Description

A member for a chair equipped with a multi-channel sound system and a chair including the same

The present invention relates to a member for a chair equipped with a multi-channel sound system and a chair including the same, and more particularly, it is possible to provide a spatial or three-dimensional effect to a user seated in a chair by sound output from a plurality of channels. It relates to a member for a chair equipped with a multi-channel sound system and a chair including the same.

In general, a speaker used in connection with a computer produces sound by converting a current flowing through an electric wire into an electric signal and a vibration signal and vibrating it with a vibrating unit.

For example, when watching a movie or playing a game through a computer, the user sits in a chair where the computer monitor can be viewed and watches the image reflected on the computer screen with his/her eyes, and at the same time, an electric signal is transmitted and the speaker vibrates. Vibration corresponding to the image is transmitted to the user's ear due to the shaking, so that the user can hear the sound.

In particular, in the case of a multi-channel sound system having a plurality of such speakers, there is an advantage that a user can more precisely experience the direction and magnitude of sound in an image.

However, in order to implement such a multi-channel sound system, it is necessary to provide each speaker on the top, bottom of a desk, or the back of a chair, and it can be said that the space is limited in that a plurality of speakers must all be electrically connected.

In addition, even if a multi-channel sound system is implemented by arranging a plurality of speakers, there is a problem that the position of the chair is changed or various physical interferences existing between the user and the speaker sitting in the chair may exist.

As a related prior art, there is Korean Patent Application No. 10-2014-0138848, which relates to a chair-type massage device having a multi-channel sound system.

According to the prior art, in the chair-type massage device including the seat part, the footrest part, the backrest part, and the armrest part, the initial position and the protruding listening position are disposed at the front end of the seat part and inserted in response to a seating or leaving operation of the person to be treated A center speaker moved between positions, a pair of front speakers respectively disposed at the front end of the left and right armrests of the seat unit and moved between an initial position inserted and a protruding listening position in response to a seating or leaving operation of a person to be treated; A pair of rare speakers respectively disposed on the upper left and right sides of the backrest and a multi-channel audio output unit for applying audio signals corresponding to the plurality of speakers, respectively, wherein the audio output unit is provided on the seat in a state in which the patient is seated The body type of the subject is detected, the listening origin of the subject is calculated based on the detected body shape information, the distance between the calculated listening origin and each speaker is calculated, and applied to each speaker based on the calculated distance Disclosed is a chair-type massage device that generates three-dimensional sound by adjusting a volume level or a time delay amount of an audio signal.

However, even with the chair-type massage device, the position where the speaker for outputting sound is provided is fixed to the upper left and right sides of the upper back of the chair-type massage device and the front end of the left and right armrests of the seat part, so more precise adjustment of the speaker is impossible There is a limit to

Therefore, the chair-type massage device simply satisfies 5.1 channels only in the number of speakers, and accordingly, it is difficult to see that the direction and size of sound in the image can be transmitted more vividly to the user.
