ー。Internal microphone, jack for external microphone,
A tape recorder equipped with an internal speaker and an external speaker jack includes a preamplifier circuit that amplifies a signal obtained from a microphone, and a main circuit that applies the signal amplified by the preamplifier circuit and further amplifies the signal. It consists of an amplifier circuit, a selection switch for switching between tape recorder use and interphone use, and a non-locking conversation switch that is switched during conversation operation, and when the selection switch is on the interphone use side, the conversation switch is switched on. An intercom function characterized in that the input signal to the preamplifier circuit is switched from the external microphone to the signal from the internal microphone by switching, and the output signal of the main amplifier circuit is applied from the internal speaker to the external speaker. Tape recorder.
