ACOUSTIC-ELECTRIC TRANSDUCER WITH CHANGEOVER SWITCH FOR MUTE STATE

An acoustic-electric transducer 1 includes a connection part 13 that has a first connection point 131 able to contact a first contact A in a terminal 2 for processing the electrical signal, and a second connection point 132 able to contact a second contact B having a potential lower than the potential of the first contact A, a microphone 101 that transduces a sound inputted from an external source into an electrical signal, a changeover switch 11 that switches between a non-mute state where the electrical signal is outputted to the terminal 2 and a mute state where the electrical signal is not outputted to the terminal 2, and a current control circuit 14 that makes a current flow between the first contact A and the second contact B until a predetermined time passes from the time when the connection part 13 is connected to the terminal 2 and reduces the current flowing between the first contact A and the second contact B after the predetermined time passes, the current control circuit 14 being provided between the changeover switch 11 and the connection part 13.
