Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone technology, specifically to a headphone with a tuning module. Background Technology
[0002] In existing technologies, in-ear headphones, especially passive in-ear headphones, typically achieve different sound effects through built-in RLC circuits or by using sound outlets with different acoustic parameters. The former can achieve rich adjustment from low to high frequencies, but the adjustment quality of the RLC circuit is not as good as the pure acoustic tuning quality; the latter achieves mid-high frequency adjustment through sound outlets with different acoustic structures, but it is difficult to adjust the low-frequency effect. Utility Model Content

By providing a detachable tuning module on the housing, and by allowing the tuning module to be located in the front cavity, the rear cavity, or both, rich adjustments to the in-ear headphones from low to high frequencies can be achieved through purely acoustic adjustments.
[0006] Preferably, the tuning module is a closed module without any openings.
[0007] Preferably, the tuning module is provided with a tuning hole.
[0008] Preferably, the tuning module is provided with an opening, and the opening is provided with an acoustic damping material mesh with different air permeability.
[0009] Preferably, the tuning module is provided with a diaphragm assembly, which achieves different resonant frequencies through different structures and materials.
[0010] Preferably, the tuning module is fixed to the housing by means of snap-fit, threaded connection or magnetic connection.
[0011] Preferably, the sound outlet is detachable, and the sound outlet is provided with an acoustic damping material mesh with different air permeability.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By incorporating a detachable tuning module on the housing, which can be located in the front cavity, rear cavity, or both, a wide range of frequencies from low to high can be adjusted via purely acoustic means. The tuning module comes in various forms, such as a closed-back module without openings, a module with openings and acoustic damping material meshes of varying permeability, and a module with a diaphragm assembly, to meet different sound effect adjustment needs and improve the adjustment effect and quality. The detachable sound outlet and the acoustic damping material meshes of varying permeability on the sound outlet enable high-quality mid-to-high frequency tuning, which, combined with the low-frequency adjustment of the tuning module, achieves full-frequency sound effect adjustment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1 and Figure 6 This utility model provides an earphone with a tuning module, including a shell 3, an ear cap 1, and a speaker 5. The front end of the shell 3 is provided with a sound outlet 2, the ear cap 1 is fitted on the sound outlet 2, the speaker 5 is disposed inside the shell 3, and the shell 3 is provided with a detachable tuning module 4.
[0023] The front part of the speaker 5 and the sound outlet 2 form a front cavity, the back of the speaker 5 and the housing 3 form a rear cavity, and the tuning module 4 is located at the front cavity, the rear cavity, or both the front cavity and the rear cavity.
[0024] The sound outlet 2 is detachable and is equipped with an acoustic damping material mesh 29 with different air permeability.
[0025] The tuning module 4 is fixed to the housing 3 by means of snap-fit, threaded connection or magnetic connection.
[0026] In practical use, users can choose to replace the appropriate sound outlet 2 and acoustic damping material mesh 2 9 according to their personal sound effect needs to achieve the best listening experience. The design of the tuning module 4 allows users to easily adjust the sound effects without replacing the entire headset, greatly enhancing the headset's practicality and flexibility. Furthermore, the tuning module 4 can be located not only in the front cavity, but also in the rear cavity, or both simultaneously. This design provides more diverse tuning possibilities, allowing users to fine-tune the sound effects to meet the needs of different usage scenarios.
[0027] Example 1:
[0028] Please see Figure 2 Tuning module 4 is a closed module without any openings.
[0029] In practical use, the closed design of the tuning module 4 effectively isolates external environmental interference with the sound effects, providing users with a purer listening experience. When the tuning module 4 is located in the front cavity, its closed design further enhances sound reflection within the front cavity, resulting in a fuller bass effect. When the tuning module 4 is located in the rear cavity, it can adjust the sound resonance of the rear cavity, making the treble clearer and brighter. Furthermore, since the tuning module 4 is detachable, users can easily replace it with different designs or materials according to different music genres and personal preferences to achieve more personalized sound effect adjustments.
[0030] Example 2:
[0031] Please see Figure 3 The tuning module 4 is equipped with a tuning hole 6.
[0032] In practical use, the design of tuning hole 6 allows air to circulate, which in turn affects the resonance and reflection of sound to some extent.
[0033] Example 3:
[0034] Please see Figure 4 The tuning module has openings, and the openings are fitted with acoustic damping material meshes with different air permeability.
[0035] In practical use, the acoustic damping material mesh-7 effectively adjusts the sound's transmittance and damping, thereby affecting the frequency response and timbre. By selecting acoustic damping material mesh-7 with different air permeability, users can adjust the sound's detail and layering according to personal preference and music genre. For example, when emphasizing bass, a lower air permeability acoustic damping material mesh-7 can be selected to reduce the transmission of high-frequency sounds, making the bass deeper and more powerful; while when highlighting treble, a higher air permeability acoustic damping material mesh-7 can be selected to increase the transmission of high-frequency sounds, making the treble clearer and brighter.
[0036] Example 4:
[0037] Please see Figure 5 The tuning module 4 is equipped with a diaphragm assembly 8, which achieves different resonant frequencies through different structures and materials.
[0038] In practical use, the diaphragm assembly 8 can generate different vibration modes according to different audio signals, thereby enabling more precise sound adjustment. By adjusting the structure and materials of the diaphragm assembly 8, it is possible to enhance or weaken specific frequencies of sound, thus meeting the user's personalized needs for sound effects. For example, for users who prefer a deep bass effect, a diaphragm assembly 8 with a lower resonant frequency can be designed to enhance the fullness and impact of the bass; while for users who pursue clear vocals and high-frequency details, a diaphragm assembly 8 with a higher resonant frequency can be selected to highlight the clarity of vocals and the delicacy of high frequencies.
[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
