摘要: A method of limiting the maximum permitted sound volume in an earphone, a headset or like, includes step that size driving signal for earphone is sensed. The has voltage less than approx. 0.7 V. If exceeds certain level, part shunted past earphone. second diverted. Either diverted increased and controls shunt device by which first it supplied to unit with detector device. sensitive work at voltages below An like above-mentioned comprises whose current source
