Abstract: A broadband transducer controlled by magnetic field coupling, the transducer has signal volume control of a hi-fi set that is achieved by means of variable resistance originally achieved instead by means of a magnetic field coupler, wherein, the magnetic field coupler has a primary coil and a secondary coil with an adjustable gap therebetween, an adjusting rod is provided in the gap for adjustment and control; thereby, magnetic resistance is controlled for controlling volume of sounds; using of low voltage amplifying saves energy source and lowers cost of production, and makes an amplifier have an ideal acoustic effect able to give sweet sounds such as is done with a vacuum tube type hi-fi set and to give pushout power such as is done with a transistor type hi-fi set.

Abstract: An improved structure of speaker cabinet comprising a housing opened on one side thereof, and comprising a front panel, wherein, a plurality of intermediate speakers can be held firm and get increased connecting strength when the front panel is integrally connected with the housing to thereby offset the frontward and rearward thrusts of the speakers. Moreover, a plurality of hollow posts located at the positions in correspondence with those of the connecting areas of the speakers to the cabinet can be filled therein with vibration absorbing material in order to reduce vibration at the earliest time. Such a design not only can reduce volume and weight of the cabinet, but also can improve sound quality and provide a hidden port to improve beauty and waterproofing effect of the cabinet.

Abstract: Synchronous dustproof cover structure for sound membrane. The dustproof cover structure being made of a light and rigid material. Multiple reinforcing ribs are perpendicularly disposed on one face of the dustproof cover at equal intervals. Bottom ends of the multiple reinforcing ribs are connected with adjoining sections of the sound basin and the sound ring. The circumference of the dustproof body is connected on the sound basin, whereby the dustproof cover, the sound basin and the sound ring are connected into an integral body and the sound basin and the dustproof cover are synchronously vibrated with the sound ring to emit sound. The multiple reinforcing ribs are connected with the sound basin and the sound ring at multiple points so as to enhance the rigidity and strength of the sound basin. Therefore, the distortion of the sound basin at high volume can be reduced and a good quality of sound can be achieved.

Abstract: A multi-directional mounting bracket for adjustably mounting an article, such as an audio speaker or light fixture, to a surface includes a first mounting member (10) for attachment of the bracket to the surface. A spherical housing (14) is connected to the first mounting member (10), and a receiving socket (20) is selectively mountable to the spherical housing (14) by engagement of a fastener (22) to the spherical housing (14). The receiving socket (20) is connected to a second mounting member (18) for attachment to the article. The receiving socket (20) is selectively mountable along a spherical orbit of the spherical housing (14), and thus provides a greater range of adjustment and positioning of the article with respect to the surface to which it is attached.
