disadvantage that bamboo sources can not be attached. Furthermore, when these types of
loudspeakers were attached to the speaker enclosure 7's l + 1i- (il, the signals overlapping each
band were radiated with a phase difference (time difference), and it became impossible to align
the phases. Therefore, in order to align the purple phase, the middle f and ilf for the 1st grade of
the steamer was separated from the steamer, or the baffled surface was made to have a step-like
shape. However, such a fx4 combination Vcl''1: near the speaker (K reflection surface is
increased, there is a drawback that 1jll-scratching sound from the speaker and reflected sound
from the reflection surface interfere with each other. Therefore, the present inventor removes the
above-mentioned lack of immersion so as to eliminate the phase difference when radiating the
honors overlapping the respective f sources, and without using the diffracted main body by the -

that rapid motion-type motional feedback can be applied, and the shoulder characteristics,
distortion and non-linear tampering near the lowest collusion-periphery IM number can be
applied. Fig. 3 is a partial cross-sectional view of the medium f and high f sliders that can be
easily designed. In addition, the cedar-like shape of the vibrating body (1) is a middle nine
cylindrical shape, and the detection coil is not branched. The detection coil is provided not only
for the low frequency slider but also for at least one of the other contracts (j ′ ′) for
