Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and in particular to an adjustable component suitable for an earphone front cavity, an earphone front cavity structure and an earphone. Background Art

[0002] The design of the front cavity of the earphone is a key link in the overall acoustic design of the earphone, and has a direct impact on the sound quality of the earphone. The front cavity usually refers to the part of the duct that is in direct contact with the ear canal in the space in front of the dynamic speaker, involving the propagation path of the sound wave from the dynamic speaker to the eardrum. The size and shape of the front cavity will affect the resonant frequency and sound wave interference, thereby affecting the frequency response curve and sound quality performance.

[0003] In traditional headphone design, the structure and internal volume of the front cavity are not adjustable. This design method brings several obvious defects:

[0004] Firstly, since the volume and shape of the front cavity are fixed, when replacing a dynamic speaker with a different specification or model, the compatibility of the new dynamic speaker with the original front cavity cannot be guaranteed; this usually requires redesigning the front cavity to adapt to the acoustic characteristics of the new dynamic speaker, which leads to increased production costs and extended product development cycle.

[0005] Secondly, the fixed front cavity design limits the ability to adjust the overall frequency response of the headphones. In the overall design of the headphones, the front cavity of the headphones is crucial to the adjustment of the frequency response of the dynamic speaker, which directly affects the user's auditory experience. The fixed front cavity design of the headphones will make it difficult to meet the personalized frequency response needs of different users, thereby reducing the market competitiveness of the product.

[0006] Based on this, it is necessary to improve the structure of the headphone front cavity to make the volume of the headphone front cavity adjustable, thereby improving the compatibility of the headphone front cavity. Utility Model Content

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Example 1

[0029] An adjustable component suitable for the front cavity of an earphone, such as Figure 1 As shown, it includes a component body 1.

[0030] The component body 1 has an outer surface 2 that is adapted to the inner wall of the front cavity, so that the component body 1 can be assembled in the front cavity; further, by adopting component bodies 1 of different volumes and shapes, the volume of the front cavity can be adjusted to adapt to the resonant frequencies required by different dynamic speakers 7, thereby greatly shortening the product development time, effectively reducing production costs, and making the cycle from design to market more efficient.

[0031] The component body 1 is made of elastic material, and the specific material used is not specifically limited. Materials with different elasticity and sound absorption rates can be selected to make full use of the acoustic properties of different materials and match them according to actual acoustic indicators. The elastic material used in this embodiment can adjust the sound wave reflection characteristics and reduce structural resonance, thereby achieving an ideal acoustic effect. By fine-tuning the adjustable component, the frequency response of the headset can be significantly changed to meet the user's personalized preference for sound quality and improve market competitiveness.

[0032] See also Figure 2As shown, the component body 1 is provided with a sound outlet hole 4 connected with the entrance of the sound channel tube 6 to form a sound outlet channel, and the component body 1 can reflect and adjust the passing sound waves; the component body 1 is provided with a pressure relief position 3 connected with the front cavity pressure relief hole 5, so that the pressure relief position 3 can provide a connecting channel for the pressure relief hole 5 of the front cavity, thereby ensuring the balance of air pressure.

[0033] The design of this embodiment facilitates the adjustment of the volume of the earphone front cavity, and helps to solve the compatibility problem of the earphone front cavity with the new dynamic loudspeaker 7.

[0034] Example 2

[0035] This embodiment is based on the technical solution of Embodiment 1, and further explains the design of the pressure relief position 3 and the sound outlet 4 on the component body 1.

[0036] As a preferred solution, see Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the dynamic speaker 7 of this embodiment is installed at the rear end of the component body 1, and a gap is left between the component body 1. The pressure relief position 3 is opened on the side of the component body 1 to correspond to the pressure relief hole 5 opened on the side of the earphone front cavity structure, forming a pressure relief channel, thereby ensuring the free flow of air inside the front cavity through the pressure relief position 3, achieving the conduction between the side pressure relief hole 5 and the inside of the front cavity, avoiding pressure accumulation, and ensuring the balance of air pressure. The internal air flows freely to avoid pressure accumulation, thereby maintaining good sound quality and bass effect

[0037] In addition, the pressure relief position 3 can also be opened at the front end of the component body 1 and penetrate its rear end to correspond to the pressure relief hole 5 opened on the front end surface of the earphone front cavity structure, thereby realizing the conduction between the front end pressure relief hole 5 and the interior of the front cavity to ensure the balance of air pressure.

[0038] Further, see Figure 5 As shown, the pressure relief position 3 is a pressure relief groove opened on the side end of the component body 1, and the pressure relief groove is in a long strip shape. When the long strip pressure relief groove is aligned with the pressure relief hole 5, the axial direction of the sound outlet hole 4 intersects with the axial direction of the sound channel tube 6. In addition, the sound outlet hole 4 can also be set to be coaxial with the sound channel tube 6, and no specific limitation is made here.

[0039] Based on the arrangement of this embodiment, the air pressure balance of the front cavity with the pressure relief hole 5 opened on the side and the air pressure balance of the front cavity with the pressure relief hole 5 opened at the front end can be achieved, thereby improving the overall acoustic performance of the earphone.

By arranging a damping mesh on the inner side of the pressure relief hole 5, this embodiment can further optimize the acoustic performance of the earphone.
