DETAILED DESCRIPTION OF THE INVENTION This invention relates to a magnetic circuit for a
speaker, and more particularly: The present invention relates to a speaker magnetic circuit
improved in the cooling at of a voice coil under magnetic breakdown. In order to improve the
magnetic field of the speaker, which has not yet been known, a setter pole is placed on a steel
camp and a barge, and a Nog held on a center pole to improve the heat-effective rice, a voice coil
am 6-, t is intended to reduce the current distortion of the magnetic path, but when the steel cap
is rolled, the axiom of III of this cap is (The diameter of the 4-pole QcX center pole should not be
reduced. (Because of .sigma., The air gap will become thick as a result. In addition, current
distortion reduction due to steel camping is not so effective in the low frequency range. In the
latter case of a voice coil that generates heat (near 9 aaU, it is aimed at a low temperature metal,
but it is aimed at low temperature, but in the case of nog deposition with health, the positioning
of <is 1-etc. had ffl. Therefore, in this invention, the former and the latter magnetic paths are
combined to improve the flow distortion (and the heat dissipation excellent magnetic Ig circuit t),
therefore, the upper and lower four parts of the center pole A step is provided with a depth
equivalent to the thickness of the FR1 jivc steel cap and heat dissipation lingo, and these caps
and others do not project into the air gear tub, and positioning is reliably performed.
Furthermore, the magnetic 1g circuit excellent in heat dissipation It is In the following, the
description will be made old in the drawing attached with this 4 chestnut spoof + # 1iea. First of

Therefore, according to the magnetic circuit for a speaker of this examination, since the Zeiss coil
6v is heated close to the device which has come close to it, the heat is conducted and cooled, and
the voice coil is cooled. As a result of the input resistance can be thick (. In addition, there is a
heat release ring / J, a bank of rcllN, and a long turnout ksVCa * @ tt, a tco, and this all should be
inserted into the 趨 st- of each ring, and the air gear lug should be extended from the skin (The
