Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker for sitting on a chair having an exciter and a drive circuit and watching a movie program, a video or the like on a home television receiver.
It is equipped with a subwoofer and an exciter, and by adding the vibration of the normal range sound and the low range sound that can be heard from the ear generated by the drive circuit and the vibration below the audio frequency sound by another exciter dedicated to the ultra low range. The present invention relates to an AV viewing chair which is transmitted to a listener to further enhance the realism of the ultra-low range.

2. Description of the Related Art In an audio device installed in a movie theater or the like, in order to bring out a realistic sensation, the audience's consciousness is focused on the screen, and in particular, the ultra-low range that trembles is felt. The audio device, which was produced with the main purpose of making it happen, is attached to a normal projection device, so that the audience can be fully empathized with the screen and the effect of watching the movie can be raised and satisfied. ing. In order to realize the conditions of these movies as much as possible, the sound device attached to the normal projection device has a speaker around the projection screen and a subwoofer such as a combination horn type dedicated to bass reproduction. It is installed separately and is paying special attention to super bass reproduction. In this way, in a movie theater with a large space, the resonance of the air in the hall is skillfully used to make it possible to express the ultra-low range relatively easily and with good radiation efficiency. In order to obtain a sense of realism, unless the sound is replayed at a remarkably large bass volume, it is not possible to obtain a super-bass sensation that trembles. Also, in order to realize such an acoustic sensation of a movie theater at home, when the sound is reproduced at a high volume level, the sound conversion efficiency is remarkably deteriorated, and it is completely allowable from the viewpoint of maintaining the surrounding home environment and cost. is not. Therefore, it is not suitable for the listener to enjoy the sound of movies and plays (video) at home.

[0003]

That is, in the conventional home AV viewing chair of this type, a speaker for reproducing the normal range of the sound reproducing apparatus installed in a normal home TV receiver is not enough. Since the reproduction of the low range is not sufficient, only the presence of the lean low range can be obtained, so only a woofer for reinforcing the low range is added to reinforce it. However, increasing the volume in the low frequency range to increase the playback level by emphasizing only the realism is not suitable for general household use in the surrounding environment. Must be
There was a problem that it was not possible to obtain the presence of super bass.

As a prior art considered to make up for such a conventional defect, for example, Japanese Patent Application No. 2000 by the present applicant.
340207 “Sensory-type acoustic vibration sensing device” (hereinafter abbreviated as sensible device). In this experience device, a speaker that reproduces a normal reproduction range is attached in front of the left and right armrests of a chair, and a shaker is attached to the armrest of the chair to assist the low range reproduction of the speaker. That is, in order to enhance the whole range that can be heard from the hearing of the speaker of the normal reproduction range attached to the back of the chair or the tip of the armrest, and the low range outside that range,
A shaker attached to the position of the palm placed on the armrest, which gives low range vibration stimulation through the "pot" of the palm, is attached to the armrest in an auxiliary combination outside the reproduction range of the speaker. Therefore, it is intended that the presence is not revealed. In other words, the low-pitched part outside the reproduced sound range of the speaker is simply converted into vibration and transmitted to the human body by using the “pot”. Therefore, the conventional sensation device only adds such a loudspeaker and an exciter that generates vibration in the low range of the speaker, so that not only the unbalanced reproduction range lacking the low range can be covered, With a shaker attached to the back of the chair, I was not able to concentrate my attention on the screen in front because I was worried about the vibration.

As is apparent from the above description, according to the present invention, the normal reproduction range (15,000H) can be obtained from the speaker attached to the frontmost of the left and right armrests of the chair.
(z to 200 Hz) can be heard directly from the ear, and a subwoofer that reinforces a low-pitched part lower than the speaker in the space below the seat of the chair
40 of a shaker that covers a low frequency range of 0 Hz to 40 Hz and is attached to the left and right armrests of a chair behind the speakers in the horizontal direction so as to be in close contact with the palm.
Vibrations of Hz-5 Hz can be stimulated by the listener through the peripheral nerves of the fingertips of the hand. Furthermore, vibrations in a frequency range of 40 Hz to 5 Hz of a plurality of exciters attached to the calf of the chair in phase with the longitudinal direction of the leg are distributed to the calf of the leg. Can be stimulated.

As described above, the vibration exciter is installed at a position in front of the human body so that the consciousness can be concentrated on the front surface of the human body. It is placed near the peripheral nerves of the calves and fingers of the fingers and legs so that even small vibrations can be felt as super low frequency vibrations. The transmitted stimulus is transmitted to the human body as a sound vibration, superposed on the blood flow in the vein, and propagated throughout the body. Only the ultra-low sound is felt by the listener because it can be converted into vibration by the vibration exciter, so even if the low-frequency vibration at an excessive volume level is not radiated, the entire environment will tremble without being bothered by the surrounding environment. You can get a feeling. Therefore, the listener can hear the reproduced sound of the normal speaker and the subwoofer from his / her ears by sitting in the AV viewing chair of the present invention, and can feel the vibration in the ultra-low range lower than that from the exciter. Sit in an AV viewing chair that is driven by a small output amplifier for home use, and in the atmosphere similar to that of a movie theater, theater, hall, etc. It is possible to exhibit an excellent effect that can be experienced.
