Abstract

(57) [Summary] PROBLEM TO BE SOLVED: A speaker with an audio frequency variable device comprising a speaker and an audio frequency variable device capable of changing an audio frequency band, and an amplifier for amplifying an audio signal, which can be easily connected to a general television and can be listened to. You can easily set the frequency band that suits your ears and the volume that will not bother others. SOLUTION: A variable device capable of changing an audio frequency band of an audio signal from a television and a speaker assembly including an amplifier can be easily installed and operated, and a volume which does not bother others can be easily set.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to external speakers for televisions. The present invention is a speaker that can freely output sound that suits the hearing of various people. It is a speaker with an audio frequency variable device that can be created.

[0002]

2. Description of the Related Art Conventionally, people who have difficulty hearing have a hard time hearing the sound when trying to watch TV. I am listening to it while connected to a stereo.

[0003]

[Problems to be solved by the invention]

[0004] When trying to listen to the television at a high volume, the volume of the volume is too high for those who are watching the TV together in the vicinity.

In order to connect the audio output of a television to a stereo or the like for listening, the television and the stereo must be close to each other, and a television having no audio output cannot be connected to the stereo or the like. The combination shown in Fig. 4 is impossible for elderly people and those who are not familiar with machine operation.

[0006]

[Means for Solving the Problems]

 The present invention intends to solve the above problems in the conventional method by the present invention. The present invention is a speaker with an audio frequency variable device that can change the audio frequency band, an amplifier that amplifies the voice signal, and an input terminal for inputting the audio signal. .

[0007] The audio frequency variable device can easily set a frequency band suitable for a listener's ear and a volume that does not bother others.

There is no need for a large device such as a stereo.

Since the operation part and the speaker part are integrated, the operation can be performed at a place where the user wants to listen.

[0010]

EXAMPLES The present invention will be described with reference to examples. Embodiment An embodiment will be described with reference to the drawings. Insert one end of the supplied phone cord a into the earphone or headphone terminal e of the TV, and the other end into the phone input terminal on the back of the speaker body.

Next, a battery is placed in a battery case. Also, insert the attached power cord instead of the battery and turn on the power switch. After that, move the knob of the audio frequency variable volume so that you can hear it easily.

[0012] A pin code c can be connected to the audio input terminal of the speaker body from the audio output terminal of the television instead of the telephone terminal of the television for listening.

Effects of the Invention You can listen at a volume that does not bother others. 2. It can be adapted to various people's hearing. 3. You can operate it where you want to listen.
