Abstract: A vibration plate having a reinforced structural element is provided. The vibration plate includes a vibration plate main body. The vibration main body has a first surface and a second surface opposite to each other. The reinforced structural element is located between the first surface and the second surface. A material of the vibration plate main body is different from a material of the reinforced structural element.

Abstract: A symmetric dual suspension speaker structure is herein disclosed, comprising a basin frame, a U-shaped iron, a magnet permeability ferrite ring, a corrugated rim, a diaphragm, a sound coil, a damper clamped between the magnet permeability ferrite ring and the U-shaped iron, as well as a magnet, wherein the peripheral edge around the upper surface of the diaphragm can be stretched in the vertical direction to form a barrel component, and the corrugated rim is used to bond and fix the top end of the barrel component while the damper is used to bond and fix the bottom end of the barrel component, such that the sound coil can bring the barrel component of the diaphragm to vertically vibrate thus improving the instability existing in the bonding of the conventional diaphragm and the coil framework.

Abstract: A surround acoustic box system comprises at least a first separable acoustic box, at least a separable second acoustic box and a host acoustic box body, wherein the first separable acoustic box and the second separable acoustic box respectively has a forward speaker unit and a left front speaker for providing forward channels, and the host acoustic box body is a horizontal bar-like acoustic box and further includes a console circuit module, a power supply circuit module, at least a first positioning sensor part, at least a second positioning sensor part, at least two front speakers and at least two top speakers, in which the first separable acoustic box and the second separable acoustic box can be attached to the host acoustic box body or otherwise detached from the host acoustic box body so as to achieve various surround channel effects through the controls of the console circuit module.

Abstract: A portable speaker charging structure comprises an outer case body and a speaker device, wherein the outer case body includes an accommodation space having a charging device and at least a separable inner case, and wherein the separable inner case is placed over the charging device and the speaker device is placed on the separable inner case. The charging device allows to electrically charge the speaker device such that a user needs only to carry the outer case body when travelling outdoors without having to take the speaker and the charging device thereby significantly saving space occupied by the goods the user carrying along. In addition, the portable speaker charging structure according to the present invention can be further applied as a mobile power source.
