Title: Cordless telephone set
Inventor: KONO HIROKUNI
IPC: H04M1/00
Filed: 1990-02-06
Abstract: PURPOSE:To ring a bell with a small tone volume not giving any displeasure to the user by reducing the bell tone volume through the detection of proximity or contact of a slave set to the user. CONSTITUTION:A proximity detection means 10 detects proximity or contact of the user such as grip of a slave set 6 and sends a proximity detection signal to a slave set control means 9. The slave set control means 9 sends a gain suppression signal to an amplifier control means 13 when a proximity detection signal from the proximity detection means 10 is received in the reception of a bell data. The amplifier control means 13 decreases the amplification factor to a predetermined low value from a specified value in response to a gain suppression signal thereby suppressing the level of a bell tone to a proper low value.

Abstract: PURPOSE: To achieve a large output without distortion with power saving, by increasing the dynamic range only when an output exceeding a clip voltage takes place.  
     CONSTITUTION: When an audio signal is applied to an input terminal IN, the input signal is amplified at an amplification section A1 and an output is obtained from a speaker SP. If the output exceeds a clip voltage Vcp, the output of comparators A2, A3 is inverted to "H", the output of OR gates A4, A5 go to "H", the output of an inverter 6 goes to "L", transistors (TR) Q5, Q6 turn off and TRsQ1∼Q4 turn on. Thus, capacitors C1, C2 are connected to a power supply line and they act like a voltage doubling circuit to the A1. Thus, the voltage Vcp rises at a period where the output of the A1 exceeds the reference value, the dynamic range is extended and a large output without  distortion can be achieved with saved power.
