Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television set, and more particularly, to a television set which can be viewed in an optimum state for both a normal person and a hearing-impaired person. is there.

[0002]

2. Description of the Related Art In general, the range of the volume of sound that can be heard by a hearing-impaired person is considerably narrower than that of a healthy person. If it is too small, it cannot be heard, and if it is too large, the sound reverberates, making it difficult to hear. Therefore, when a person with a hearing loss and a normal person watch TV together, if the volume suitable for a person with a hearing loss is set, it is too low for a person with a hearing loss, and if the volume is increased according to the person with a hearing loss, it is too high for a person with a hearing loss. Yes, it will bother the neighborhood.

When an earphone is connected to an earphone terminal for a hearing-impaired person in consideration of troubles in the neighborhood, no sound is produced from the speaker and a normal person cannot hear the sound.
And if there is one person with hearing loss, even if they try to connect the earphones to the earphone terminal and listen to the sound, the sound output from the earphones is output with the frequency characteristics for the healthy person, so even if the volume is increased, the hearing loss is difficult. It is often difficult for people to hear. This is also related to the fact that the earphones attached to the TV are air-conducting type and are not suitable for persons with hearing loss due to a conduction system disorder such as the eardrum or ossicles.

As shown in each drawing, the sound processing unit of the television main body has at least one of a sound processing unit A for a hearing-impaired person and an infrared transmission unit C for a hearing-impaired person in addition to an existing sound processing unit A included in a general TV. It is made by adding.

The existing audio processing section A includes a volume controller 1, an audio amplifier 2, a speaker 3, and an earphone jack 4.
Consists of. Further, the audio processing unit B for the hearing impaired includes a frequency characteristic adjusting device 5 for the hearing impaired, a volume adjuster 6 for the hearing impaired, an audio amplifier 7 for the bone conduction speaker, and an earphone jack 8 for the hearing impaired (FIGS. 1 and 2). Infrared transmitter C for hearing-impaired person comprises carrier wave oscillation / frequency modulator 9, infrared LED drive 10 and infrared LED 11 (see FIG. 3).
The video signal is processed by the video processing unit, and the video is output by the cathode ray tube of the television body.

Next, the audio processing of the television set according to the present invention will be described with reference to FIGS. First, a tuner selects a television signal to be received from an RF signal received by an antenna, amplifies and detects a voice signal by a voice intermediate frequency amplification / voice detector 20, and converts it into voice. Then, this voice is output to the voice processing unit A and the voice processing unit B for the hearing impaired person, and when the external transmission means is provided, it is further output to the infrared LED 11 of the infrared transmission section C for the hearing impaired person (FIG. 2).
