Embodiment

For describing technology contents of the present utility model, structural feature and purpose of being reached and effect in detail, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the earphone 100 of the adjustable audio of the utility model comprises a headset main body 1, a damping thing 4, an end cap 5 and a pressing mechanism.

See also Fig. 1 and Fig. 2, headset main body 1 comprises an earphone case 11, is formed with a sound chamber 111 in the earphone case 11, and earphone case 11 1 ends are provided with a host cavity 112, and host cavity 112 bottoms are provided with a through hole 115 that is connected with sound chamber 111; Offer two stopper slots 114 on the sidewall of the host cavity 112 of earphone case 11, the sidewall outside of host cavity 112 is provided with a cannelure 113.

See also Fig. 1, damping thing 4 is to be made by the material of flexible and compressible change density such as sponge, elastoplast, weaving or the like, and it is installed in the host cavity 112 of earphone case 11.

See also Fig. 1 to Fig. 4, pressing mechanism is installed on the earphone case 11 and can pushes damping thing 4.In the present embodiment, this pressing mechanism comprises an extrusion 2 and a revolving part 3; Extrusion 2 is contained in host cavity 112 interior also pressure holdings on damping thing 4, extrusion 2 outsides are provided with screw thread 21, offer an intercommunicating pore 24 on the extrusion 2, intercommunicating pore 24 is connected with through hole 115 and sound chamber 111, extrusion 2 one ends convex with two blocked blocks, 22, two blocked blocks 22 and hold respectively and be contained in the stopper slot 114; Extrusion 2 other ends are concaved with a groove 23; Revolving part 3 inboards are provided with the screw thread 31 that matches with screw thread 21 on the extrusion 2, and revolving part 3 one ends are provided with an accepting groove 33, and revolving part 3 is provided with some holding parts 32, and holding part 32 is held in the cannelure 113 of earphone case 11.
