Abstract: Provided is an acoustic reproduction device that includes a first acoustic reproduction unit, and a second acoustic reproduction unit, in which the first acoustic reproduction unit includes a housing having a cylindrical shape and a vibration exciter that vibrates an end surface of one end of the housing. The second acoustic reproduction unit includes a speaker unit and a diffuser that changes a radiation direction of sound reproduced by the speaker unit. The housing, the speaker unit, and the diffuser are arranged so as to be substantially coaxial with a predetermined axis, and the diffuser causes a radiation direction of sound reproduced by the speaker unit and a radiation direction of sound from the first acoustic reproduction unit to be substantially a same.

Abstract: 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.

Abstract: 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.

Abstract: 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.
