Patent ID: 7035423

Claim:
A portable communication terminal for receiving an incoming communication, the terminal having a compact electromagnetic induction actuator for producing a vibration as well as an audible signal, comprising: a magnetic vibration system having a plate magnet, a yoke and a pole piece; a cylindrical housing enclosing an upper and a lower leaf-spring suspension which sandwich vibration system; an audible generator disposed on one end of the cylindrical housing, the audible generator having a voice coil, a diaphragm attached to the voice coil; a pair of input terminal disposed on the housing and connected to the voice coil and the magnetic vibration system for conveying an electrical signal having a frequency that produce a vibration in the magnetic vibration system or the audible sound generator, depending on the frequency of the electrical signal; and an individual amplifier connected to the each input terminal and the amplifier is normally set in operating state by application of a voltage, and a signal from the input terminal is fed to one of the amplifier for adjusting the output signal of the amplifier when the portable communication terminal is awaiting an incoming call.
