Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earphone and a head capable of simultaneously generating two sounds corresponding to respective electric signals based on mutually different electric signals generated by two or more separate sound reproducing players. The present invention relates to a portable voice generating device such as a horn and a voice reproducing system using the portable voice generating device.

[0002]

2. Description of the Related Art Conventionally, various portable voice generators such as earphones and headphones have been proposed. This type of portable voice generation device generally includes a coil to which an electric signal is supplied as a voice generation mechanism and a diaphragm that vibrates based on the electric signal supplied to the coil to generate a voice corresponding to the electric signal. Equipped with a cassette player, compact disc player, IC memory disc player, etc.
It is used by being connected to one audio reproduction player, and the diaphragm is vibrated based on an electric signal reproduced by the audio reproduction player and supplied to the coil to generate a sound.

As described above, the conventional portable voice generating device such as an earphone generates a voice based on an electric signal from one voice reproducing player, and two or more voice generating devices are provided via one voice generating device. It is not intended at all to convert the electrical signal from the audio reproduction player into audio.

[0004]

By the way, in recent years, a cassette player which reproduces voice by running a magnetic tape which is built in a cassette tape and magnetically stores the voice signal, and a compact disc which reproduces the voice signal stored in the compact disc. A player, similarly, an audio reproduction player such as an IC memory disk player which reproduces an audio signal stored in an IC memory disk is used in various learning places.
Especially, it is widely used in language learning and various examinations. Such a sound reproduction player can perform efficient learning because it can be repeatedly listened to as many times as necessary. Especially when learning a language,
If the language to be acquired (eg English) and the mother tongue (eg Japanese for Japanese) can be played back and listened simultaneously via the above-mentioned audio reproduction player, the language acquisition will be further promoted. Therefore, the advent of such a sound reproducing player and a sound generating device thereof is desired.

However, although the above-described conventional audio reproducing player, for example, a cassette player also has a player having two audio reproducing units, each audio reproducing unit reproduces audio from the tape cassette independently of each other.

Therefore, there is a problem that it is impossible to reproduce both English and Japanese at the same time.

Further, in the portable voice generating device such as an earphone used in the conventional voice reproducing player, the voice reproducing player itself is intended to reproduce the voice through one voice reproducing section as described above. Therefore, only one sound is generated based on the electric signal generated by the sound reproducing unit. Therefore, the conventional portable voice generator used in the voice reproduction player has a problem that two voices (for example, English and Japanese) cannot be simultaneously generated due to the voice generation mechanism.

The present invention has been made to solve the above-mentioned conventional problems, and responds to each electric signal based on mutually different electric signals generated by two or more separate sound reproducing players. It is an object of the present invention to provide a portable voice generating device that can generate two voices at the same time and that enables efficient language learning and the like, and a voice reproducing system using the portable voice generating device.

Similarly, the electric signal from the audio reproduction player 2 is
The sound is output to the coil 56 of the sound generating mechanism 50, whereby the coil 56 generates a magnetic force in response to the electric signal. Then, the diaphragm 54 is vibrated corresponding to the magnetic force thus generated. As a result, an English voice and a Japanese voice are simultaneously generated through the vibration of the diaphragm 54. Also in this case, similarly to the above, the English voice and the Japanese voice generated from the voice generating mechanism 50 can be simultaneously heard through the earphone 5B.
