However, for marketing reasons it is necessary to be able to present a serious of one type of devices, e.g. portable audio devices distinguishing over each other in the design. This causes increased manufacturing costs due to the need for individual molding tools for each individual cabinet.

  • Patent number: 7480389
    Abstract: This invention provides a sound source system capable of producing a desired coverage pattern with high SPL that may be steered towards a desired listening area. The sound source system may provide an array of sound sources where the coverage pattern and SPL may depend on the height, width, and depth of the assembled array. Adding height and width to the array may narrow the vertical and horizontal coverage patterns that are projected, respectively. To maintain a substantially constant coverage pattern, a frequency shading techniques may be used to keep the height of the array constant relative to the wavelength. Adding depth to the array may provide greater SPL with minimal effect on the coverage pattern because array's height and width have not changed. The sound source system may also coherently sum in the main lobe and provide substantial off-axis rejection. This may be done using an end-fired related principle where each sound source in the array may be delayed proportional to its delay distance.

    Abstract: In an arcuate array of speakers (100) the wind component of air motion near each speaker is converted into sound because the wind is trapped within the arc, and therefore the bass response is improved. The array acts like a single large speaker, of diameter equal to the array diameter, when radiating bass sounds. A central baffle (10) also directs the wind and contributes to converting wind into sound. A semi-circular arc can be used along with a symmetry baffle (500) that further directs the wind, so that the number of speakers required is reduced. The symmetry baffle can be the floor, on which rests a cabinet (1) embodying the arcuate array.

  • Patent number: 7343018
    Abstract: The invention relates to loudspeaker systems or loudspeaker columns as used in public address systems and at (pop) concerts. Such systems heretofore possess a frequency-dependent coverage angle and strong second and third order side lobes. The invention describes formulae of the voltage to be applied to the separate loudspeakers of the loudspeaker column, which makes it possible to realize the constant coverage angle over the entire frequency range and to suppress the side lobes to a far-reaching extent.

  • Patent number: 7329933
    Abstract: A microphone sensing element and a method for making the same are disclosed. The sensing element has a diaphragm and an attached electrical lead-out arm preferably made of polysilicon that are separated by an air gap from an underlying backplate region created on a conductive silicon substrate. The backplate region has acoustic holes created by removing an oxide filling in a continuous trench that surrounds hole edges and by removing oxide to form the air gap. The diaphragm is softly constrained along its edge by an elastic element that connects to a surrounding rigid polysilicon layer. The elastic element is typically a polymer such as parylene having a Young's modulus substantially less than that of the diaphragm. First and second electrodes are connected to the diaphragm through the lead-out arm and to the substrate through polysilicon via fillings, respectively, and thereby establish a variable capacitor circuit for acoustic sensing.

  • Patent number: 7319766
    Abstract: An improved in-wall speaker assembly providing better performance and less intrusion than prior art speakers. The speaker assembly is oriented such that the driver fires vertically, parallel to the wall studs, rather than horizontally and perpendicular to the wall studs. The cone and surround of the speaker assembly are generally rectangular and/or conform to the area available between studs. Additionally, the cone is not attached to the voice coil, but is connected to the voice coil by a shaft which transmits the energy from the voice coil to the cone. In another aspect of the invention, the cabinet or housing includes two housings.

  • Patent number: 7298860
    Abstract: The invention provides a system for enabling the assembly and suspension of a plurality of loudspeakers in a line array where the splay angle between the adjacent speakers can be adjusted and rigidly maintained. The line array system utilizes rigging frames that allow for the coupling and supporting of the loudspeakers through the use of adjustable hinge bars. The rigging frames and adjustable hinge bars together form and rigidly maintain the splay angles between adjacent loudspeakers and correspondingly the curvature of the line array speaker assembly.

  • Patent number: 7261180
    Abstract: A rigging system includes a lever arm permitting all speakers supported by the speaker whose rigging is adjusted to be angularly reoriented to focus the system, even out the coverage and fine tune the coverage. Multiple pivot attachment points for the moment arm are provided to enable an enhancement of the angular adjustment provided. A dozen or more angular positions can be provided for the lever arm to facilitate the trial-and-error method of optimizing the sound quality within the house.

  • Publication number: 20070160245
    Abstract: A personal voice-transmitted device includes at least one voice box and at least one voice-transmitted tube. The voice box has a speaker arranged therein, and is divided to a first space and a second space by the speaker. The voice-transmitted tube connects to one side of the voice box and extends outwardly and has an outlet. The device can generate and retain a low-pitched tone by resonance of the first space, and the low-pitched tone can be transmitted to the outside by the voice-transmitted tube to form an excellent low-pitched tone. The drawbacks of the prior art such as poor tone because of using an earphone, a shutting stress and an uncomfortable feeling because of inserting an earphone, an unsafe feeling because of hanging an earphone and a sanitation problem because of contacting an earphone can be improved. The device can be used with no restriction on occasions and time.

  • Patent number: 7225895
    Abstract: A speaker that is designed to substantially eliminate wobble of the voice coil during operation, and thus remove that source of distortion and early failure of the speaker. This is accomplished with the creation of triangular ring that extends upward from the top edge of the voice coil bobbin with that ring mating with a flat diaphragm at a right angle directly above the top edge of the bobbin. The outer edge of the diaphragm connects to the inner edge of the surround at the point where a sloping side of the “triangle” is also connected and slopes down to the top edge of the bobbin where the opposite end is connected. The outer portion of the diaphragm provides the third side of the triangle.

The housing extends from the track when the housing is released by the latching mechanism. A system for providing audio to a reservoir of water is also disclosed. The system comprises a reservoir shell capable of holding water and at least one speaker system according to the invention mounted to said reservoir shell above the water line. Each of the speaker systems is independently extendible from the shell.

  • Patent number: 7201251
    Abstract: A speaker cabinet design for providing adjustability of the number of speaker cabinets contained in a speaker array comprises female connectors (50) along the front and back edges on the top and right sides. A user of the cabinet can attach a mating second cabinet to any side of the first cabinet by inserting male connector (40) in the pass through assembly and securing to the female connector at all locations on that side. A user can connect a second speaker cabinet in a series or parallel electrical connection. This allows the user to build up to the desired number of speakers without purchasing a full speaker array. Furthermore, once the desired array is complete the user can remove only the number needed for transport. A variety of different speakers can be preloaded in the cabinet at the factory, thus giving the user flexibility in sound without having to remove and install different speakers.
