Embodiment Construction

[0018] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

[0019] Such as Figure 1 to Figure 3 As shown, the mechanical earphone tuning structure 100 of the present invention includes a sound cavity housing 1 , a drive unit 2 , a tuning component 3 , at least one damping component 4 and a sealing sponge 5 .

[0020] The sound cavity shell 1 includes a front shell 11 and a rear shell 12 connected to each other, and the front shell 11 and the rear shell 12 jointly form a sound cavity.

[0021] The driving unit 2 is arranged in the front shell 11 of the sound cavity housing 1, and the driving unit 2 is used to emit sound. The sounding principle of the driving unit 2 is the prior art, so it will not be repeated.

[0022] The tuning piece 3 is operatively arranged at the rear end of the rear shell 12 of the sound cavity housing 1 , and at least one tuning hole 31 is opened on the tuning piece 3 , and...

Abstract

The invention provides a mechanical earphone tuning structure. The mechanical earphone tuning structure comprises a sound cavity shell, a driving unit, a tone tuning piece and at least one damping piece; the driving unit is arranged in the sound cavity shell; the driving unit is used for emitting sound, the tone tuning piece is operably arranged on the sound cavity shell; the tone tuning piece isprovided with at least one tuning hole, each tuning hole is covered with a damping member, and the damping members with different dampers are enabled to cover the tuning holes by operating the tuningmember, thereby enabling the air in the sound cavity housing to generate different resonance effects, and achieving a purpose of adjusting the frequency of sound emitted by the earphone.

Description

technical field [0001] The invention relates to the field of earphones, in particular to a mechanical earphone tuning structure. Background technique [0002] The earphones currently on the market adjust the frequency of the sound emitted by the earphone through the sound quality control circuit.
