"Sonic holography", as described in U.S. patent 4,218,585 was first incorporated in the Carver C4000 preamplifier. It enhances stereo imaging by introducing a delayed and equalized signal from the right channel at the left loudspeaker to cancel the signal from the right loudspeaker at the listener's left ear (and vice versa).
This frequency is known as the free-space resonance of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity. The back EMF generated by this movement is also at its maximum. The electrical impedance of the speaker varies with the ...
Carver Europe B.V. was a Dutch company that developed and manufactured three-wheeled electric enclosed man-wide vehicles. The company's core technology was the Dynamic Vehicle Control (DVC) system, which enables narrow vehicles to make banked turns, [dubious – discuss] aiding stability when turning at high speeds.
Speaker drivers are the primary means for sound reproduction. They are used among other places in audio applications such as loudspeakers, headphones, telephones, megaphones, instrument amplifiers, television and monitor speakers, public address systems, portable radios, toys, and in many electronics devices that are designed to emit sound.
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
Loudspeaker acoustics is a subfield of acoustical engineering concerned with the design of loudspeakers. [1] It focuses on the reproduction of sound and the parameters involved in doing so in actual equipment.
Loudspeaker time-alignment, usually simply referred to as "time-alignment" or "Time-Align", is a term applied in loudspeaker systems which use multiple drivers (like woofer, mid-range and tweeter) to cover a wide audio range. It involves delaying the sound emanating from one or more drivers (greater than 2-way) to correct the transient response ...
Distributed mode loudspeakers function differently from most others, which typically produce sound by inducing pistonic motion in the diaphragm. Exciters for distributed mode loudspeakers include, but are not limited to, moving coil and piezoelectric devices, and are placed to correspond to the natural resonant model of the panel.
