Title: Acoustic device
Inventor: MITSUHASHI MAKIKO
IPC: H04R29/00
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To monitor the input and output of an acoustic device without requiring any complicated excessive wiring. SOLUTION: An acoustic device is provided with a signal processing means A4 which performs signal processing for sound outputs, another signal processing means B7 which has the same signal processing function as the processing means A has and performs signal processing for sound outputs for monitor, and a control means 10 which controls the processing means A and B. The device inputs a sound input 2 to the processing means A and B by branching the input 2 and, when the sound output 6 of the device is monitored, causes the processing means B to make the same signal processing as that performed by the processing means A. When the sound input 2 is monitored, the processing means B is controlled so that the signal processing function of the means B may not be made effective.  Since a sound signal for monitoring the sound output or sound input is outputted from a monitor outputting means which outputs the signal of the processing means B in accordance with the control to the means B, the sound output and sound input can be monitored without requiring many wiring.
