  • Patent number: 9743178
    Abstract: A waterproof speaker includes a frame having a flared front opening with a diaphragm mounted thereto; a magnetic element mounted to a rear end of the frame; a voice coil support located in a central gap of the magnetic element and connected to the diaphragm; a suspension; a central post located inside the voice coil support and associated with the magnetic element; a coaxial tweeter connected to the central post; a voice coil located around the voice coil support; and a water-proofing unit located between the voice coil support and the central post without changing the height of the speaker and the stroke of the voice coil. The diaphragm and the water-proofing unit together prevent external moisture from reaching the magnetic element, enabling increased stability of the voice coil and prolonged outdoor service life of the SPEAKER.

  • Patent number: 9628902
    Abstract: A passive radiator structure includes an integrally formed diaphragm structure and a surround suspension. The diaphragm structure includes a diaphragm, a frame, and a web-like spider having a plurality of suspension arms integrally extended to between the diaphragm and the frame. The surround suspension has a radially inner gluing edge adhered to a radially inner location of the diaphragm structure around the diaphragm, and a radially outer gluing edge adhered to a radially outer location of the diaphragm structure around the frame. The surround suspension and the web-like spider of the diaphragm structure form two suspension elements for stably supporting the diaphragm, enabling minimized irregular shaking and reduced weight of the diaphragm, as well as reduced sound distortion, increased compliance and upgraded efficiency of the passive radiator structure.

  • Publication number: 20160127832
    Abstract: A speaker diaphragm supporting structure includes a basket defining a flared front opening and an internal shoulder portion, and having annular magnet mounted to a rear side thereof; a voice coil located in the annular magnet; a diaphragm including a soft suspended flange for fixing to the flared front opening of the basket, a rigid vibrating membrane having a centered voice coil fixing hole for gluing to around the voice coil, a plurality of supporting legs integrally formed on a rear side thereof and a fixing ring portion glued to rear ends of the supporting legs; and a flexible suspension member having an outer circumferential edge set on the internal shoulder portion of the basket and an inner circumferential edge glued to the fixing ring portion, so that the suspension member is held to around an outer side of the annular magnet.

  • Patent number: 8731230
    Abstract: A loudspeaker includes an outer frame with an annular magnet partially exposed from a bottom thereof; a voice coil located inside the annular magnet; a diaphragm glued to between an expanded front opening of the outer frame and the voice coil; a flexible suspension ring having an outer edge fixed to a stepped section of the outer frame and a central opening edge clearance-fitted to a middle/front portion of the annular magnet; and an inner frame having a front portion fitted around the voice coil, a rear portion located on the central opening edge of the flexible suspension ring, and legs extended between the front and rear portions to locate in front of slots formed on the annular magnet. Therefore, the loudspeaker has reduced depth and volume, increased vibration amplitude and stability, and high quality sound output.

  • Patent number: 8520877
    Abstract: A resonant structure for loudspeaker includes a basket defining a front opening and having an annular magnet mounted therein; a voice coil suspended inside the magnet; a diaphragm connected at a suspended flange to the front opening of the basket; at least one flexible suspension member spaced behind the diaphragm for connecting to a rear opening of the basket; and an inner frame having a front end glued to a rear wall surface of the diaphragm, a central area to the voice coil and a rear wing member to the flexible suspension member. When the voice coil moves forward and backward on the inner frame, best possible harmonic resonance between the diaphragm and the flexible suspension members can be obtained. The loudspeaker is effectively reduced in height, and bass response is enhanced to ensure upgraded sound quality.
