Embodiment
[0023] Fig. 2 is a perspective view showing an example of an embodiment of the earphone of the present invention.
[0024] In FIG. 2, the earphone component 10 has a structure in which a speaker (not shown) is built in the speaker housing 11 of the speaker main body inserted into the ear of the listener, and a lead wire is formed integrally at the rear of the speaker housing 11. The connecting wire 13 connected to the speaker is led out from the wire leading portion 12.
[0025] The outer peripheral portion 11A of the speaker housing 11 of the earphone component 10 is molded into a substantially circular shape with a rubber material harder than sponge, and its outer diameter is set to be, for example, larger than figure 1 The diameter d2, which is a small standard diameter like the earphone of (B).
[0026] The headphone component 10 is equipped with a size conversion ring 14 which is externally fitted on the outer peripheral portion 11A of the speaker housing 11 and is integrate...

The objective of the invention is to provide an earphone unit which a purchaser of the earphone unit can use in a state in matching with the size of its own ear after the purchase of the earphone unit. A diameter of an outer circumferential face of a speaker case 11 of the earphone for incorporating a speaker and to be inserted into an ear shell of a person is set to be a required diameter smaller than a standard size in an ear shell of an ear of an average person and the speaker case 11 is formed, the earphone is provided with a size conversion ring 14 having an inner circumferential face 14B and an outer circumferential face 14A similarly formed to the shape of the outer circumferential face of the speaker case 11 with the diameter above wherein the diameter of the outer circumferential face 14A is set to be a standard size in the ear shell of the ear of the average person, and the size conversion ring 14 is outwardly fitted to the speaker case 11 to be integrated with the speaker case 11.
Description
Technical field [0001] The present invention relates to the structure of earphones. Background technique [0002] Generally, earphones are used when listening to portable audio equipment, etc., by inserting them into the ear of the listener and wearing them (for example, refer to Patent Document 1). [0003] Here, the size of the human ears is different. When the shape of the earphone is inserted into the ear of the listener and the speaker housing with built-in speakers is smaller than the size of the ear of the listener, the earphone is unstable in the ear of the listener. It may cause poor adhesion with the ear, or fall off from the ear during use; in addition, when the shape of the speaker shell of the earphone is larger than the size of the ear of the listener, the outer peripheral part of the speaker shell presses the inner wall of the ear , Bring uncomfortable feeling to the listener, and cause the problem that it is difficult to use for a long time. [0004] In the past, ...
