摘要： The present disclosure provides a speaker, including a frame, a magnetic circuit system and a vibration system accommodated in the frame; the frame includes a main body defining an accommodating space and a mounting portion extending from the main body toward the vibrating diaphragm; the vibrating diaphragm is fixed at the mounting portion; the main body and the mounting portion are integrally formed through double-shot molding by using two kinds of plastics, where the main body is made of PPA, and the mounting portion is made of LCP. According to the speaker provided in the present disclosure, a glued surface between the vibrating diaphragm and the mounting portion has good flatness, which helps to improve waterproof performance and performance yield of the speaker, and firmness of gluing the magnetic circuit system with the main body is high, which helps to improve reliability of the product when the product falls.

摘要： A transducer including a driven element and a magnet assembly. The magnet assembly is coupled to the driven element and includes a first and a second magnet, and a ferrous member. Each of the magnets have a first and second magnetic pole. The first magnetic pole of the first magnet and the first magnetic pole of the second magnet being proximate to each other and facing each other thereby defining a first magnetic zone therebetween, the first magnetic poles being similar, and the second magnetic poles being similar. The ferrous member couples a substantial amount of the magnetic field emanating from the second magnetic poles and directing the substantial amount of the magnetic field to a gap between the ferrous member and the first magnetic zone.

摘要： The present invention relates to a loudspeaker which can be arranged to minimise its overall depth while also increasing the breakup frequency and reducing potential rocking vibrations. Accordingly, the present invention is directed to a loudspeaker, comprising a magnet structure, and a voice coil lying within a magnetic field established by the magnet structure and responsive to electrical signals to undergo excursions from a rest position along an axis of motion; a driven body, connected to the voice coil and moveable to project acoustic waves from a front of the loudspeaker; and a suspension for providing a restoring force to the driven body towards the rest position, the suspension extending from an attachment point on the driven body to an attachment point on a fixed portion of the loudspeaker; wherein the driven body comprises a diaphragm and a support structure extending rearwardly from a connection point with the voice coil to a connection point with the suspension located rearward of the frontal part of the magnet structure.

摘要： An electromagnetic voice coil actuator comprises a pot core magnet structure having a magnetic flux conductive core, a field coil within the pot core magnet structure for generating magnetic field through the magnetic flux conductive core and across an air gap, a voice coil disposed within the air gap. The voice coil and the field coil are each driven by an amplified signal derived from the audio input signal to create an actuation force, wherein the pot core magnet structure uses a soft magnet core.

摘要： A micro geophone having pole pieces do not extend out around the sides of the magnet, thereby allowing a reduced geophone diameter for a given magnet diameter. The pole pieces are adhesively bonded to the magnet using an adhesive, which may be made suitably electrically conductive by silver or nickel fillers or non-conductive by mica fillers such as borosilicate glass micro-spheres. Axial space is economized by eliminating traditional spider retaining rings. The spider springs are seated directly against the coil form and secured by adhesive fillets disposed on the outward-facing spring circumferences. The spider springs include circumferential notches to receive adhesive. A two-piece bimetallic coil form of aluminum and a heavier material, joined by adhesive, is provided. Headers are affixed to the housing within the seats by adhesive. A straight or rounded chamfer at each of the geophone ends allows the overall geophone dimensions to be maximized.

摘要： An electrodynamic acoustic transducer has a diaphragm and a frame with a pole piece carrying a bulbous waveguide tip which reduces or eliminates high frequency distortions caused by destructive interference within the transducer. The bulbous-tip structure clears the moving parts of the transducer and minimizes diffraction of sound energy, extending forward approximately to the plane defined by the outer periphery of the diaphragm when the diaphragm and voice coil are at rest. The bulbous-tip waveguide member extends radially outward above the central radiating area of the transducer diaphragm or cone so as to obscure the center portion of the diaphragm.

摘要： A first electronic device includes a first coil that is operative in at least two modes. In a first mode, the first coil may be utilized to moves a membrane to produce one or more sound waves, register movement of a membrane to detect one or more sound waves, or generates one or more haptic outputs. In the second mode, the first coil may be used to inductively transmit power to and/or inductively receive power from a second coil included in a second electronic device. In various cases, the second coil may be a dedicated inductive power transmission coil. In other cases, the second coil may be capable of multimode operation similar to the first coil.
