PURPOSE: To provide a communication KARAOKE device which prohibits a writing when it is vibrating and prevents the occurrence of errors. CONSTITUTION: In this communication KARAOKE device, the music data transmitted from a distant KARAOKE database through a communication line are received by a reception controller, are stored in a storage device, read from the device and reproduced into music signals by a music reproducing device to transmit the signals to a speaker 15. A sensor 9 which generates a detected voltage that is proportional to the amount of vibration and a controller 17 which compares a reference voltage and the detected voltage and generates an instruction signal to prohibit the writing of the music data against a storage device 18. If the detected voltage is larger than the reference voltage, the device 17 transmits the instruction signal and prohibits the writing of the music data into the device 18. |
