Abstract:
1. A super tweeter comprising: a magnetic base; a single 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 including an annular inner side and an annular outer side, the diaphragm made of a light and rigid material; an annular inner supporting member including an annular inner side and an annular outer side, the annular inner supporting member made of a resilient and soft material different from that of the diaphragm; and an annular outer supporting member including an annular inner side and an annular outer side, the annular outer supporting member made of a resilient and soft material different from that of the diaphragm; wherein the diaphragm is attached to the annular outer side of the annular inner supporting member and the annular inner side of the annular outer supporting member such that the combination of the single voice coil with the diaphragm is located between the annular inner supporting member and the annular outer supporting member, the annular inner side of the annular inner supporting member is engaged with the central supporting member, the annular outer side of the annular outer supporting member is engaged with the frame so that the single voice coil is spaced apart from the annular inner supporting member and the annular outer supporting member, the annular inner supporting member and the annular outer supporting member causing the diaphragm to vibrate in a balanced manner, generating super high frequency range of sound waves.
