摘要： A method is provided for manufacturing a speaker diaphragm manufactured using a sheet material made of magnesium or magnesium alloy and including an annular cone portion along an outer peripheral edge of a dome portion. The method includes a dome preformation process of forming a dome preformation portion; a cone preformation process of forming an annular cone preformation portion; and a shaping process of shaping the dome preformation portion into the dome portion by pressing, shaping the cone preformation portion into the cone portion whose outer peripheral end at least extends to a substantially identical height position to a maximum protrusion position of the dome portion, and forming, along a boundary portion between the dome portion and the cone portion, an annular step portion to which a voice coil bobbin is attached.

摘要： A thin speaker driver has a supporting frame, a magnet assembly, a voice coil assembly, a spider, a surround, and a diaphragm. The diaphragm is curved in radial section and has multiple coaxially arranged arc portions. A radial section of each arc portion has a curvature radius. The curvature radiuses of the radial sections of the arc portions are different from each other. Two of the arc portions that are disposed adjacent to each other are tangent to each other at which the two adjacent arc portions connect to each other. With the curvature variation of the radial section of the arc portions, different arc portions can be use to create sounds with different pitches. Accordingly, the speaker driver can create sounds with wide frequency responses to achieve full-range operation and thickness of the speaker driver can be greatly reduced, such that the speaker driver can be thinned.

摘要： A loudspeaker includes a light-emitting element, a frame, a magnetic circuit provided with a magnetic gap, a diaphragm, a voice coil bobbin, and a voice coil. The diaphragm has an inner circumferential end including an end face facing the light-emitting element, and a light guide having a reflecting surface formed thereon and provided at a position where light enters from the end face. The first end of the voice coil bobbin is joined to the inner circumferential end of the diaphragm, and the second end is inserted into the magnetic gap. The voice coil is wound around the second end of the voice coil bobbin. Light from the light-emitting element enters the end face of the diaphragm, is diffused by the light guide, and is reflected on the reflecting surface.

摘要： A speaker that is designed to substantially eliminate wobble of the voice coil during operation, and thus remove that source of distortion and early failure of the speaker. This is accomplished with the creation of triangular ring that extends upward from the top edge of the voice coil bobbin with that ring mating with a flat diaphragm at a right angle directly above the top edge of the bobbin. The outer edge of the diaphragm connects to the inner edge of the surround at the point where a sloping side of the “triangle” is also connected and slopes down to the top edge of the bobbin where the opposite end is connected. The outer portion of the diaphragm provides the third side of the triangle.

摘要： The invention proposes a suspension mount for sound reproduction devices according to the flexural wave principle. Characteristic for such devices is that a panel 10 is provided which must be flexibly attached to a holder 17. The panel 10 is composed of a core layer with a perforated structure, and two cover layers 12 which cover the core layer 11. Since the usual edge borders of conventional loudspeakers must be designed very hard due to the size and weight of the panel 10, the quality of the sound reproduction by such a device is reduced. For that reason the objective of the invention is a suspension mount which avoids the drawbacks of the state of the art. To that end it is proposed to build the suspension mount with the core layer 11 and/or at least one of the cover layers 12. If the core layer 11 itself provides the flexible attachment, it is also possible without any great effort to flexibly attach the panel 10 away from the edge areas. In that case the flexibility of the perforated structure of the core layer 11 is used as a spring element.

摘要： A loudspeaker clamping structure embodying an improved compression driver is provided. The clamping structure is configured to utilize a totality of the air contained within a cover coupled to a magnet structure of a loudspeaker. The clamping structure includes a compression driver that extends about the periphery of a membrane for clamping the membrane to the magnet structure. The cover includes an annular ring configured to engage the compression driver. At least one of the ring and compression driver is configured with a plurality of interstices along its length to provide interstitial gaps when the ring and compression driver are engaged. The interstitial gaps allow a volume of air within a central cavity to communicate with a second volume of air located in a peripheral cavity, to increase the quantity of available air that the membrane radiates into, so that the dimensions of the cover can be reduced without diminishing the quality of sound, and particularly the low frequency response, produced by the loudspeaker.
