Problems solved by technology

[0002] The traditional headphone cavity cannot adjust the sensitivity of different frequency bands in a targeted manner, and needs to be precisely matched with the speaker
Its adjustment sensitivity is poor and adjustment is difficult. For headphones with high sound quality requirements, it can only be adjusted through other accessories such as speakers and electronic circuits, and it is difficult to have comprehensive adaptability; moreover, the selection range of spare parts in the design is narrow, and the cost investment is high. , not conducive to the development

Embodiment Construction

[0028] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0029] The earphone acoustic cavity structure disclosed in the present invention is applicable to various types of earphones, such as in-ear, ear-hanging, and head-mounted. This embodiment is a specific implementation of the earphone.

[0030] Such as Figure 1-3 As shown, an earphone acoustic cavity structure includes a fixedly connected back shell and a backing plate. The back shell and the backing plate are snapped together by a buckle structure and locked and fixed by screws. There are horns inside the back shell and the backing plate. The surface of the body is exposed outside the backing plate, the side is surrounded by the middle tuning cavity, and the back side exposes the middle tuning cavity towards the inner cavity of the rear shell. The middle tuning cavity surrounds the sides of the horn and is tightly f...

Abstract

The invention provides an earphone acoustic cavity structure. The structure comprises an earphone acoustic cavity, a loudspeaker is arranged in the earphone acoustic cavity, and the earphone cavity further comprises a middle toning cavity which is arranged in the earphone cavity and surrounds the side periphery of the loudspeaker; the middle toning cavity further comprises a vent hole and the sound frequency band is regulated by regulating the ventilation property of the vent hole. A small-volume cavity is formed around the loudspeaker by setting the middle toning cavity, and the sounds at different frequency bands are effectively enhanced or weakened by adjusting the air damping of the vent hole; the earphone can extremely and conveniently adjust the frequency band of 20-4000Hz; and the important is that the electronic circuit for setting a low-frequency filter and a balancer is reduced for the earphone, and a more simplified adjusting way is brought for the earphone sound design. The problem that multiple frequency bands cannot be adjusted in the way of matching and adjusting the electronic circuit or the loudspeaker is solved. The structure provided by the invention can allow more extensive material and size selection on the parts by a designer.

Description

technical field [0001] The invention relates to the field of earphone structure design, in particular to an earphone acoustic cavity structure. Background technique [0002] The traditional earphone cavity cannot adjust the sensitivity of different frequency bands in a targeted manner, and needs to be precisely matched with the speaker. Its adjustment sensitivity is poor and adjustment is difficult. For headphones with high sound quality requirements, it can only be adjusted through other accessories such as speakers and electronic circuits, and it is difficult to have comprehensive adaptability; moreover, the selection range of spare parts in the design is narrow, and the cost investment is high. , is not conducive to development. Contents of the invention [0003] The present invention aims to solve the above problems, and provides an earphone acoustic cavity structure capable of adjusting sounds in different frequency bands without an electronic circuit. [0004] In o...
