Sound apparatus

Abstract

To provide a simple sound apparatus in which an excellent sound effect can always be obtained. There are provided a seat portion 110 having a backrest portion 113 and a stool portion 114, a pair of closed-loop-shaped main frames 120 respectively attached to both side edges of the seat portion, and a sub-frame 130 including a vibrating unit 150 and connected to at least one of the main frames, and vibration generated from the vibrating unit is transmitted to the seat portion through at least one of the main frames.

Description

[0001] A sound apparatus characterized by comprising:[0002] a seat portion having a backrest portion and a stool portion;[0003] a pair of closed-loop-shaped main frames respectively attached to both side edges of the seat portion; and[0004] a sub-frame including a vibrating unit and connected to at least one of the main frames,[0005] wherein vibration generated from the vibrating unit is transmitted to the seat portion through at least one of the main frames.[0006] A sound apparatus according to claim 1, wherein the main frames comprise armrest frames attached to both side edges of the backrest portion, ground frames, front leg frames attached to both side edges of the stool portion and connected to one end of the armrest frames and one end of the ground frames, and rear leg frames connected to the other end of the armrest frames and the other end of the ground frames, and[0007] wherein one end of the sub-frame is connected to the front leg frame and the other end is connected to th...

AI Technical Summary

Benefits of technology

[0022] According to the above structure, the vibrating unit is fixed to the sub-frame connected to the main frame, the user can easily obtain the best listening position by the seat portion, and the position is fixed, so that it becomes unnecessary to carefully adjust the position of the speaker and the position of the user in order to produce a stereo effect of sound and a 3D effect, and sound image orientation recorded at the time of content production can be accurately and easily reproduced.

Problems solved by technology

On this account, since the vibration is diffused to all the body of the user, there is a problem that the vibration is transmitted to unnecessary parts other than the part of the body to which the vibration is to be originally given, and an unpleasant feeling is given to the user.

Besides, since the transmission state of the vibration is varied by a slight change of contact pressure between the body of the user and the vibrating plate, there is a problem that it is difficult to always obtain an excellent sound effect.

Besides, in the foregoing conventional latter chair type sound apparatus in which the vibrating unit is integrated, it is necessary that the inside of the sitting portion and the backrest portion constituting the chair is formed to be hollow and the opening portion is provided in the sitting portion and the backrest portion, there is a problem that the manufacture requires labor and the manufacturing cost becomes high.

Further, in both the sound apparatuses, since the speakers are disposed at both sides of both ears of the user, there is a problem that in the case where an image apparatus is provided in front of the chair, and a picture image and a sound synchronized with that are appreciated, an uncomfortable feeling is given to the user.

This is because there occurs such a disadvantage that if the band of the vibration is higher than 135 Hz, a sound band is reproduced so that a voice is heard from under the seat portion 114.
