Systems of the present disclosure include an electronic device with a chassis and a speaker assembly. The speaker assembly can include a speaker support surrounding a speaker and coupled to the chassis via a spring element. The spring element can be monolithically formed with a main body of the speaker support and be configured to reduce transmission of vibrations from the speaker to the chassis. For example, the spring element can include an arm that extends within an opening of the main body to connect the main body to a fastener secured to the chassis. The spring element can be provided with features that facilitate wide distribution of loads and relative movement between the speaker assembly and the chassis.

A plate member of an acoustic equipment includes a flat plate that constitutes at least a part of the plate member that is used in the acoustic equipment. The flat plate includes a first drawn portion and a second drawn portion. The first drawn portion is recessed in a thickness direction of the flat plate with respect to a predetermined plane orthogonal to the thickness direction of the flat plate and has a rectangular outline when viewed in the thickness direction of the flat plate. The first drawn portion and the second drawn portion are arranged adjacent to each other so as to provide a predetermined gap therebetween. When a standing wave is formed on the flat plate, the first drawn portion and the second drawn portion are arranged so that the gap is located in a position of an antinode of the standing wave.

A method for producing a plastic-coated loudspeaker housing comprises the putting together of a loudspeaker housing from a plurality of housing wall elements. The put-together loudspeaker housing is placed in a mold. This is followed by a surface coating of the put-together loudspeaker housing by introducing a liquid, curable plastic into the mold.

This invention provides a speaker cabinet, and the aforementioned speaker cabinet includes a containment space within; multiple reinforcing rib connectors pass through the space between the two faces on the inside of the aforementioned containment space with the largest area; when these two faces start moving towards or away from each other, the reinforcing rib connectors provide resistance in the opposite direction of the movement; the aforementioned cabinet and reinforcing rib connectors are created in one piece via extrusion blow moulding. The invention provides a speaker cabinet, where the total capacity of the cabinet can remain unchanged during use, and the cabinet is very light-weight, and the inner walls of the cavity are also very thin. Completely fulfils sound quality and portability requirements.

An on-vehicle woofer system includes: a speaker unit including a magnetic circuit and a diaphragm connected to the magnetic circuit, and capable of generating sound waves by electrically driving the magnetic circuit to vibrate the diaphragm; a Helmholtz resonator to which a first surface of the diaphragm is oriented, the Helmholtz resonator being connected to the speaker unit; a sealed container to which a second surface of the diaphragm that is a back surface of the first surface is oriented, the sealed container providing a sealed space connected to the speaker unit; and a tube penetrating the Helmholtz resonator, the speaker unit, and the sealed container.

A speaker housing includes: a front wall to which a speaker unit is to be attached; at least one first wall; at least one second wall; and a plurality of ribs attached to the first wall, wherein an internal space is formed by the front wall, the first wall, and the second wall, a plurality of meshes that segment the first wall are defined, and shapes of the ribs are determined based on directions of a maximum principal stress generated in the meshes due to vibrations when the vibrations occur in a state where the ribs are not provided in the first wall.
