MOVING COIL MINIATURE LOUDSPEAKER MODULE
First Claim
1. Moving coil miniature loudspeaker comprisinga static part with a frame defining a principal plane of the miniature loudspeaker and having peripheral walls defining a lateral perimeter, and with a magnetic circuit arranged within the perimeter of the frame and rigidly attached thereto, the magnetic circuit comprising a permanent magnet, an air gap, and pole pieces of magnetically conducting material, anda movable diaphragm assembly configured for excursion in an axial direction perpendicular to the principal plane, the diaphragm assembly comprising a diaphragm arranged parallel to the principal plane of the miniature loudspeaker, wherein the diaphragm along its periphery is resiliently attached to the peripheral walls of the frame, and a voice coil attached to a rear side of the diaphragm, wherein the voice coil extends into the air gap,the miniature loudspeaker further comprisinga driver module with a flexible carrier having a proximal portion arranged within the perimeter of the frame and a distal portion arranged outside the perimeter of the frame, the flexible carrier carrying an output amplifier, wherein the flexible carrier is provided with electrically conductive traces connecting an amplifier input with input contact pads placed on the distal portion, and wherein the flexible carrier is further provided with electrically conductive traces connecting an amplifier output with output contact pads placed at the proximal portion,wherein the output amplifier is arranged on the proximal portion of the flexible carrier within the perimeter of the frame, wherein the proximal portion of the flexible carrier is rigidly attached to the static part, and wherein the output contact pads are connected with the voice coil through flexible lead wires.

Abstract
A miniature loudspeaker may include a driver module with a flexible carrier having a proximal portion arranged within the perimeter of the frame and a distal portion arranged outside the perimeter of the frame, the flexible carrier carrying an output amplifier. The flexible carrier may be provided with electrically conductive traces connecting an amplifier input with input contact pads placed on the distal portion. The flexible carrier may be provided with electrically conductive traces connecting an amplifier output with output contact pads placed at the proximal portion. The output amplifier may be arranged on the proximal portion of the flexible carrier within the perimeter of the frame. The proximal portion of the flexible carrier may be rigidly attached to the static part. The output contact pads may be connected with the voice coil through flexible lead wires.
