Abstract: A loudspeaker structure with a push-latch coupling design includes an enclosure unit, a speaker driver, a mesh cover, and a push latch device. The push latch device includes a female latch portion and a male latch portion. The male latch portion is fixed on the inner side, and adjacent to the periphery, of the mesh cover and has a latching head. The female latch portion is fixed on, and adjacent to a through hole in, the front-panel frame of the enclosure unit and includes a locking mechanism. Once the latching head is inserted in the female latch portion, the locking mechanism enters a locking state, in which the mesh cover is locked to the enclosure unit and covers the speaker driver. A gentle press on the mesh cover can change the locking state into a release state to enable automatic separation between the mesh cover and the enclosure unit.

Abstract: A directional loudspeaker box with directional acoustic transmission holes includes a hollow housing and a loudspeaker. The hollow housing is provided with a front opening at the front end and has a peripheral portion adjacent to the front opening and formed with a plurality of directional acoustic transmission holes. The loudspeaker is fixed in the hollow housing and generates sound that can propagate out of the hollow housing through the front opening and the directional acoustic transmission holes. The angle at which each directional acoustic transmission hole is formed with respect to the central axis of the loudspeaker is a function of the axial distance between the directional acoustic transmission hole and the loudspeaker, wherein the smaller the axial distance, the larger the angle, and the larger the axial distance, the smaller the angle. Thus, the directional loudspeaker box effectively deals with near- and far-field sound effects.

Abstract: The present invention is to provide a loudspeaker enclosure structure which includes a hollow housing being a barrel-shaped housing whose outer surface is concavely provided with a plurality of directional grooves each evenly arranged along the circumferential direction of the hollow housing and extending from the front end to rear end of the hollow housing, and a reflective cover having a front side fixed to a rear opening of the hollow housing and concavely provided with an annular reflective groove adjacent to the periphery of the reflective cover. The hollow housing has a receiving space therein which is in communication with each directional groove through the reflective groove. Therefore, the sound generated by a loudspeaker fixed in the receiving space will not only propagate out of the front end of the hollow housing, but also be transmitted to the space surrounding the hollow housing by way of the directional grooves.

Abstract: The present invention is to provide a light-permeable housing, which includes a metal layer evenly formed with a plurality of apertures and a bonding layer made from a mixture of a light-permeable bonding material and a solid material (such as mineral or glass powder) with a particle size smaller than the diameter of each aperture. The bonding layer is formed on the metal layer and bonds tightly thereto through the apertures to form the light-permeable housing, allow passage of light projected from a lamp inside the light-permeable housing, and thereby impart light-permeability to the light-permeable housing. Meanwhile, the portion of the metal layer that is not formed with the apertures provides a light-shielding effect that allows the overlying bonding layer to show the texture and saturated colors of the solid material, and make the light-permeable housing suitable for use in outdoor landscaping and capable of blending perfectly into natural scenery.

The bonding layer is formed by curing a composite material made of an even mixture of an adhesive and a fire-resistant material, wherein the fire-resistant material is in a form of powder or particles and makes up 45% to 65% by weight of the composite material. Once cured, the composite material forms the bonding layer and is embedded in the mesh holes and pores of the fiber layer.

Abstract: An audio radiation type reflective sound box structure comprises a hollow cone tube having a first end received in a box, a second end extended out of an opening of the box to form an inclined side wall, and at least one vent disposed adjacent to the first end. When a diaphragm of a speaker mounted on an inner side edge of the second end generates vibrations, compressed air in the hollow cone tube is pushed out of the opening through the vent, and then collides with the outer edge of the inclined side wall and is diffused toward a peripheral direction adjacent to a front side of the speaker along an extension direction of the inclined side wall. Thus, the sounds reflected by the box can be evenly transmitted to a peripheral environment adjacent to the front side of the speaker.

Abstract: The present invention is to provide a speaker cabinet comprising a hollow case in which a top and a bottom thereof both are wavily tapered from a pair of opposite edges of a front opening to a rear thereof. By utilizing the wavy, rearward taper design of the top and the bottom, a ratio of an area of the opening to an area of the rear is increased. Thus, air inside the case will be compressed rearward when a diaphragm of a woofer vibrates. Next, the compressed air will quickly flow toward the rear along the wavy, rearward taper inner surfaces of the top and the bottom. As a result, air dynamic at the rear is higher and stronger low-frequency resonance of the cabinet can be generated.

Abstract: The present invention relates a speaker having a diaphragm around the rim of a frame on the speaker for disposing a magnetic member at the center of the diaphragm along the direction of a resonant space enclosed by the diaphragm and the frame. When a winding in the center of the frame is excited, the resonant space generates varying magnetic lines and an attraction-repulsion effect is generated in the center of the winding or a reserved space at the position of the periphery to vertically slide the magnetic member and cause the diaphragm to vibrate and generate sound. The present invention can effectively reduce the space occupied by the components such as the seat, core, and magnetic member, and greatly reduce the thickness of the speaker.
