ACOUSTIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide acoustic equipment which improves acoustic properties, in particular, a high-pitched transient property by increasing a signal transmission rate per se.SOLUTION: In each of electronic components such as resistors and capacitors of a rectifying/smoothing circuit 1, an amplifier circuit 2 and an output circuit, property improving elements A and B are provided in parallel. Thus, when an alternating current resulting from transforming a commercial alternating current on which a high-order higher harmonic wave component (high frequency component) is superimposed or a pulse current derived therefrom is to be transmitted in a resistor R1 that is an electronic component in a power supply line and the property improving element A in parallel with the resistor R1, in the alternating current or pulse current resulting from transforming the commercial alternating current on which the high frequency component is superimposed, only the high frequency component is transmitted in the property improving element A faster than the resistor R1 that is a normal electronic component in parallel with the property improving element A by a high-speed electric field transmission action of the property improving element A. Only the high-speed transmitted high frequency component of the alternating current or the pulse current resulting from transforming the commercial alternating current flows to a ground and is eliminated by the property improving element A of the same discharge voltage provided in parallel with a capacitor C1 that is a normal electronic component between a post-stage power supply line and the ground, and a high-pitched transient property is improved.
