Title: Howler tone circuit
Inventor: TOKUDA MASAMI
IPC: H04M19/04
Filed: 1982-06-23
Abstract: PURPOSE:To output a sound which is loud enough to draw a user's attention by a howler tone by connecting an acoustic equipment to a talking circuit in parallel while a handset is lifted, and providing a means of stopping a speech signal from flowing into the acoustic equipment. CONSTITUTION:When a user lifts the handset, a ring-back tone sounder SD is connected to the talking circuit SP in parallel through a hook switch HS3, constant voltage diodes ZD2 and ZD3, and a capacitor C2. The breakdown voltages of the constant voltage diodes ZD2 and ZD3 are set higher than a speech signal voltage during normal service, so the speech signal is prevented from driving the sounder SD. When the telephone set enters a off-hook state, a howler signal with a high voltage than said breakdown voltages is sent from an exchange to between terminals L1 and L2 and then the sounder SD is driven by the howler signal through the capacitor C2 and constant voltage diodes ZD2 and ZD3 to output the howler sound which is loud enough.
