[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a headphone cavity structure with discrete multiple units, as Figures 1 - 3 shown, including a housing 1. Multiple chambers are provided inside the housing 1, namely a dynamic coil unit placement groove 15, a balanced armature placement groove 16, and a sound insulation material placement groove 17. A dynamic coil unit 3 is provided inside the dynamic coil unit placement groove 15, and a number of balanced armature units 4 are provided inside the balanced armature placement groove 16. A sound outlet 12 is provided at the bottom of the housing 1. Sound transmission channels 18 are provided at the bottoms of both the dynamic coil unit placement groove 15 and the balanced armature placement groove 16. The bottom end of the sound transmission channel 18 is communicated with the sound outlet 12. The discrete design of the dynamic coil unit placement groove 15 and the balanced armature placement groove 16 effectively avoids signal interference between different types of audio drive units. The dynamic coil unit and the balanced armature unit work independently in their respective chambers, can give full play to their respective advantages, and provide a more pure and clear sound quality. Sound transmission channels 18 are provided at the bottoms of both the dynamic coil unit placement groove 15 and the balanced armature placement groove 16. These channels ensure that the sound emitted from the dynamic coil unit 3 and the balanced armature unit 4 can be smoothly transmitted to the sound outlet 12, thereby providing a high-quality audio experience for users. The sound outlet 12 provided at the bottom of the housing 1 is a key part for sound output. It ensures that the sound can be accurately and efficiently transmitted to users, and also helps to reduce the loss of sound during transmission. The dedicated sound insulation material placement groove 17 facilitates the installation of sound insulation materials. This design not only helps to improve the sound insulation performance of the headphones, but also ensures that the sound insulation materials do not interfere with the normal operation of the audio drive units. By adding appropriate sound insulation materials in the sound insulation material placement groove, external noise interference can be further reduced, and the sound clarity and fidelity of the headphones can be improved.

[0023] In this embodiment, sound insulation materials are placed inside the sound insulation material placement groove 17. A pressure relief port 14 is provided on the outer wall of one side of the outer shell 1 near the sound insulation materials, which is used to achieve a certain pressure relief effect. In headphones or other closed systems, when the internal pressure rises to a certain level, the pressure relief port will release excess gas or substances, thereby maintaining the normal pressure inside the system. This helps prevent equipment damage or safety accidents caused by abnormal pressure.

[0024] Specifically, an exhaust port 13 is provided on the outer wall of one side of the outer shell 1. During the use of the headphones, especially when playing audio, certain heat will be generated. The exhaust port 13 serves as an effective heat dissipation channel, which can help discharge this heat, prevent the temperature inside the headphones from being too high, and thus ensure the stable operation of the headphones and extend their service life. The sound quality of the headphones is largely affected by the internal air flow and pressure distribution. The exhaust port 13 helps optimize the sound quality performance by adjusting the internal air flow, ensuring that users can enjoy a high-quality audio experience.

[0025] Furthermore, an opening 11 is provided at the top of the outer shell 1, and a top cover 2 is buckled at the opening 11, which facilitates the opening of the outer shell 1 for the replacement and installation of internal components.

[0026] Furthermore, the outer shell 1 is an integrally formed structure, and the shape of the outer wall is adapted to the shape of the inner wall of the auricle, ensuring comfortable wearing.

[0027] Furthermore, the number of balanced armature units 4 is four, which are arranged side by side in the balanced armature placement groove 16 respectively, facilitating the stable placement of the balanced armature units 4.

[0028] Furthermore, the sound insulation material is made of a cuboid sponge material, which has a good effect of isolating external noise.

[0029] Furthermore, a damping net is installed inside the pressure relief port 14 to prevent external dust from entering and limit the internal sound insulation materials.

[0030] When the discrete multi-unit headphone cavity structure of the present utility model is in use, first, the dynamic coil unit 3 is placed in the dynamic coil unit placement groove 15, and several balanced armature units 4 are placed in the balanced armature placement groove 16. This discrete design ensures that the dynamic coil unit and the balanced armature units work in their respective independent spaces, effectively avoiding signal interference between different types of audio drive units, thereby giving full play to their respective advantages and providing users with a purer and clearer sound quality.

[0031] When an audio signal is input, the moving coil unit 3 and the balanced armature unit 4 will generate sounds respectively. These sounds are smoothly transmitted through the sound transmission channels 18 at the bottoms of their respective chambers to the sound outlet 12 at the bottom of the housing 1. As a key part for sound output, the sound outlet 12 ensures that the sound can be accurately and efficiently transmitted to the user, while reducing the loss of sound during transmission.

[0032] In addition, sound insulation materials are placed inside the sound insulation material placement groove 17, which helps to reduce the interference of external noise and improve the sound clarity and fidelity of the earphone. When the user wears the earphone and plays audio, the exhaust port 13 on one outer wall of the housing 1 will play a role in heat dissipation and optimizing the sound quality. It can help to discharge the heat generated inside the earphone, prevent the temperature from being too high, and ensure the stable operation of the earphone. At the same time, the exhaust port 13 can also regulate the internal air flow and optimize the sound quality performance.

[0033] During the use of the earphone, if the internal pressure rises, the pressure relief port 14 on one side of the housing 1 will release the excess gas or substances to maintain the normal pressure inside the system. This helps to prevent equipment damage or safety accidents caused by abnormal pressure.

[0034] Generally speaking, through reasonable chamber layout, sound transmission channel design, sound insulation and pressure relief structures, etc., the present utility model achieves multiple effects such as improved sound quality, increased sound transmission efficiency, enhanced sound insulation performance, and stable internal pressure, providing users with a better quality and purer audio experience.
