Description

Hearing impaired training device for the hearing impaired by bone conduction hearing

The present invention uses the bone conduction hearing, such as bone conduction telephones, bone conduction headphones and spinal vibration device that the hearing impaired person with a disability in the outer and middle ear, which is a path of air conduction sound, receives an audio signal such as TV, CD or DAT, a cassette and a telephone. The present invention relates to a device for allowing auditory training by the auditory auditory canal by connecting the auditory sound device.

Hearing impaired people communicate with each other through sign language, but there are many difficulties in communicating with normal people. In addition, in the case of acquiring information through the ear such as music or telephone, it is impossible to acquire information. Due to this problem, hearing devices for the hearing impaired have been developed, and these devices are mainly devices using bone conduction hearing. Devices using bone conduction hearing are in a state of practical practical research as well as theoretical research in the field of hearing. Therefore, using these acoustic listening devices for the hearing impaired, it is possible to listen to telephones and listen to music with a normal person. However, most hearing impaired people have a problem that they cannot use these devices using bone conduction hearing because their ability to acquire language is significantly reduced due to poor hearing training after hearing loss.

Meanwhile, research and development of bone conduction phones, bone conduction headphones, and spinal vibration devices are currently in progress.

However, most of the hearing impaired people are hearing impaired in the outer and middle ear, so they rarely hear the sound when using air vibrations caused by air vibration. Therefore, there is almost no effect of the hearing training method using airway hearing. Can be.

Due to these problems, research on the device using bone conduction hearing is ongoing, but it is difficult to see the effect immediately because the meaning of language cannot be understood in the case of hearing impaired.

Therefore, in order to solve this problem, an auditory training device using bone conduction hearing has a very important meaning.

The present invention has been made to solve the above problems, it is possible to perform auditory training in an integrated environment to make actual use of bone conduction hearing devices such as bone conduction telephone, bone conduction headphones and spinal vibration device developed as a single device The purpose is to provide a device.

1 is an overall configuration of the hearing training device for the hearing impaired to which the present invention is applied.

In order to achieve the above object, the hearing training device for the hearing impaired by the bone conduction according to the present invention includes an input unit serving as an external input device and an interface, a processing unit having a function of selecting an input terminal desired by the hearing impaired among various input devices, and External bone also has auditory devices and an output that is a function of selecting such devices.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a block diagram of the hearing training device for the hearing impaired according to the present invention, the overall configuration is shown that the input section, processing section and output section.

As shown in the figure, the input device is applicable to four methods.

The input unit is composed of an external device and an interface part. The external device includes a TV input unit 11, a CD / DAT input unit 12, a cassette input unit 13, and a telephone input unit 14 for providing 44.1 kHZ of audio quality for general home use. This external device is a device used at home everyday, the interface portion is configured to connect the output terminals of the four external devices to the input terminal of the auditory training device by the bone conduction proposed in the present invention. The first variable resistor 15, the second variable resistor 16, and the third variable resistor 17 are used for impedance matching with each input terminal, and the dual telephone external device is provided with a feeding bridge 18. Through the fourth variable resistor (19) through.

The processing device section is composed of three modules. First, the mixer 20, which is a function of selecting one of the devices from the four inputs, the output part selection circuit 21, which selects one of the three output devices, and the power supply circuit 22, which is a power supply part, are provided. Equipped.

The output consists of three devices. Each device is a single device developed as a bone conduction acoustic sound device for the hearing impaired and includes a bone conduction headphone output 23, a bone conduction telephone output 24 and a spinal oscillation device output 25.

The present invention can thus be configured to provide an integrated auditory training environment for devices such as bone conduction phones, bone conduction headphones, and the like using bone conduction hearing.

Therefore, the present invention makes the device of the bone conduction delivery system developed for the hearing impaired into a single integrated environment, and can be used to acquire information about mood sound through training through the device. Therefore, a general telephone call with a normal person, music listening, or the like can be used, and a program such as a TV which is not provided with a sign language service can be used.
