    Default Audio sounds

    Hi,

    I'm making a toy and I need at least four different sounds. I looked at a piezo buzzer and they are expensive to put four on the board. I'm not using a PIC so I don't have the option of doing software routines. My thought at this point is to use a 555 with one piezo buzzer to try and make different sounds by adjusting the timing. Is this a good idea? Is there a chip out there that can help me do what I need to do? Maybe get an inexpensive PIC with PWM or DTMF tones? Any advice is greatly appreciated.

    Thanks,

    Chris
