Description

[0014]
[Means for Solving the Problems]
The invention according to claim 1 of the present application is a chair with a speaker, comprising: a seat, a backrest pivotally supported to the rear of the seat, inclination angle changing means for changing an inclination angle of the backrest, and the backrest an angle detector for detecting the angle of inclination of the parts, and amplifier for outputting to the speaker to amplify the audio signal, the amplification degree and the operation of outputting an instruction signal for controlling an inclination angle of the backrest portion of the audio signal by the amplification unit Part, the clock part outputting time information, the inclination angle of the backrest detected by the angle detection part, and the inclination information of the backrest below a predetermined angle based on the time information output by the clock part be characterized in that it comprises a control unit for controlling said operating portion within predetermined time in a state to stop the amplification when no outputs an instruction signal audio signal by the amplification unit .

[0015]
The invention according to claim 2 of the present application is the speaker device according to claim 1 , characterized by comprising a time setting unit for setting the predetermined time .

[0016]
According to a third aspect of the present invention, there is provided a speaker-equipped chair including a seat, a backrest pivotally supported behind the seat, an inclination angle changing means for changing an inclination angle of the backrest, and the backrest. Operation for outputting an instruction signal for controlling the amplification degree of the audio signal by the amplification unit and the inclination angle of the backrest unit, an angle detection unit that detects the inclination angle of the unit, an amplification unit that amplifies the audio signal and outputs it to a speaker Part, clock part outputting time information, time setting part setting the first time and second time, inclination angle of the backrest detected by the angle detection part and time output by the clock part When the operation unit does not output an instruction signal within a first time set by the time setting unit in a state where the inclination angle of the backrest is less than or equal to a predetermined angle based on the information Characterized in that it comprises a control unit for performing a second time control for stopping the amplification of audio signals set by the time setting unit begins to reduce the amplification degree of Dio signal.

[0017]
