摘要： An apparatus comprising: two electro-acoustic transducers, each having a diaphragm characterized by an axis defining a movement of the diaphragm; a housing supporting the electro-acoustic transducers, and maintaining each of the axes in a predetermined orientation relative to each other and to a cavity, wherein each transducer is coplanar to a side wall of the cavity, the side walls being joined by an end wall opposite an opening from the cavity, wherein a vector sum of inertial forces generated by a movement of the diaphragms and acoustic forces exerted against the side and end walls of the cavity by pressure caused by movement of the diaphragms is substantially zero; wherein the housing includes: a front-side duct having a front-side end-wall, a front-side of the first diaphragm and a front-side of the second diaphragm directly coupled to the front-side duct; a first / second back-side duct having a first / second back-side end-wall, a back-side of the first / second diaphragm directly coupled to the first / second back-side duct; wherein a vector sum of an acoustic force on the front-side end-wall, an acoustic force on the first back-side end-wall, and an acoustic force on the second back-side end-wall is substantially zero.

摘要： A system that includes a direct digital speaker volume control device configured to be coupled to a direct digital speaker. The direct digital speaker include many pressure producing elements being adapted to generate a sound at a sound pressure level (SPL) and at a given frequency in response to an input signal, without using digital to analog converter. The direct digital speaker inherently exhibits a frequency response throughout its entire frequency range. The direct digital speaker volume control device includes a module for providing few filters each having a distinct cutoff frequency such that each filter exhibits no attenuation below its cutoff frequency and an attenuation response above the filter's cutoff frequency. And a selector for selecting one of the filters according to a selection criterion that depends on a desired volume and frequency of generated sound, and applying the filter to the input signal for generating a filtered signal that fed to the speaker.

摘要： A system and method for reducing baffle vibration includes balancing an inertial force generated by two or more moving diaphragms and balancing an acoustic pressure acting on a housing supporting the two or more moving diaphragms such that a net force acting on the baffle is substantially zero. The acoustic force acting on the housing may be balanced independently of the inertial force balance. In another configuration, the acoustic force acting on the housing may be balanced by a non-zero net inertial force.

摘要： A receiver or loudspeaker having a plurality of sound generators each having a housing and a sound output. An oblong channel being formed by a channel forming element and parts of the housings, where the sound outputs are positioned on one side of a middle of the channel and a sound outlet of the channel being positioned on the other side of the middle, so that the channel has a length adapted to acoustically alter the sound. The use of the housings for forming the channels provides a more compact structure.
