Microphone

A speaker mounting system wherein the speaker is mounted to a support surface indirectly by a compliant gasket with no rigid mechanical coupling between the speaker and the surface. Accordingly, mechanical transmission of vibrations from the speaker to the surface is greatly reduced. The gasket has a cross-section configured as a curved beam with one end secured to the support surface and the other end terminated by a thickened portion having an interior annular groove receiving the open end edge of the rigid outer basket of the speaker.

Speaker mounting system

A loudspeaker system which can be utilized with laptop PCs employs a loudspeaker enclosure having a unique shape which can easily be mounted to the back of a display of the laptop PC and also be easily removed for storing and/or transporting. Additionally, the enclosures of the loudspeaker system have been designed to allow the physical coupling of them together into a compact package so that they can be easily stored and/or transported, for example, in a briefcase for use during transit or at a remote location. This coupling of the loudspeaker enclosures is realized by employing a loudspeaker enclosure which is in the form of an 'L-shape'. Consequently, the loudspeaker enclosures can be placed upon each other and locked into place forming a relatively small compact package.

Directional microphone

Full directional pickup coverage is realized by employing a pickup arrangement which provides a plurality of audio polar directivity patterns, i.e., directional beams. These polar directivity patterns are formed in a unique embodiment of the invention by generating a plurality of frequency independent time-delayed versions of a corresponding plurality of spatially sampled signals and by combining each of the plurality of spatially sampled signals with one or more selected ones of the time delayed versions to generate at least a similar plurality of polar directivity patterns. More specifically, the spatially sampled signals are combined with the delayed versions in such a manner that a greater number of polar directivity patterns can be considered than the number of spatially sampled signals. In a specific embodiment, the spatially sampled signals are acoustic (audio) and a plurality of microphones arranged in a predetermined spatial configuration is employed to obtain them.
