Acoustic control system for electronic musical instrument
First Claim
1. An acoustic control system for an electronic musical instrument, comprising:
- a musical instrument body having a first speaker;
a second speaker removable from said musical instrument body;
designation means for designating one of a first speaker-use mode for using said first speaker alone and a both speaker-use mode for using both said first speaker and said second speaker, as a speaker use mode;
storage means for storing first and second acoustic-characterizing factors different from each other, for use in setting acoustic characteristics in the first speaker-use mode and the both speaker-use mode, respectively;
reading means for reading one of the first and second acoustic-characterizing factors, the one corresponding to the speaker use mode designated by said designation means; and
musical tone signal-generating means for generating a musical tone signal to be reproduced through said first speaker or both said first speaker and said second speaker, based on the read one of the first and second acoustic-characterizing factors.

Abstract
An acoustic control system for an electronic musical instrument, which can obtain optimal acoustic characteristics irrespective of whether or not a low range speaker is attached to a body thereof. A piano body has high range and mid range speakers. A low range speaker is removable from the body. A stand-excluding switch designates a first speaker-use mode for using the high range and mid range speakers alone, and a stand-including switch designates a both speaker-use mode for using both the high range and mid range speakers and the low range speaker. A ROM stores stand-excluding and stand-including factors for setting acoustic characteristics in the two modes, respectively. A CPU reads one of the factors, which corresponds to the mode designated by the stand-excluding or stand-including switch. A tone generator circuit generates a musical tone signal to be reproduced in one of the modes, based on the read factor.
