PURPOSE: To receive a call by cutting a call tone at a place where the call tone troubles others by providing a motor and a switch in a receiver. CONSTITUTION: A battery type power source 1 is connected to the receiver 2 with a power cord 1a, and the motor 3 which generates oscillation is connected to the receiver with a motor cord 3a in a power source A. Moreover, the switch 4 is connected to the receiver 2 with a switch cord 2a so as to easily switch the presence/absence of oscillation. In reception, the call is received by the receiver 2, and the motor 3 is rotated, and the oscillation occurs, which informs the call from an opponent. Transmission is performed similarly by a conventional function. Therefore, the reception can be performed by cutting the call tone at a place where the call tone torubles others such as in a conference or train, etc. The reception can be performed by the oscillation by using this oscillatory telephone calling device even at a place where the call tone is hard to hear due to a noise. |
