DETAILED DESCRIPTION OF THE INVENTION The present invention relates to: L7 loudspeakers
for easy heat dissipation of the voice coil. Loud speaker with large input (in two, Joule heat of
voice current ? 2 due to heat generation of voice coil due to C), keep its heat temperature low by
dissipating swiftly its heat quantity ?? 2 However, the requirement is to increase the speaker's
allowable input. Thus, the heat of the voice coil is in the air by taking motion ? 2: release or notfrom the tip of the center hole forming the domain wall close to the voice coil and from the
vicinity of the center hole of the upper plate The air is dissipated into the air from the outside
surface (one contact surface) through the inside of the center pole and the inside of the top plate,
respectively. Among them, above 5. -6? / '/) Part 2 Heat coming into the plate passes through
the contacting magnet, through the outer exposed portion of the magnet and through the
contacting portion with the lower plate, from the outer exposed portion of the lower plate
Medium ? 2 dissipated. However, since the center pole and the upper and lower cylinder plates
are pure iron, the heat conduction rWK 0.14 magnet (ferrite) is lower in O and OO 9 in thermal
conductivity, so the thermal conductivity per unit time 1) The amount of release is very small.
Therefore, the voice coil (two generated heat is not dissipated enough, there is no escape space,
and it is accumulated, so the warmth of the voice coil is high, while the voice coil becomes large
when the input is slightly increased, the voice coil In the case of the adhesive, there was a defect
that the adhesion was broken and separated 1) and burned out C). This invention is an adult
power "scar" which eliminates such a drawback. In the case of the brush 1 shown in Fig. 2, the
shell through hole 2 is formed at the center of the center pole 1 and the inside of the hole 2 2. A
good heat conductor such as copper or aluminum is folded and folded as shown in FIG. 2, and a

heat dissipation material 8 having a large heat radiation area is inserted and filled. The heat
generated by the center pole li is transmitted to the heat dissipation material 3 in the straight
hole ? two central holes 2 (), in the holes 2 (two broken, the cone paper 5 Since the air flow due
to vibration ? 2 (2 is blown out of the hole 2 and thus the cooling effect is extremely large 1)
and hence the temperature rise of the voice coil 4 is held low, the speaker can withstand high
input.
