Abstract: A sound emission control device comprises a plurality of guides. The guides each include an inlet connected to a branching portion that is configured to oppose a vibrating surface inside an acoustic device, an outlet communicated to the inlet, and a horn-shaped inner wall surrounding a space between the inlet and the outlet. The guides are configured to guide sound that is emitted from the vibrating surface and branched by the branching portion to the outlets that are configured to be communicated to sound emission holes that are provided in the acoustic device and face mutually different directions, respectively.

Abstract: A sound diffuser includes a first annular control member, a second annular control member, and a third annular control member. The first annular control member includes a first communication hole and an annular inclined plate that surrounds the first communication hole and is inclined relative to an axial direction of the first communication hole. The second annular control member includes a second communication hole and an annular inclined plate that surrounds the second communication hole, houses the first annular control member therein, and is inclined relative to an axial direction of the second communication hole. The third annular control member has a plurality of third communication holes and surrounds the second annular control member.

Abstract: Provided is a speaker device, including: a speaker unit; and a speaker cabinet to which the speaker unit is mounted. The speaker cabinet includes an outer plate; and a partition plate arranged between the outer plate and the speaker unit so as to be opposed to the outer plate. The outer plate and the partition plate form a bass reflex port communicating with a rear space of the speaker unit, and the partition plate includes a leading end surface inclined so as to gradually increase a distance from the outer plate as extending forward.

Abstract: Provided is a handle component to be mounted to an opening portion formed in a side plate of a cabinet, including: a flange portion configured to be brought into contact with a peripheral edge portion of the opening portion on an inner surface of the side plate; a bottom wall portion including a recessed surface; a handle, which has a bar-like shape and via which both side portions of the bottom wall portion are connected in a bridging manner; and a protruding portion, which is formed on at least one of both end portions of the bottom wall portion arranged at both ends in a direction orthogonal to a longitudinal direction of the handle, and is configured to cover an end face of the opening portion of the side plate, wherein the protruding portion includes a surface projecting outward to be continuous with the recessed surface.
