Abstract: A super tweeter includes a magnetic base, a voice coil, a frame annularly mounted to the magnetic base, a central supporting member mounted on a central portion of the magnetic base, a diaphragm, an annular inner supporting member, and an annular outer supporting member. The diaphragm is connected between an annular outer side of the annular inner supporting member and an annular inner side of the annular outer supporting member. An annular inner side of the annular inner supporting member is engaged with the central supporting member. An annular outer side of the annular outer supporting member is engaged with the frame. The annular inner supporting member and the annular outer supporting member cause the diaphragm to vibrate in a balanced manner, generating super high frequency range of sound waves.

Abstract: A speaker includes a T-shape iron, a ring magnet, a pole plate, a frame, a diaphragm, a coil core portion, a voice coil, a first annular corrugated plate, and at least one second annular corrugated plate. The second annular corrugated plate has is bonded to an inner side or an outer side of an outer section of the first annular corrugated plate and spaced from the coil core portion, thereby increasing a thickness and strength of an outer section of the first annular corrugated plate for bearing higher power such that the speaker generates clear sound and that an inner section of the first annular corrugated plate generates sufficient sound pressure when a power outputted by the speaker is low.

Abstract: A hi-fi tweeter mainly comprises a diaphragm, an inner supporting edge, a voice coil, and a phase sensitive rectifier. The diaphragm is integrated with a coil core portion, made of unitary material to avoid structurally connecting to different material, and the inner supporting edge mounting the diaphragm and the coil core portion to the phase sensitive rectifier. The voice coil is wound around the coil core portion and produces excellent ultrahigh sound wave in 1 KHz-100 KHz range.

Abstract: A loudspeaker assembly includes a base, a supporting plate, a casing, and a loudspeaker. The supporting plate is securely mounted to the base and includes a jointing member formed on a side thereof. The casing has a first end securely engaged with the supporting plate and a second end. The loudspeaker has a first end extending beyond a second end of the casing and a second end with a planar bottom side in a universal joint connection with the jointing member on the supporting plate. The loudspeaker has a section, which is slidable relative to an inner periphery of the casing to allow adjustment of an orientation of the loudspeaker relative to the supporting plate.
