examples of the power to let a plurality of speakers go inside. 1) By radiating a plurality of
speakers in the inner part of the sardine, it is possible to widen the directivity of the sound. 2) It
is possible to take out the input with a large resistance, it becomes possible to reproduce the loud
sound, it is also advantageous for low piece regeneration. 1−? Rod 6) By changing the wiring
method, it becomes easy to set arbitrary speaker impedance. 1), the effect is great, the sound
diffuses well, the sound reaches every corner of the room, and comfortable sound quality and
sound field can be obtained also on the music reshuffle. It is also possible to play stereo with one
unit. Conditions for a rapidly loudspeaker are that it is a full range of compact high fingering
