    摘要: An internal magnetic circuit is formed by a plate forming a pole piece, a vertically magnetized magnet attached to a bottom face of the plate, and a yoke attached to a bottom face of the magnet. A magnetic gap is formed between the plate and the yoke. The yoke includes a bottom part attached to the bottom face of the magnet, a side part standing on the side of the plate, and a folded-back part folding downwards over the side part to face the magnetic gap. Thus, the internal magnetic circuit having a uniform magnetic flux density inside the magnetic gap along the direction of its length is provided.

    摘要: A duct is provided in a cabinet for radiating sound pressure emitted from a speaker unit. The duct comprises a first duct and a second duct. The first duct extends in a direction perpendicular to a radiating direction of the sound pressure radiated from a front side of the speaker unit. The second duct is connected to an end of the first duct. An inner end of of the second duct is communicated with the cabinet. The speaker unit is disposed at a connection of the first and second ducts.

    摘要: A dynamic loudspeaker unit having a voice coil formed with two windings in which a capacitor is connected in series to a parallel circuit, one circuit arm being composed of a series circuit of one of the two windings and an inductor and the other circuit arm being composed of the remaining winding. The dynamic loudspeaker unit thus constructed is housed in a bass-reflex type cabinet, whereby a shoulder characteristic having a large Q in a bass zone can be obtained, and due to a combination of the inductor and the capacitor, a desired lowest resonance frequency lower than an actual lowest resonance frequency can be selected. Thus, the reproducible bass range can be extended.
