Abstract: Provided in the present invention is a stereo sound box, including: a box body. Two sets of sound generating units are provided on a surface of the box body, correspondingly for a left sound channel and a right sound channel. Each set of sound generating units includes a low sound unit and at least one high sound unit. The low sound units of the two sets of sound generating units are arranged to mirror each other so as to neutralize the inertia of vibrations. The high sound units are arranged outside each low sound unit. In the described stereo sound box, high-fidelity low sound can be maintained even while the box body is kept light.

Abstract: 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.

Abstract: The present invention relates to a method for making an aperture web. The method includes the steps of: moving a micro-textured web through a first member having male elements and a second member having discontinuous female elements, wherein the male elements are arranged in a staggered pattern.

Abstract: The present invention relates to a method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web. The present invention also relates to a method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.

Abstract: This invention discloses a kind of speaker structure with a loading hole. A characteristic is that it includes an active cavity that has a cone hole and a loading hole; a loudspeaker is sealed and secured on the said cone hole; the said active cavity is connected to the outside air through the said loading hole; the cone of the said loudspeaker has one side which is connected to the free space; another characteristic of this invention is that it includes a driven cavity that is connected to the said active cavity through the said loading hole; the cross-sectional area of the said loading hole is smaller than the cross-sectional area of the air passage on its either side; further, it is not larger than ? the effective area of all the vibration units in the said active cavity; also, the volume of the said active cavity does not exceed half the total volume of the said active cavity and driven cavity. The loading hole constitutes a loading component which improves the transient response of the speaker body.

Abstract: The present invention discloses a speaker enclosure, in particularly a blown molded hollow pressure vessel. The present invention discloses a speaker enclosure, which is formed at once and sealed better. The thickness of the enclosure can be very thin and hence reduce the weight of the speaker. The present invention discloses a speaker enclosure, which can use many of the existing products to replace the traditional speaker enclosure. The present invention discloses a speaker enclosure, which its audible unit directly connects to the blow opening tightly. The present invention discloses a speaker enclosure, which its audible unit is provided with a seal. When the audible unit and speaker enclosure are assembled, the seal and enclosure opening thereby are completely tight assembled together.

Abstract: This invention provides a kind of acoustic structure that uses passive diaphragm unit, it includes speaker unit, passive diaphragm unit, radiant tube; said passive diaphragm unit is located at the back of the cone of said speaker unit; the speaker unit has radiant tube on the sides; the said radiant tube end which is exposed in the air is located at the periphery of the cone of said speaker unit. It has the same orientation as the speaker unit; the said passive diaphragm unit vibrates when it is driven by the said speaker unit, the sound waves produced by the vibration of the said passive diaphragm unit are emitted by the radiant tube and radiant opening, and share the similar vocal point of the said speaker unit. With this, the sound effect of the full range sound is almost identical to the sound point sources, it also reduces the phase difference between the sound effects produced by the cone of speaker unit and the passive diaphragm unit, further enhanced the sound positioning feature.

Abstract: This invention discloses a kind of modular speaker component. A characteristic is that it includes a fixed part. This fixed part has a thin-walled structure. An active loudspeaker unit and passive diaphragm units are installed on it. Another characteristic is that it includes a sealed connection part. This sealed connection part is fixed on the said fixed part and it has sealing material; the said sealed connection part aligns, connects and secures the said fixed part to the opening of a rigid container. This causes the said fixed part and the rigid container to jointly form an airtight resonant space. The fixed part integrates the active loudspeaker unit and passive diaphragm units on top and combines with the sealed connection part fixed on it to form overall a universal high sound quality module that is unaffected by the rigid container.
