Abstract

A speaker system that includes a printed circuit board (PCB) and a speaker assembly. The speaker assembly is embedded in the PCB. The speaker assembly may include a coil, a magnet, and a diaphragm. The coil is embedded in a material of the PCB. The magnet is located within the PCB and attached to the diaphragm. The coil is usable as a T-coil for hearing aid compatibility. The speaker system may be included in any device such as a mobile phone, a personal digital assistant (PDA), a computer, an electronic game device, an electronic audio device, or an electronic video device.

Claims
