Abstract

Tone control circuit includes: capacitance resistance circuit; the resistance capacitance circuit which is connected with said capacitance resistance circuit; and variable resistance which is connected with resistance capacitance circuit and capacitance resistance circuit or connection point of two circuits. So, when the voice is output, under the condition of unchanging sensuous volume, the toneis easily to be controlled in high frequency and low frequency.

Description

technical field [0001] The invention relates to a tone control circuit for hearing aids, audio equipment and the like. Background technique [0002] Conventional tone control circuits for hearing aids, including control circuits at high and low frequencies, are provided by, for example, Figure 7 The capacitor-resistor circuit shown in and the resistor-capacitor circuit are controlled independently. [0003] Therefore, control by the user of the hearing aid is difficult since the control point is divided by two points. Furthermore, since the loudness (sensuous volume) changes when sound is output even if it is controlled, the user has to control the tone and the volume at the same time, and the control by the user is difficult. Therefore, users always request adjustments from doctors, specialists. Therefore, it is difficult for the user to maintain a comfortable state to use. Contents of the invention [0004] Accordingly, an object of the present invention is to provid...
