    摘要： A speaker (1, 1a, 1b, 1c) and an electronic device (90) having the speaker (1, 1a, 1b, 1c) are disclosed. The speaker (1, 1a, 1b, 1c) has a main body (10) and a cover (20, 20a). The main body (10) has a drive unit (12, 12a) and a tube (13). The tube (13) is situated at a side of the drive unit (12, 12a). The cover (20, 20a) is situated above the main body (10) for covering the tube (13) and part of the drive unit (12, 12a) such that the speaker (1, 1a, 1b, 1c) has a covered portion (121) and an uncovered portion (122). The sound produced by the covered portion (121) is output via the tube (131) along a first direction (D1). The sound produced by the uncovered portion (122) is output along a second direction (D2).

    摘要： A tubular body (20) having an air flow passage, wherein an area of a cross section, in a direction perpendicular to a tube axis, of a space enclosed with an inner wall of the tubular body increases toward an open end (28) thereof, wherein a curvature of the inner wall at an end portion (24) of the tubular body near the open end is repeatedly increased and decreased along a circumferential direction of the inner wall, and wherein, when the inner wall in a cross section of the end portion in the direction perpendicular to the tube axis is viewed from the tube axis, a convex portion at which the inner wall protrudes in a direction away from the tube axis and a concave portion at which the inner wall is recessed in a direction toward the tube axis are repeatedly formed along the circumferential direction.

    摘要： A loudspeaker enclosure (302) defined by one or more panels (302f) housing a drive unit (for example a bass unit). The drive unit comprises a coil (306), a diaphragm (304), and a magnet (308). The magnet (308) is decoupled (316) from the one or more panels (302f) of the loudspeaker enclosure (302). Sound is generated by the movement of the diaphragm (304) and complementary movement of the magnet (308), on application of an appropriate electrical signal to the coil (306). The moving diaphragm (304) acts against a first volume of air (310) within the enclosure (302), while the movement of a surface (302r) coupled (320) to the magnet (308), acts against a second air volume (312), different from the first volume (310). The surface (302r) coupled to the magnet (308) is decoupled (322) from the one or more panels (302f) of the loudspeaker enclosure (302).

    摘要： A bass reflex port (30B) having a tubular shape for air flows, wherein an angle of a first inner radial line with respect to a reference plane including a center axis of the bass reflex port differs from an angle of a second inner radial line with respect to the reference plane, the first line being orthogonal to the center axis and passing a first characteristic point on an inner circumference of the bass reflex port in a first transverse cross section perpendicular to the center axis, the second line being orthogonal to the center axis and passing a second characteristic point corresponding to the first characteristic point and located on the inner circumference in a second transverse cross section perpendicular to the center axis, the first transverse cross section and the second transverse cross section differing form each other in position in a direction of extension of the center axis.
