PURPOSE:To provide a speaker for improving the sound pressure level in a high tone range without degrading the sound quality in low to middle tone ranges. CONSTITUTION:By providing plural speaker units 3a and 3b, a coil 4 through which the respective speaker units are series connected and capacitors 5b and 5a for bypass-connecting the respective speaker units to the side of input terminals 1 and 2, since the respective speaker units are series connected in the low to middle tone ranges and are parallelly connected in the high tone range viewing from the side of the input terminals, a signal current in the speaker units becomes large in the high tone range and the sound pressure level of the high tone range is improved. |
