An tunable earphone of the present invention will be explained below by way of an embodiment. It should be noted that the embodiments of the present invention are not intended to limit the creation of the present invention in any particular environment, application or special manner as described below. Therefore, the description of the embodiments is only for the purpose of explaining the present invention, and is not intended to limit the present invention.

Please refer to FIG. 1 , which is an exploded view of an embodiment of the present invention. In this embodiment, the present tunable earphone includes an earplug 11, a front case 12, and a speaker. 13. Fixing screw 14, tuning plate 15, sealing ring 16, rear case 17, tuning bar 18, and transmission line 19.

For detailed component connection relationship, please refer to FIG. 2, which is a structural cross-sectional view of an embodiment of the present invention. The front case 13 and the rear case 17 are tightly joined and form a hollow case having a front end hole 21 and a rear end hole 22, and the middle portion is substantially divided by the speaker 13 into the front speaker 23 and the resonance box 24, The sound emitted by the speaker 13 can be resonated by the air in the space of the front speaker 23 and the resonance box 24. According to the size of the front speaker 23 and the resonance box 24 and the distance between the speaker and the inner wall of the two speakers, the overall frequency of the earphone can be determined. The response feature, in simple terms, is different for high-audio and low-audio headphones, which is why.

In this embodiment, the tuning rod 15 has an external thread 181 and an internal thread 182, and the rear end hole 22 has a rear end hole thread 171, so that the tuning rod 15 is inserted into the hollow casing from the rear end hole 22, and can be rotated as needed. In or out, the internal thread 182 can be matched with the fixing screw 14 to fix the tuning board 15 to the tuning rod 15, so that the unscrewing or screwing of the tuning rod 18 will simultaneously drive the tuning board 15 in FIG. Move left and right. In the preferred embodiment, the tuning piece 15 is made of wood, which makes the sound thicker, plastic or rubber, and the fixing screw 14 is made of the same as the tuning piece. The tuning bar 18 is preferably made of metal, but not This is limited.

In order to ensure that air does not escape from the rear end hole 22, the seal ring 16 is disposed between the tuning bar 18 and the inner wall of the hollow casing and substantially blocks the gap between the tuning bar 18 and the inner wall of the hollow casing. Space, and in a preferred embodiment, the sealing ring is made of silicone or rubber to ensure that air in the hollow housing is prevented from entering and exiting the rear end opening 22.
