The crimps are arranged to impede a moisture path from the tinsel lead to the voice coil lead. | 03-19-2009 |
20090274337 | SPEAKER VOICE COIL - The present invention is to provide a speaker voice coil having an improved productivity, a lightweight, a good response to vibration, and an elimination of a specified frequency. The speaker voice coil includes a plurality of coil main bodies connected in series each other, the coil main bodies each have a lead-in wire portion and a lead-out wire portion at a periphery of an end of the respective coil main bodies, the lead-in wire portion of one coil main body continuously communicating with the lead-out wire portion of the adjacent coil main body. | 11-05-2009 |
20100092024 | SPEAKER DEVICE - A drive cone | 04-15-2010 |
20100172536 | LOUDSPEAKER - A leader line of a voice coil from a conductive wire part is drawn out from a part between a diaphragm coupling part and a part disposed in the magnetic gap toward a frame in a non-contact state with a diaphragm. One end side of the second edge made of an elastic body is coupled to a part between a drawing part of the leader line on the voice coil and a part of the voice coil disposed in the magnetic gap. The other end side of the second edge is coupled to the frame. A suspension holder is integrated with the proximity of a coupling part of the second edge to the voice coil. The suspension holder is stuck to the voice coil using an adhesive. The disturbance of the movement of the voice coil can be reduced. | 07-08-2010 |
20100195863 | SPEAKER - A speaker having a drive cone and a diaphragm which can deal with higher output. The speaker comprises a frame, a magnetic circuit section, and a vibrating section. The magnetic circuit section is fixed to the frame. The vibrating section is housed in the frame and includes a drive cone ( | 08-05-2010 |
20100329503 | VOICE COIL AND TRANSDUCER HAVING THE VOICE COIL - A voice coil is disclosed. The voice coil includes a housing and a wire wrapped around the housing. The housing defines a connecting member and a combining member connected to the connecting member. The wire wraps around the combing member. The connecting member defines an outer surface, an inner surface opposed to the outer surface, and a top surface connecting the outer and inner surfaces. The housing further includes a through hole extending from the outer surface to the inner surface. | 12-30-2010 |
20110286623 | MOVING PART AND ELECTRODYNAMIC TRANSDUCER PROVIDED WITH SUCH A MOVING PART - The invention relates to a moving part for an electro-dynamic transducer, including at least one mandrel supporting a winding of at least one coiled wire. The mandrel includes at least one first element rigidly connected inside at least one second element for guiding the moving part inside the transducer. The first element has a winding support for the coiled wire so that the coil is located inside the mandrel, as well as vibration transmitter, such as a diaphragm, the vibration being generated by the movement of the coil induced by the flow of current in the coil wire. The invention also relates to an electro-dynamic transducer including such a moving part. | 11-24-2011 |
20120008817 | EARPHONE DRIVER AND METHOD OF MANUFACTURE - A balanced armature motor assembly has a circuit board mounted to a bobbin. A first end of a wire coil is secured to a first terminal on the circuit board and passes through a first cutout of the bobbin. A second end of the wire coil is secured to a second terminal on the circuit board and passes through a second cutout of the bobbin. The first end of the wire coil is oriented along a first line tangent to a center post of the bobbin, and the second end of the wire coil is oriented along a second line tangent to the center post of the bobbin. In another embodiment, a compressed polymer material is interposed between a first magnet and a post located on the bobbin and between a second magnet and the post on the bobbin. The polymer material forces the first and second magnets into contact with the pole piece such that the magnets can be welded to the pole piece. | 01-12-2012 |
20120257784 | SPEAKER VOICE COIL STRUCTURE - An improved speaker voice coil structure, the structure including: a bobbin; a first voice coil, wound around the bobbin and having a first terminal and a second terminal; a second voice coil, wound around the first voice coil and having a third terminal and a fourth terminal; and a third voice coil, wound around the second voice coil and having a fifth terminal and a sixth terminal. The improved voice coil structure thereby provides multiple optional connection terminals—from different layers with different values of impedance—for an input signal. | 10-11-2012 |
20130279736 | WIRE ROUTING FOR AN EARPIECE SPEAKER VOICE COIL - A wire routing for an earpiece speaker | 10-24-2013 |
20130315434 | MULTI-COIL UNIT, VOICE COIL, AND ELECTRO-ACOUSTIC TRANSDUCER USING THE SAME - The invention provides a multi-coil unit including first, second, . . . , (n− | 11-28-2013 |
20160381446 | AUDIO SPEAKER WITH A VOICE COIL ASSEMBLY AND A METHOD OF MANUFACTURING THE SPEAKER - A speaker includes a frame, a magnetic circuit and a deflectable diaphragm. The frame supports the magnetic circuit and the deflectable diaphragm. The magnetic circuit includes a yoke, permanent magnet, top plate and a voice coil former. The voice coil former includes a voice coil wrapped around a lower portion of the perimeter. In an embodiment, an inner wall of T-Yoke forms a through hole along the height of the T-Yoke. A lead wire fixture is positioned at least partially within the through hole. The lead wire fixture includes a cable that is spliced or stripped into one or more lead wires that electrically couples with the voice coil. In an embodiment, the cable, the lead wire fixture, and the lead wires are pre-assembled or integrated into a component. This integration helps to reduce the height and width of the speaker and helps to create a more compact speaker. | 12-29-2016 |
