[0020] The present utility model provides a temple structure 100 .

[0021] See also Figures 1 to 4 In one embodiment of the present invention, the temple structure 100 includes a temple body 3, two mid- and low-frequency sound-emitting bodies 1, and a high-frequency sound-emitting body 2. The temple body 3 is provided with a mounting cavity 31, and a side wall of the mounting cavity 31 is provided with a first sound outlet 32; the two mid- and low-frequency sound-emitting bodies 1 are accommodated in the mounting cavity 31, and the two mid- and low-frequency sound-emitting bodies 1 are connected and enclosed to form a sound cavity 11, and a side wall of the sound cavity 11 is provided with a second sound outlet 12, and the second sound outlet 12 is arranged corresponding to the first sound outlet 32. Each of the mid- and low-frequency sound-emitting bodies 1 has a diaphragm 13, and the two diaphragms 13 are spaced apart and arranged opposite to each other; the high-frequency sound-emitting body 2 is accommodated in the mounting cavity 31, and is staggered with the second sound outlet 12 and the two diaphragms 13.

[0022] In the technical solution of the present invention, the mounting cavity 31 is used to accommodate the high-frequency sound-emitting body 2 and the two mid- and low-frequency sound-emitting bodies 1, and the first sound outlet 32 ​​guides the sounds emitted by the high-frequency sound-emitting body 2 and the two mid- and low-frequency sound-emitting bodies 1 from the inside of the temple body 3 to the outside, so as to realize the audio output of the head-mounted device; wherein, the mid- and low-frequency sound-emitting body 1 is responsible for producing rich low-frequency sound effects, and the two mid- and low-frequency sound-emitting bodies 1 are arranged back to back. When the two mid- and low-frequency sound-emitting bodies 1 are working, that is, the two diaphragms 13 vibrate at the same frequency in the direction of approaching each other or in the direction of moving away from each other at the same time, thereby jointly radiating sound waves to the sound cavity 11, causing the air in the sound cavity 11 to vibrate and generate sound, and the sound waves are transmitted to the outside of the mounting cavity 31 and the temple body 3 through the second sound outlet; the two mid- and low-frequency sound-emitting bodies 1 share one sound cavity 11, which effectively saves space and allows for compact head-mounted devices. A more complex audio system is integrated into the device without significantly increasing the size or weight of the device. The design of the shared sound cavity 11 can also allow the vibrations of the two mid- and low-frequency sound bodies 1 to complement each other, thereby enhancing the low-frequency response, and then increasing the sound pressure level, making the bass deeper and more powerful, while maintaining the clarity of the sound quality. The back-to-back mid- and low-frequency sound bodies 1 can also better control the propagation direction of the sound, reduce the reflection and interference of the sound in the sound cavity 11, thereby improving the sound quality, and then enhancing the low-frequency performance of the temple structure 100; while the high-frequency sound body 2 focuses on clear high-frequency details, and the sound emitted by the high-frequency sound body 2 is transmitted from the mounting cavity 31 to the outside of the temple body 3. The high-frequency sound body 2 and the second sound outlet 12 and the two diaphragms 13 are staggered, which helps to accurately restore the high-frequency sound while avoiding interference with the mid- and low-frequency sound. The above design can achieve more accurate sound production, bring richer and more delicate auditory experience, fully present the full-band sound, and greatly meet the user's demand for high-quality audio experience; in this embodiment, the mid- and low-frequency sound-producing body 1 can be a dynamic speaker or a balanced armature speaker, and the present invention does not limit this; the high-frequency sound-producing body 2 can be a piezoelectric speaker or an electrostatic speaker, and the present invention does not limit this; the two mid- and low-frequency sound-producing bodies 1 are arranged back to back, and can be stacked horizontally or vertically. The present invention does not limit this and can be arranged according to the specific speaker structure.

[0023] In another embodiment, the mid- and low-frequency sound-emitting body 1 is preferably a flat dynamic unit, and the high-frequency sound-emitting body 2 is preferably a balanced iron unit. The flat dynamic unit design can significantly reduce the thickness of the temple body 3, so that these units can be easily integrated into the temple structure 100 or other components with limited space, allowing for a richer audio experience without increasing the external size of the device; the flat dynamic unit can provide deep and powerful mid- and low-frequency sounds, while the balanced iron unit is known for its clear and delicate high-frequency response. This combination can provide a wide frequency range and balanced sound quality, thereby enhancing the user's audio experience. At the same time, the balanced iron unit has high sensitivity and low distortion due to its small size and lightweight diaphragm 13, which helps to achieve high-quality audio output at low power, reduce energy consumption, and reduce the weight of the temple structure 100, thereby improving comfort for long-term wearing.

