Abstract

PURPOSE:To radiate effectively heat and to assemble a large output amplifier circuit in a small speaker cabinet by equipping a bass-reflex board that is performed with a heat conductive material to a speaker cabinet and attaching the exothermic parts of the amplifier circuit to a part of the bass-reflex board. CONSTITUTION:As for the heat value of the exothermic part 10, in the inner surface of a the bass-reflex board 5 through the heating part mounting part 5a, the bass-reflex board 5 is effectively cooled and the generated heat is radiated also effectively by the inside and outside air flow of a speaker cabinet 7 that is occurred by the forward and rearward movement of the diaphragm of an woofer 3 that is driven by the amplifier circuit. Also, so that this air flow is proportioned to the output of the amplifier and also nearly proportioned to the heat value of the exothermic part, the heat value of the heating part is proportioned to the radiating value of the bass-reflex board and it is possible to eliminate the variation of the characteristics of the amplifier by the change of temperature of the heating part.

Next, the operation of the configuration of this embodiment will be explained. First, the amount of heat from the heat generating component 1o is transmitted to the bass reflex port 6 through the heat generating component mounting portion Sa of the bass reflex port. On the inner surface of the bass reflex port 6, there is an air flow inside and outside the speaker cabinet 7 caused by the back and forth movement of the diaphragm of the woofer 3 driven by the amplifier circuit. cooled down. Therefore, the heat generated by the heat generating component 10 is effectively radiated.

In addition, this air flow is proportional to the back and forth movement of the woofer's diaphragm, that is, the output of the amplifier, and the output of general amplifiers, except for amplifiers with Mu-class operation, and the amount of heat generated by heat-generating components are almost proportional. As a result, the amount of heat generated by the heat-generating components and the amount of heat dissipated by the bass reflex port are proportional, and the temperature of the heat-generating components becomes constant, eliminating changes in the characteristics of the amplifier due to changes in the temperature of the heat-generating components. . If a filter or the like is provided in the bass reflex port 6 to increase the surface area, the cooling effect can be further improved.
