  • Patent number: 9681225
    Abstract: Modulation systems and methods for use in parametric loudspeaker systems that can dynamically adjust modulation depths of ultrasonic carrier signals based on the levels of audio signals that the parametric loudspeaker systems are called upon to reproduce. The modulation systems and methods employ a dynamic level control function for determining a modulation offset that allows, (1) for low audio signal levels, a reduction of the modulation offset to obtain a reduced ultrasonic signal level, (2) for high level audio signals, full or maximum modulation of the ultrasonic carrier signal at an increased ultrasonic signal level, and, (3) for intermediate audio signal levels, under-modulation of the ultrasonic carrier signal at an intermediate ultrasonic signal level.

  • Patent number: 8861752
    Abstract: Techniques described herein generally relate to generating an audio signal with a speaker. In some examples, a speaker device is described that includes a membrane and a shutter. The membrane can be configured to oscillate along a first directional path and at a first frequency effective to generate an ultrasonic acoustic signal. The shutter can be positioned about the membrane and configured to modulate the ultrasonic acoustic signal such that an audio signal can be generated.

  • Publication number: 20140270269
    Abstract: A loudspeaker device includes a rear frame member defining a receiving space, a magnetic assembly, and a sound producing assembly. The magnetic assembly includes a yoke, a magnet, a magnetically permeable plate that cooperates with the yoke to form an air gap, and a connecting tube that passes through and fastens together the yoke, the magnet and the magnetically permeable plate, that is heat conductive, and that defines an axially extending air passageway in fluid communication with the receiving space. The sound producing assembly includes a vibrating member that cooperates with the magnetically permeable plate to define a chamber in fluid communication with the air passageway and the air gap.

  • Patent number: 8831253
    Abstract: An electroacoustic apparatus with an optical energy conversion function is provided. The electroacoustic apparatus includes an optical energy converter for converting optical energy into electrical power. The electroacoustic apparatus further includes a signal generator and a flat speaker. The signal generator receives a signal from a sound source and generates a sound signal according to the received signal. The signal generator sends the sound signal to the flat speaker, and the flat speaker makes a sound according to the sound signal. Aforementioned operations are all performed by using the electrical power generated by the optical energy converter or a power stored therein.

  • Patent number: 8818006
    Abstract: A loudspeaker system includes an enclosure surrounding a plurality of loudspeakers. The plurality of loudspeakers are disposed in series along a straight line in the enclosure. The enclosure includes a front panel, a back panel and side panels. The front panel, the side panels, and the back panel are disposed parallel to the straight line on which the loudspeakers are arranged. The side panels are provided with a front slit and a back slit. The back slit is disposed at an opposite side of the front slit in the enclosure. Sounds emitted to the upper and lower sides of diaphragms of the loudspeakers are separated from each other such that the sounds are prevented from mixing with each other. This provides a loudspeaker system capable of achieving desired sound pressure-frequency characteristics.

  • Patent number: 8761417
    Abstract: Transducers and resonators are embedded in body support structures in contact with a user to for the purpose of conveying musical sound energy to a user's body at selected frequencies and in selected patterns. Body support structures comprise beds, pillows, chairs, and other structures typically used to support people. The sound may be audio tones and/or music. The transducers and resonators may be incorporated into a foam component or in a coil spring component of the body support structure. Latex-type foams and beds made with springs are candidate body support structures for receiving transducer's and resonators. Electro-active polymers are also used as transducers. Floor systems are activated by both mechanical transducers and electro-active polymers.