[0024] To achieve accurate positioning and connection of the two mid- and low-frequency sound bodies 1 during installation, please refer to Figure 4 In one embodiment of the present invention, the opposing side walls of the two mid- and low-frequency sounding bodies 1 are respectively provided with a first limiting step 14 and a second limiting step 15, which are adapted to each other. The first limiting step 14 and the second limiting step 15 abut against each other to limit the position. The design of the first limiting step 14 and the second limiting step 15 allows the two mid- and low-frequency sounding bodies 1 to be precisely positioned and fixed during installation, ensuring the relative positional relationship between the two mid- and low-frequency sounding bodies 1, thereby ensuring the formation of the sound cavity 11 and the effective propagation of sound. Through the design of the limiting steps, the two mid- and low-frequency sounding bodies 1 can remain stable after installation, reducing displacement or deformation caused by vibration or other external forces. The adapted limiting steps simplify the assembly process of the mid- and low-frequency sounding bodies 1, making it easier and faster to install the sounding bodies, thereby improving production efficiency.

[0025] To further improve the acoustic performance of the mid-low frequency sounder 1, please refer to Figure 4 In one embodiment of the present invention, the cross-sectional area of ​​the peripheral wall of the second sound outlet 12 gradually increases from the end close to the sound cavity 11 to the end farthest from the sound cavity 11. The gradual increase in the cross-sectional area of ​​the peripheral wall of the sound outlet 12 helps the sound waves to expand gradually when propagating outward from the sound cavity 11, reducing the sudden change and distortion of the sound, thereby improving the sound quality. When the sound waves pass through the sound outlet 12 with a gradually increasing cross-sectional area, the air flow velocity changes more smoothly, thereby reducing the noise generated by air flow turbulence, helping to improve the diffusion of the sound, making the distribution of the sound in the space more uniform, and enhancing the spatial and three-dimensional sense of the sound. The gradual increase in the cross-sectional area also helps to enhance the directionality of the sound, so that the sound is more concentratedly propagated toward the user's ears, improving the clarity and privacy of the sound. The smooth treatment of the peripheral wall of the sound outlet 12 helps to reduce the diffraction of the sound waves at the edge of the sound outlet 12, maintaining the clarity and details of the sound.

[0026] See also Figure 1 In one embodiment of the present invention, the temple body 3 includes a first shell 33 and a second shell 34. The first shell 33 and the second shell 34 are detachably connected and enclose the mounting cavity 31. A side wall of the second shell 34 defines the first sound outlet 32. The design of the first shell 33 and the second shell 34 allows them to be produced separately during the manufacturing process and then assembled together through a detachable connection. This modular design simplifies the production and assembly process and improves production efficiency. The detachable connection allows the user or manufacturer to easily disassemble and reassemble the temple body 3, facilitating maintenance and repair. If the internal audio components need to be replaced or repaired, the entire temple body 3 does not need to be replaced; only the shells need to be disassembled. The detachable shell design makes it easier to maintain and upgrade internal components, helping to extend the product's lifespan. The detachable connection between the first shell 33 and the second shell 34 can be achieved by providing a snap and a slot on each of the first shell 33 and the second shell 34, or by providing a slot on the first shell 33 and a corresponding latch on the second shell 34. The latch is inserted into the slot to achieve connection between the two shells, but this is not limited to this method in the present invention.

[0027] For increased privacy, see Figure 1 In one embodiment of the present invention, an opening 341 is defined on the other side wall of the second shell 34, and the opening 341 is disposed opposite the first sound outlet 32. The second shell 34 also defines an opening 341 on the other side wall, and the opening 341 is disposed opposite the first sound outlet 32. This design allows sound to propagate through the opposing opening 341 and the first sound outlet 32. When sound propagates through the opposing first sound outlet 32 ​​and the opening 341, the sound waveforms at the opposing opening 341 and the first sound outlet 32 ​​differ in phase. By precisely controlling the distance and position between the opposing opening 341 and the first sound outlet 32, the sounds at the opening 341 and the first sound outlet 32 ​​can cancel each other out at specific frequencies, thereby reducing sound leakage. Through the principle of phase cancellation, the possibility of sound leaking from the temple body 3 to the external environment can be significantly reduced, which helps reduce bystanders' perception of what the user is listening to and improves audio privacy.

