Abstract: A loudspeaker configuration capable of generating stereophonic sound separation from relatively loudspeaker drivers that are not necessarily widely separated. For example, such a loudspeaker configuration can be used to generate relatively good sound separation from a single chassis, such as a single speaker box, a boom box, a clock radio or the like. This can advantageously save space in many environments. One embodiment uses four mid-tweeter speaker drivers and a bass driver. The four mid-tweeter speaker drivers are arranged facing outward approximately 90 degrees apart from each other. A speaker driver facing the listener reproduces a mid channel signal, for example, L+R. A speaker driver facing away from the listener reproduces the same mid channel signal or a delayed version of the mid channel signal. A left facing speaker reproduces a side channel, for example, L?R. A right facing speaker reproduces a side channel, for example, R?L.

Abstract: An audio system utilizes a method for detecting and adjusting a sound field effect thereof. The audio system includes a first speaker and a second speaker. The first speaker is used to emit a first sound signal, and the second speaker is used to emit a second sound signal. The method for adjusting the sound field effect includes the steps of detecting a specific position and adjusting the first speaker or the second speaker based on the specific position to focus the first sound signal and the second sound signal on the specific position.

Abstract: The present invention is intended as a method for producing an electromagnetic transducer of variable reluctance type, where the transducer's seismic mass side and load side are mounted together in a first step while the inner and/or outer air gaps are supplied with shims in order to create balanced air gaps in an axial direction between the bobbin core's arms and the inner and outer yokes, whereupon in a second step the bobbin core is fixed through the side piece to an adapter already attached in a corresponding free moving end of a spring suspension, with compliant properties working in an axial direction and arranged between the seismic mass side and the load side in resting state in order to maintain balanced air gaps when finally, in a third step, the shims are removed and the air gaps are released.

Abstract: A method and system for surround sound beam-forming using the overlapping portion of driver frequency ranges provides a low cost alternative to present external surround array systems. The overlapping frequency range of a pair of speaker drivers, generally a low-frequency and a high-frequency driver, is supplied with a surround channel information in a controlled phase relationship such that the surround channel information is propagated in a directivity pattern substantially differing from that of main channel information supplied to the low and high frequency drivers. The main channel information is generally directed at a listening area, while the surround channel information is directed away from the listening area so that the surround channel information is heard as a diffuse reflected field. An electronic network provides for control of the surround channel phase relationship and combining of main and surround signals via either an active or passive circuit.

Abstract: A speaker apparatus can ensure a large size and area of a diaphragm so as to improve reproducing capability in a low sound range and increase an output sound pressure, and can constitute a plurality of vibrating points (signal control points). An input signal Vin having a plurality of independent channels is inputted, then the signal input Vin is processed in a sound signal processing portion by calculating and adding of an interference canceling signal between the signal control points, by calculating and adding of a sound interference signal for causing the interference between outputs from the signal control points in an arbitrary point, etc., so as to be inputted to transducers that are attached to a single diaphragm. The transducer transduces an electric signal into mechanical vibration. A plurality of the signal control points are generated on the single diaphragm, and each signal control point cause the single diaphragm to vibrate.

Abstract: A web hosted system and user interface in a client-server architecture permits audio designers to perform acoustic prediction calculations from a thin client computer. A client computer or other Internet connect device having a display screen is used by an audio professional to access via the Internet a host computer which performs acoustic prediction calculations and returns results of the calculations to the client. The results of the calculations are returned in the form of data visualizations, such as an area view showing visualizations of sound pressure levels within a defined space, an impulse view showing the time domain response at a defined location, and/or a frequency domain view showing the frequency response at a defined location. Calculations are performed based on user-defined inputs, such as speaker type and location, sent to the host computer from the client computer and based on retrieval of loudspeaker data from one or more databases accessible by the host computer.

Abstract: Surround-effect, providing no unnatural feeling to the listeners who sit next to each other under side-by-side basis through virtual sound sources, is realized. A surround left channel signal SL and a surround right channel signal SR are mixed with an adder 10 and are in monaural. A first monophonic signal and a second monophonic signal thus resulted are supplied to a virtual localization processor 12. A first virtual localization output of the processor 12 is supplied to a front left speaker SPL and a front right speaker SPR and a second virtual localization output thereof is supplied to a front center speaker SPC. In this way, virtual sound sources can be created at the right and the left to the listener 2. Similarly, virtual sound sources can also be created at the right and the left to the listener 3. Sound fields from the virtual surround sources are in reverse to the listener 2 and the listener 3.
