Abstract
A speaker includes a housing including a front housing provided in a conductive material; a driver including a diaphragm; a magnetic circuit including a permanent magnet; and an electric circuit including a voice coil to which current is applied based on an input electrical signal, and a first electric circuit configured to vibrate the driver based on the voice coil and a magnetic field formed by the magnetic circuit; wherein the diaphragm include a coating that is surface-coated with a conductive material so as to have a capacitance with the front housing.
Claims5
A speaker, comprising:
- a front housing including a conductive material, and disposed in front of the speaker;
- a driver including a diaphragm;
- a magnetic circuit including a permanent magnet;
- and
- an electric circuit including a voice coil to which current is applied based on an input electrical signal, and a first electric circuit configured to vibrate the driver based on the voice coil and a magnetic field formed by the magnetic circuit;
- wherein a surface of the diaphragm is coated with the conductive material so as to have a capacitance with the front housing,
- wherein the front housing is partitioned into at least two areas that are insulated from each other, and
- wherein the surface of the diaphragm is partitioned into at least two areas that are insulated from each other, so as to have a capacitance with each of the partitioned areas of the front housing.
