PROBLEM TO BE SOLVED: To increase an output of a speaker more than the performance of the single speaker. SOLUTION: An upper circumferential edge of a cone 3b of a tweeter 3 contained in a 2nd speaker mount 10 is fitted to a connection part 11a formed by folding back part of a circumferential edge of a speaker net 11 fitted to an upper case 1a of a music instrument main body 1. Thus, when the tweeter 3 emits sound, the vibration of the tweeter 3 is transferred to the speaker net 11 via the connection part 11a, thereby vibrating the speaker net 11 and then the sound of the tweeter 3 is enhanced and then an output of the tweeter 3 is increased more than the performance of the single tweeter 3. |
