 242 is connected to the connecting post 244 by screws, thereby improving the connection stability of the sealing cap 242.
[0073] Specifically, there are three connecting posts 244, and these three connecting posts 244 are distributed in a triangular pattern. In this embodiment, the mounting cavity 241a formed by the side plate 241 and the housing 21 is approximately cubic in shape, that is, the side plate 241 and the housing 21 form a cuboid shape, wherein the short side of the side plate 241 is opposite to the portion of the housing 21 where the wiring hole 25 is located, and the two long sides of the side plate 241 are opposite to each other and connect the short side portion and the housing 21. The three connecting posts 244 are respectively located on the two long sides and the short side portion, forming a triangular pattern, thereby stably supporting the sealing cover 242. In other embodiments, the cross-section of the mounting cavity 241a formed by the side plate 241 can be square, circular, or elliptical, as long as it can seal the components installed therein and remain independent of the receiving cavity 21a.
[0074] Figures 5 to 9 The structure of an audio output component 20 is shown. Figures 10 to 14 The structure of another audio output component 20 is shown. These two audio output components 20 are respectively located at opposite ends of the connection component 10 to provide audio to the user.
[0075] in, Figures 10 to 14 The structure of the audio output component 20 shown is similar to Figures 5 to 9 The audio output components 20 shown have roughly the same structure, the difference being that the size of the connection terminal 26 provided in the mounting cavity 241a is different. In order to accommodate the larger connection terminal 26, the limiting unit 243 in the mounting cavity 241a is adjusted to limit the connection terminal 26 and ensure the stability of the connection terminal 26.
[0076] The following will discuss Figures 10 to 14 The different structural parts of the audio output component 20 shown are described in detail.
[0077] exist Figures 10 to 14 In the audio output component 20 shown, the connection terminal 26 is of a relatively large size. The following description will continue with the connection terminal 26 for connecting a 6mm plug-type cable 200 as an example.
[0078] In this embodiment, the limiting unit 243 includes a limiting seat 2431 and a limiting block 2432. The limiting seat 2431 is disposed near the wiring hole 25, located in the mounting cavity 241a, and connected to the side wall 212. The end of the connecting terminal 26 near the wiring hole 25 is disposed on the limiting seat 2431. Specifically, the end of the connecting terminal 26 near the wiring hole 25 abuts against the side wall 212. In some embodiments, the end of the connecting terminal 26 near the wiring hole 25 can partially penetrate into the wiring hole 25 and abut against the hole wall of the wiring hole 25 to ensure installation stability. In this embodiment, there is no need to provide a sealing member 245. When the sealing cover 242 is closed on the stepped portion 2411, it can directly abut against the connected terminal 26, thereby stably fixing the connecting terminal 26 in the mounting cavity 241a together with the bottom wall 211, the limiting seat 2431, and the limiting block 2432.
[0079] The limiting block 2432 is located on the side plate 241 away from the wiring hole 25, and abuts against both ends of the connecting terminal 26 with the limiting seat 2431 to limit the connection terminal 26. Specifically, the limiting block 2432 is located on the connecting post 244 opposite to the wiring hole 25.
[0080] In the foregoing embodiments, two different sizes or types of connection terminals 26 are shown. Of course, in other embodiments, the connection terminals 26 can also be connected to connection cables 200 that are compatible with Type-C or Lightning plugs. In this embodiment, the size of the mounting cavity 241a can completely accommodate the connection terminal 26 and is set corresponding to the wiring hole 25, thereby isolating it from the receiving cavity 21a and forming two independent cavities. This ensures the sealing of the back sound cavity 21c, avoids sound leakage, and improves the clarity and fidelity of the sound.
[0081] This application embodiment illustrates two audio output components 20 with largely identical structures, connected to opposite ends of the connecting component 10, to output audio to the user's left and right ears. The difference between the audio output components 20 lies in the subtle differences in the internal structure of the mounting cavity 241a. The size and proportion of the receiving cavity 21a and the mounting cavity 241a remain consistent, ensuring that the shape and structure of the back sound cavity 21c and its proportion within the receiving cavity 21a are also consistent. This results in a consistent acoustic field for the back sound cavity 21c in the audio output components 20 for both ears, effectively improving sound quality while ensuring minimal or no difference in the transmission characteristics of the audio output components 20 for both ears. This ensures that there is a small or no difference in the frequency bands of the sound signals received by the user's two ears, resulting in a consistent listening experience and a stereo effect.
[0082] When the audio output component 20 is applied to a single-use audio device such as a speaker, it can adopt any of the structures described in the foregoing embodiments, and will have the same beneficial effects as described above.
[0083] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The above embodiments only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
