Abstract: An elastic body 3 includes through holes 32 connecting upper and lower surfaces thereof. Therefore, compared with a case where the through holes 32 are not formed, a sound produced due to vibration of the elastic body 3 at a time of a percussion to the head 1 can be reduced effectively. Meanwhile, in regions where the through holes 32 are not formed, the vibration at the time of the percussion to the head 1 is propagated to the support part 20 via the elastic body 3 itself. Accordingly, the vibration at the time of the percussion to the head 1 can be propagated to the head sensor S1 via the support part 20. Accordingly, the percussion to the head 1 can be accurately detected, while the percussion sound at the time of the percussion to the head 1 can be reduced.

Abstract: A sensor for vibration detection is not installed to a second frame 301b, and an upper surface of the second frame 301b is a non-percussion surface not assumed to receive a percussion. Since the second frame 301b is elastically supported by the first frame 301a via the elastic bodies 309a to 309c, at the time of a percussion to a head 202 or a cover 206, the elastic bodies 309a to 309c can attenuate the vibration propagated from the first frame 301a to the second frame 301b. Thus, since the noise produced due to the vibration of the second frame 301b can be suppressed, the performer is allowed a favorable feeling of performance.

Abstract: The invention enables FAX signals to be transmitted transparently in a CDMA-WLL system. Data of many FAX signal waveforms are prestored in a vocoder in a terminal, and when a FAX signal is input, the index value of the waveform data having the smallest difference relative to the input signal is transmitted out.
