In the conventional large-in-class Cusby force, the heat generated from the voice coil is conductively transmitted to the air in contact with the voice coil, and transmitted to the poles and plates positioned with a gap between the inside and the outside of the voice coil by heat radiation. The heat received from the pole and the plate is transmitted to the entire magnetic circuit, and is dissipated to the outside of the speaker by heat radiation from the entire outer surface of the magnetic circuit and air heat conduction. In the case of a 4 Ik large input speaker, the voice coil is often moved up and down, so the part K or l-deviated from the magnetic circuit; In some cases, since the iim of the voice coil is excessively raised to cause rare short or deformation, the performance is deteriorated, so that heat radiation from the voice coil is promoted. In the process of the first example shown in 1'-, the upper surface of the pole 1 is made of copper, aluminum or the like, and the non-magnetic heat dissipating link (or cylinder) 2 is fixed so that radiant heat from the top of the voice coil 3 is also received. In the well ring 2 which prevents the red heat of the voice coil 3 in such a manner that the eddy current is generated by the electromagnetic induction due to the change of the current flowing through the voice coil 3, the characteristic is deteriorated. The present invention is a speaker having a heat dissipating ring (or / ring) for the purpose of eliminating the change in sound quality as well as 13-05-2019 1 dissipating heat. An embodiment of the invention will now be described with reference to the drawings. As shown in FIG. 2 and FIG. 2 ′, this embodiment of the present invention uses a ql / heat ring 2 ′ cut at the upper surface of the ball 1 with a slit (gap) 4 and a voice coil on the upper edge thereof. It is a speaker that is fixed to three heights with a height that is high enough to correspond to the upper edge of 3. In FIG. 2, a symbol 5 indicates a magnet, a top plate 6 is a yoke, and 7 indicates a yoke. If a current having a change is sent to the voice coil 3, the voice coil 3 generates heat and generates a magnetic field line having a change parallel to the axis in the house as a solenoid. -141 The heat from the voice coil 3 is partially conducted to the air and transmitted from the convection VC of the air, and the others are correspondingly mounted heat dissipating ring 2 ', pole 1. Top plate 5F (radiatively transmitted and dissipated from the outside of the speaker by radiation, conduction, and convection from the outer surface of the aeration (b) path metal. In addition, the magnetic lines of force having a change parallel to the axis generated at the tangent of the voice coil 3 are balls 1. A strong current between the top plate 6 acts on the core 6 and the voice coil 3 vibrates up and down, and the radiating ring 2 [a current flows in a direction perpendicular to the axis and prevents movement of the voice coil 3 (up and down movement) However, since the flow is blocked by the slit 4, the vertical movement of the voice coil 3 is smoothly performed. According to the above-mentioned persimmon pick-up 's K, providing a ring (or cylinder) K slit to prevent overheating due to heat generation from the voice coil on page 4 K, no eddy current is generated, and the characteristics deteriorate Not cause 13-05-2019 2
