To prevent invasion of the device, prevent malfunction of the device due to pollution, etc., and further, by driving out various insects such as cockroaches from the room where the device is installed, the image of the store where the device is installed is down. It is an object of the present invention to provide a music reproducing device that can prevent the above.

[0011]

In order to achieve this object, the music reproducing apparatus according to claim 1 is an accompaniment reproducing means for outputting an accompaniment of a piece of music and a generating means for generating a sound different from the accompaniment. And a music reproducing device for outputting the sound generated by the accompaniment reproducing means and the generating means, wherein the generating means is configured to generate ultrasonic sound in a range of a predetermined frequency. It is characterized by Therefore, the generation means generates an ultrasonic sound having a frequency that is not suitable for cockroaches and the like, thereby exterminating the cockroaches. Claim 2
