Abstract

Embodiments of interruption-sound devices for producing an interruption sound signal in a telecommunications transmission signal comprising a signal generator circuit and a processor circuit, in accordance with the present invention. The interruption sound signals are input into the appropriate location of the telecommunications device such that the interruptee perceives characteristic sounds such as those encountered when a mobile phone is about to drop a call. As a result, the interruptee will place blame for call disconnection on the mobile-phone technology and not on the interruptor. The interruption-sound device is suitable for incorporated into an external interruption module, a landline phone, and a mobile phone.

Claims (3)

1. An interruption-sound device for producing an interruption-sound signal in a telecommunications transmission signal, the apparatus comprising:

a signal generating circuit for producing an interruption-sound signal; and

a processing circuit for processing the interruption-sound signal in combination with a voice signal generated by a microphone to produce a transmission signal including the interruption-sound signal, wherein the signal generating circuit comprises a radio-frequency phase-locked-loop synthesizer adapted to produce sideband frequencies to degrade or distort reception of a desired channel by adding modulation components to create interruption sound and to cause the transmission signal to be dropped.
