JPH071686U - Lightweight self pronunciation listening device - Google Patents

Abstract

(57) [Abstract] [Purpose] A lightweight self-pronunciation listening device to make it easier to hear self-pronunciation mainly for language training in a general noise environment such as on a commuter train [Structure] One ear shell of one's own The earphone, amplifier, power supply battery, and power switch are integrated into the part to be attached to, the flexible hard tube extends from the amplifier to the mouth, and a small super-directional microphone is attached to the tip.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is a device that allows a person with ordinary hearing ability to accurately and clearly hear the pronunciation of a small self when learning a language in a general noise environment.

[0002]

[Prior art]

 There is no small listening device dedicated to language learning, and if a conventional one is used instead, a multipurpose sound collector must be used. For example, a hearing aid is a large listening device that can be held by hand. However, in that case, it is designed to collect all the surrounding sounds for that purpose, and it is not suitable for confirming the pronunciation of oneself. In order to increase the sound function, the microphone is made larger, and the microphone is often separated so that it can be aimed at the sound collection target. Each of them is made for the purpose of collecting a sound source different from that of the self, rather than a device for listening to the pronunciation of the self. It's quite commonplace. This is because the pronunciation of the self is large enough to be heard by the person.

[0003]

[Problems to be solved by the device]

 However, in language training, it is absolutely necessary to first utter a speech and then listen to and confirm it with one's own ear. Moreover, with the advent of a compact tape recorder that is convenient to carry, language learning itself is not practiced only in a quiet space. For example, on a commuter train. In such a general noise environment, a device that collects only the sound of oneself is desired to be easily detachable without causing any inconvenience to the wearer even when wearing the body.

[0004]

[Means for Solving the Problems]

 The present invention incorporates a battery, an amplifier, etc. in an earphone, attaches a small super-directional microphone to the tip of a flexible tube that is flexibly bent directly connected to the earphone, and integrates them into the ear shell with one ear hook. It is a device to be attached to.

[0005]

[Action]

 Since the sound collection target was limited to the self-pronunciation, the amplifier circuit and the main unit were made extremely compact and lightweight, freeing from the trouble and inconvenience of mounting, and the mounting and dismounting became extremely easy.

[0006]

[Effect of device]

 (1) Even in a general noise environment, the pronunciation of oneself can be clearly confirmed. (2) Because you hear only your own pronunciation without being disturbed by other sounds, your hearing is concentrated and easier to remember. (3) Although it is small, it has a microphone in its mouth and is forced to speak, so it has a habit of speaking. (4) Since it is a one-ear type, the voice of the teacher from a tape recorder etc. can be input to the other ear and compared with the pronunciation of oneself. (5) Since it is not a completely sealed headphone, the sense of direction is not lost even when outdoors, and danger signals can be heard and it is safe. (6) There is no feeling of discomfort when mounted, and it is extremely easy to put on and take off. As described above, the present invention enables extremely easy and full-fledged language learning even in a general noise environment such as outdoors or in a car.
