Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an earplug earphone with a cover that is used by inserting it into an ear canal.

[0002]

[Prior art]

 In a conventional earplug earphone, generally, as shown in FIG. 5, an earplug portion 2 is projectingly provided on a disk-shaped housing 1 having a built-in acoustic conversion portion. As shown in the same figure, the earplug 2 is of a type in which a substantially bell-shaped one is provided upright in the center of the housing 1, and a doglegged shape is provided at a position deviated from the center of the housing 1. There is a type in which the earplug is bent into a protruding shape, and in either case, the earplug is used by inserting it into the ear canal.

[0003]

[Problems to be solved by the device]

 Conventional earplug earphones have open holes in the earplugs, so they have the disadvantage that earwax accumulates in the earplugs during use and the holes are blocked and you cannot hear the sound. . Further, since the earplug is made of a hard resin, it feels uncomfortable when it is attached to the ear canal, and in particular, the earplug is cold in winter, which causes discomfort when it is attached. Further, since the outer peripheral surface of the earplug portion is formed smooth, it is easy to slip out of the ear canal. In addition, there was a problem that the sound leaked from the ear canal was large and annoyed the surroundings, and the sound from the outside was mixed.

The present invention has been made in view of the above-mentioned circumstances, and an ear with a cover that can be stably and satisfactorily attached to an ear canal and is excellent in sound quality, can reduce sound leakage, and can block mixing of sound from the outside. It is intended to provide a plug-type earphone.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that an earplug portion of an earplug earphone is detachably fitted with an earphone cover made of a sponge material.

[0006]

[Action]

 According to the present invention, since the spongy material cover is fitted on the earplug portion, if the earplug portion is inserted into the ear canal as usual, the earplug portion is softly attached without any discomfort, and the cover is elastic. As it deforms and fits closely to the ear canal, it is stably attached and prevented from coming off the ear canal. In addition, reducing sound leakage from the ear canal prevents external sound from entering and softens the sound.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of an earplug earphone with a cover according to the present invention, FIG. 2 is a vertical sectional view of an earphone cover, and FIG. 3 is a vertical sectional view of the earphone covered with the cover. Is.

1 to 3, the earplug earphone 1 of this embodiment has a disc-shaped housing 2 made of a hard resin containing an acoustic transducer, which is located at a position offset from the center. An earplug portion 3 made of a hard resin bent in a dogleg shape is attached, and this earphone 1 has the same structure as a commercially available one. Reference numeral 3a denotes an acoustic hole of the earplug portion 3 that guides the sound from the acoustic conversion portion to the outside. Reference numeral 4 denotes a cord connected to the acoustic conversion portion and led out from the housing.

Reference numeral 5 denotes an earphone cover that covers the earphone 1. The cover 5 of this embodiment includes an earplug cover portion 6 that is fitted to the earplug portion 3 and a housing that is fitted to the housing 2 of the acoustic conversion portion. And a cover portion 7 for use. The earphone cover 5 is made of a sponge material such as urethane foam, the earplug cover portion 6 is formed in a substantially bell shape having an opening 6a on the lower surface, and the housing cover portion 7 is formed in a substantially rubber tire shape. Circular openings 7a and 7b are provided on the upper and lower surfaces. Then, the opening 6a of the earplug cover 6 and one opening 7a of the housing cover 7 are aligned and bonded with an adhesive. In this case, it is also possible to integrally form both from the beginning.

The earphone cover 5 of the embodiment is composed of the earplug cover part 6 and the housing cover part 7 as described above, but the cover 5 may be composed of only the earplug cover part 6. It is possible, and in this case, it is preferable that the opening 6a is squeezed narrowly so as to be strongly attached to the base of the earplug 3. Further, the openings 7a and 7b of the housing cover portion 7 of the embodiment are formed at the centers of the upper and lower surfaces of the cover portion 7, respectively, but the upper opening 7a is a dogleg-shaped earplug portion. It may be formed so as to be deviated from the center so as to correspond to No. 3, and even with such a configuration, it can be used commonly for the earphone of the embodiment of FIG. 4 described later.

The earphone cover 5 is configured as described above, the opening 7b on the lower surface of the cover portion 7 is enlarged, and the cover 5 is fitted to the earphone 1 from the earplug portion 3 side of the earphone 1 to increase the expansion force. When released, the earplug portion 3 is entirely covered with the earplug cover portion 6, and the housing 2 is covered with the housing cover portion 7 except for the take-out portion of the cord 4 and the central portion of the lower surface. The peripheral edge of the opening 7b of the cover portion 7 is elastically engaged with the peripheral edge of the lower surface of the housing 2, and the cover 5 is detachably fitted to the earphone 1.

FIG. 4 shows another embodiment of the present invention. In this embodiment, the earplug portion 3 of the earplug earphone 1 is formed in a substantially bell shape, and the earplug portion 3 of the housing 2 is formed. The upright arrangement in the center is different from the above-described embodiment, and the other configurations are exactly the same as the above-mentioned embodiment.

[0013]

[Effect of device]

 The present invention has the following effects.

Since the sponge-like cover is fitted on the earplug portion 3 of the earphone 1, the earplug portion 3 can be worn with a soft touch without any discomfort when it is inserted into the ear canal.

It is possible to reliably prevent earwax from entering the hole 3a of the earplug portion 3 and blocking the hole.

The friction resistance of the earphone cover of the earplug unit 3 stabilizes the mounting, and prevents the earplug unit 3 from being accidentally detached from the ear canal.

It is possible to reduce sound leakage from between the ear canal and to block mixing of sound from the outside.
