A sound-collecting portion having a suction-cup-like elasticity for collecting sound from the voice card in which an adhesive is detachably adhered to a peripheral portion of the card;
It is characterized by comprising a bendable hollow voice transmission tube having a leading end communicating with the sound collecting portion, and an earphone communicating with the other end of the voice transmission tube.

In a second hands-free hearing device according to the present invention, the sound collecting portion uses elasticity instead of attaching an adhesive to an edge portion thereof and uses a thin film near a communication portion with the voice tube. And the sound collecting section is brought into close contact with the voice card with a negative pressure.

According to the first hands-free hearing device according to the present invention, since the adhesive is attached to the edge of the sound collecting portion, the sound collecting portion can be brought into close contact with the voice card by the adhesive, so that the sound collecting portion can be collected. There is no need to support the club by hand. In this way, the sound from the sound card is transmitted to the earphone through the hollow voice transmission section using air as a medium. Further, according to the second hands-free hearing device of the present invention, the space for transmitting sound waves from the sound collecting unit to the voice transmitting unit is blocked by a thin film, the sound collecting unit is formed in a suction cup shape, and the concave portion of the suction cup is formed. By pressing against the voice card to reduce the volume of the concave portion and then eliminating the pressing force, the sound collecting portion is attracted to the voice card by the negative pressure, so that it is not necessary to support the sound collecting portion by hand. The sound from the sound card is first vibrated by vibrating the thin film.
Is transmitted to the earphone using air as a medium in the same manner as in the above case.

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic front view of a hands-free hearing device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of FIG.
FIG. 2 is a partial cross-sectional view of FIG. In FIG. 1, reference numeral 1 denotes a sound collecting section having a suction cup-like elasticity for collecting the sound of a voice card (not shown), and 2 denotes a hollow pipe for transmitting the sound collected by the sound collecting section 1 and is bent. The free voice transmission unit 3 is an earphone that transmits the voice transmitted via the voice transmission unit 2 directly to the inside of the ear. In FIG. 2, reference numeral 10 denotes a sound card serving as a sound source, and reference numerals 21 and 21 denote an adhesive mainly composed of a water-based acrylic resin which detachably attaches the sound collecting unit 1 to the sound card 10. In FIG. 3, reference numeral 31 denotes a thin film, which serves to transmit the sound from the sound card 10 in order to maintain the negative pressure when the sound collecting unit 1 is attracted to the sound card with a negative pressure.

Next, a method of using such a hands-free hearing device will be described. First, a case where the sound collecting unit 1 is used in close contact with the voice card 10 using the adhesives 21 and 21 will be described. The sound collecting unit 1 is formed in a suction cup shape, and the adhesives 21 and 21 are attached to an edge of the sound collecting unit 1.
The sound collecting unit 1 is formed by using the adhesives 21
Close contact with 0. Since the adhesives 21 and 21 are attached to the entire edge of the sound collecting unit 1, the outer periphery of the sound collecting unit 1 is completely adhered to the voice card 10. Therefore, the sound is collected by the sound collection unit 1
Is transmitted to the earphone 3 via the voice transmitting unit 2 without leaking from the outside. Therefore, by attaching the earphone 3 to the outer ear, the voice from the voice card 10 can be clearly heard without supporting the sound collection unit 1 with a hand.

Second, a case where the sound collecting unit 1 is fixed to the voice card 10 by using a negative pressure and used will be described. Also in this case, the sound collecting unit 1 is formed in the shape of a suction cup, and is different from the above-described invention in that a cavity is connected from the sound collecting unit 1 to the earphone unit via the voice transmitting unit 2 for transmitting sound. Instead, a thin film is provided near the contact point between the sound collecting unit 1 and the voice transmitting unit 2.
According to the second hands-free hearing instrument of the present invention, the space for transmitting sound waves from the sound collecting section to the voice transmitting section is cut off by a thin film, the sound collecting section is formed in a suction cup shape, and the concave portion of the suction cup is formed by a voice card. To reduce the volume of the concave portion, and thereafter eliminate the pressing force, so that the sound collecting portion is attracted to the voice card by the negative pressure, so that it is not necessary to support the sound collecting portion by hand.

That is, since the sound collecting unit 1 is in close contact with the voice card 10, sound does not leak from the sound collecting unit 1 to the outside, and the thin film 31 vibrates. Due to this vibration, sound is transmitted to the earphone 3 via the voice transmission unit 2 formed of a hollow pipe using air as a medium. Therefore, as in the first case, by attaching the earphone 3 to the outer ear, the voice card 10
It is possible to clearly hear the sound from the user without supporting the sound collecting unit 1 by hand.

The present invention is not limited to the embodiment described above, but can be applied to other methods in other embodiments as long as the gist is not changed. For example, in the present embodiment, one voice tube and one earphone are used, but two voice tubes and two earphones can be used so that the same voice can be heard by two people at the same time.
