Abstract
Disclosed herein is a combined receiver and speaker. The combined receiver and speaker has a diaphragm, a voice coil, and a chip resistor. The diaphragm generates sounds of a predetermined frequency through vibrations caused by a sound pressure in speaker and receiver modes. The voice coil vibrates the diaphragm using a magnetic field formed around a magnet attached to the diaphragm and generated by applied voice current. The chip resistor decreases the intensity of the applied voice current. The voice current is selectively applied to the voice coil such that the voice current is applied to the voice coil from speaker terminals in speaker mode, while the voice current is applied to the voice coil via the chip resistor from receiver terminals in receiver mode.
Claims4
A combined receiver and speaker, comprising:
- a diaphragm for generating sounds of a predetermined frequency through vibrations caused by a sound pressure in speaker and receiver modes;
- a voice coil for vibrating the diaphragm using a magnetic field formed around a magnet attached to the diaphragm and generated by applied voice current;
- and
- a chip resistor for decreasing the intensity of the applied voice current;
- wherein the voice current is selectively applied to the voice coil such that the voice current is applied to the voice coil from speaker terminals in speaker mode, while the voice current is applied to the voice coil via the chip resistor from receiver terminals in receiver mode.
