Abstract
PURPOSE: To check the disconnection of a wire of the transducer without being influenced by the position of volume by connecting the output end of the amplifier to a transducer to be inspected through a high impedance element and a sound volume adjusting volume.
CONSTITUTION: A test signal is input from an input end 1, and output to a test terminal 4 through an amplifier 2, a high impedance element 3. The test terminal 4 is connected to a speaker as a transducer through a capacitor 5, and a sound volume adjusting volume 6. The disconnected wire checking signal is fed and the presence of the wire disconnection is obtained from a terminal 13. When an auido signal is transmitted to the speaker 7, the switch is closed and the impedance is by-passed.
