摘要： Methods and apparatus are provided for waveguide structures and speaker assemblies. In one embodiment, a waveguide may include an input aperture configured to receive a sound signal from a sound source, and a plurality of isolated sound paths having substantially equal path lengths. Each isolated sound path may be formed within a housing of the waveguide and formed with a curved path to reduce the depth of the waveguide. The waveguide may include a plurality of plugs, wherein each plug divides an output of one of the isolated sound paths into a plurality of output sound paths and defines a plurality of output apertures of the waveguide. Each output sound path is characterized by a reduced width relative to the output of the isolated sound path, the plurality of output apertures configured to output a combined sound signal based, at least in part, on the plurality of sound signals.

摘要： A method of limiting the power applied to a loudspeaker is disclosed, in which both the voltage and current applied to the loudspeaker are measured, and instantaneous power is directly calculated and used to control the level of the input signal that drives the amplifier powering the loudspeaker. When the power applied to the loudspeaker exceeds a prescribed threshold, the input level to the power amplifier is reduced until the measured power falls below the threshold. Also disclosed is a method for indirectly determining the voice coil temperature from the loudspeaker's voltage and current and reducing power to the loudspeaker when the temperature exceeds a prescribed threshold. The power level is actively controlled to prevent damage to the loudspeaker and to minimize audibly objectionable artifacts.

摘要： Methods and apparatus are disclosed to reduce the size, weight, and heat loss of power modules mountable in loudspeakers. Disclosed embodiments replace conventional linear technology with high frequency switching technology in both the power supply and amplifier. In these embodiments Class-D switching occurs at a low and fixed frequency, using standard components, with audio performance improvements through adaptation of internal error correction. By permitting 100% modulation, maximum output power is obtained, and a simple clip-detecting scheme is possible. A half-bridge and full-bridge with a single main supply reservoir is disclosed, obtaining useful allocation of output power while enabling the use of a simplified power supply. Power supply improvements include simplification and high efficiency, while meeting the particular system requirements of this scheme. Advantages include: increased acoustic output, reduced distortion, wider frequency range, smaller and lighter speaker housings, and lower cost.

摘要： In a power amplifier including a power output stage connectable to a load having a minimum rated impedance, there is disclosed means for driving the power output stage so as to prevent excess power dissipation thereby caused by loads having impedances lower than the minimum rated impedance. A capacitor is utilized to establish a desired voltage level for an amplification stage which provides the current for the power output stage, the maximum current being determined by the voltage level on the capacitor. Means are provided for charging the capacitor to the desired voltage level, the charging means being incapable of maintaining the desired voltage level on the capacitor in the presence of currents from the amplification stage at or near the maximum desired output current. A portion of the output of the power output stage is fed back to the capacitor to maintain the charge thereon at the desired voltage level; however, this is only operative when the impedance of the load is equal to or greater than the rated minimum impedance so that in the event of lower impedances, the charge on the capacitor is not maintained, reducing the current limit from the amplification stage.

摘要： A loudspeaker system consisting of a plurality of direct-radiating electro-acoustical drivers arrayed along a spiral line. The acoustical drivers may be directly coupled to an acoustical waveguide without use of adapters or a throat section. The waveguide and the acoustical drivers may thus be oriented along the spiral line so as to produce controlled vertical and horizontal angular coverage with improved phase coherence and reduced distortion. A plurality of phase plugs may be interspersed between the plurality of acoustical drivers to assist in equalizing the sound path to achieve uniform phase at the mouth of the waveguide.
