Detailed ways

In order to describe the technical content, structural features, achieved purpose and effect of the present utility model in detail, the following will be described in detail in combination with specific embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the adjustable earphone 100 of the present invention includes a casing 10 , a speaker unit 20 , a wire stopper 30 and a tuning ring 40 .

Please refer to FIG. 2 and FIG. 3 , a resonant cavity 13 is formed inside the housing 10 , the speaker unit 20 is installed in the resonant cavity 13 , and a cylindrical handle 121 extending downward is fixed at the rear of the housing 10 , the lower surface of the handle 121 upwardly defines a through hole 122 communicating with the resonant cavity 13 . Specifically, the housing 10 includes a front shell 11 and a rear shell 12 that covers the front shell 11. The horn unit 20 is arranged between the front shell 11 and the rear shell 12. The horn unit 20 and the front shell 11 A treble inner cavity 131 is formed between them, and a bass inner cavity 132 is formed between the speaker unit 20 and the rear shell 12 . The front shell 11 is provided with a plurality of sound outlet holes 111, and the rear portion of the rear shell 12 is fixed with a cylindrical handle 121 extending downward, and the lower surface of the handle 121 is opened upward to communicate with the bass cavity 132. The through hole 122, the lower end of the handle 121 outer surface offers an annular slot 123, and the handle 121 offers a rectangular vent hole 124 that extends up and down at the slot 123 and communicates with the through hole 122.

Please continue to refer to Figures 2 and 3, the wire stopper 30 has a cylindrical base 31, a plugging portion 32 with a diameter smaller than the base 31 protrudes from the top surface of the base 31, and a transmission cable is connected to the bottom surface of the base 31 ( not shown). The wire stopper 30 is fixed on the lower end of the handle 121 , specifically, the top surface of the base 31 is attached to the lower surface of the handle 121 , and the blocking portion 32 is clamped in the through hole 122 and seals the lower end of the through hole 122 .

Please refer to Fig. 1 to Fig. 4, described tuning ring 40 is circular tube shape, and the opposite two sides of tuning ring 40 offer a first tuning hole 41 that extends up and down and is rectangular and an upper and lower length is the first The second tuning hole 42 of half of the tuning hole 41 .