[0028] To avoid direct contact between the diaphragm 13 and the bottom wall of the second housing 34 when the mid-low frequency sounding body 1 is working, please refer to Figure 2In one embodiment of the present invention, the temple structure 100 includes a support body 4, one side of the support body 4 is connected to one of the mid-low frequency sound-emitting bodies 1, and the side of the support body 4 facing away from the mid-low frequency sound-emitting body 1 is connected to the bottom wall of the second shell 34, so that a first spacing space 5 is formed between one of the mid-low frequency sound-emitting bodies 1 and the bottom wall of the second shell 34. By setting the support body 4, a first spacing space 5 is formed between one of the mid-low frequency sound-emitting bodies 1 and the bottom wall of the second shell 34. The first spacing space 5 can prevent the diaphragm 13 from directly contacting the bottom wall of the second shell 34 during vibration; the connection between the support body 4 and the mid-low frequency sound-emitting body 1 and the second shell 34 can be carried out in a variety of ways, such as bonding or welding, etc., and there is no restriction on this; the design of the support body 4 can effectively protect the diaphragm 13, and avoid the diaphragm 13 from colliding or contacting with the bottom wall of the second shell 34 during vibration, thereby extending the service life of the diaphragm 13; by reducing the direct contact between the diaphragm 13 and the bottom wall of the second shell 34, the noise caused by vibration can be reduced, and the clarity and purity of the sound quality can be improved.

[0029] Likewise, see Figure 2 In one embodiment of the present invention, a second spacing space 6 is formed between the bottom wall of the first shell 33 and the other mid-low frequency sound-emitting body 1. A second spacing space 6 is designed between the bottom wall of the first shell 33 and the other mid-low frequency sound-emitting body 1. The second spacing space 6 can be formed by precisely controlling the distance between the first shell 33 and the mid-low frequency sound-emitting body 1. The second spacing space 6 helps to reduce the vibration generated by the diaphragm 13 when the mid-low frequency sound-emitting body 1 is working and is directly transmitted to the bottom wall of the first shell 33, thereby reducing structure-borne noise and distortion; by forming a spacing space between the mid-low frequency sound-emitting body 1 and the first shell 33, the sound propagation path can be optimized, and the reflection and interference of the sound inside the temple body 3 can be reduced, thereby improving the sound quality; the second spacing space 6 helps to improve the sound quality, by reducing interference during the sound propagation process, making the sound purer and more natural, and by avoiding direct contact between the diaphragm 13 and the first shell 33, it can reduce damage caused by physical collision and extend the service life of the diaphragm 13.

[0030] See also Figure 4In one embodiment of the present invention, a third limiting step 41 is provided on the side of the support body 4 facing the mid-low frequency sound emitting body 1, and a fourth limiting step 16 is provided on the side of the mid-low frequency sound emitting body 1 facing the support body 4. The third limiting step 41 abuts against the fourth limiting step 16 to limit the position. The third limiting step 41 and the fourth limiting step 16 cooperate with each other to ensure that the mid-low frequency sound emitting body 1 is precisely positioned within the support body 4. Through the abutment of the limiting steps, the mid-low frequency sound emitting body 1 is firmly installed on the support body 4, reducing displacement or deformation caused by vibration or other external forces. The design of the limiting step simplifies the assembly process of the mid-low frequency sound emitting body 1. Because the limiting step provides clear installation guidance, manufacturers can more easily and quickly install the low frequency sound emitting body, thereby improving production efficiency.

[0031] Further, see Figure 1 In one embodiment of the present invention, two positioning blocks 342 are formed at intervals on the bottom wall of the second shell 34, and the two positioning blocks 342 are enclosed to form a positioning groove 343, and the high-frequency sounding body 2 and the two medium- and low-frequency sounding bodies 1 are limited to the positioning groove 343. Two positioning blocks 342 are designed on the bottom wall of the second shell 34. These positioning blocks 342 can be raised structures, used to define the boundaries of the positioning groove 343; the gap formed between the two positioning blocks 342 constitutes the positioning groove 343, which is used to accommodate the high-frequency sound body 2 and the two medium and low-frequency sound bodies 1, ensuring that they maintain the correct position and spacing during the installation process; the high-frequency sound body 2 and the medium and low-frequency sound body 1 are precisely placed in the positioning groove 343, and their positions are limited by the positioning blocks 342 to ensure that the sound body will not shift during assembly and use. This design simplifies the assembly process, and the sound body can be easily placed in the positioning groove 343 and fixed. At the same time, if the sound body needs to be maintained or replaced, the design of the positioning groove 343 also makes this process more convenient; the design of the positioning blocks 342 and the positioning groove 343 provides additional support, enhances the stability of the sound body, and reduces displacement or damage caused by vibration. The design of the positioning groove 343 reduces errors in the assembly process, improves production efficiency and product consistency.

[0032] In another embodiment, the low-frequency sound-emitting bodies share a common flexible circuit board, in which a positioning block 342 is provided with a notch for the flexible circuit board to pass through; the medium and low-frequency sound-emitting bodies 1 share a common flexible circuit board, which is responsible for transmitting electrical signals to each sound-emitting body, driving it to vibrate and generate sound; the use of a common flexible circuit board can simplify wiring, reduce the number of required connecting wires, and thus reduce manufacturing costs and complexity; the provision of the notch can simplify the wiring of the medium and low-frequency sound-emitting bodies 1, improve integration and reliability, and also facilitate maintenance and maintain the aesthetics of the equipment.
