  • Patent number: 9924263
    Abstract: A narrow-profile balanced subwoofer or similar speaker includes a number of drivers placed side by side in the same lateral plane, with a first set of drivers facing one direction and second set of drivers facing the opposite direction. Their orientation is such that the sum of the forces from the first set of drivers is equal and opposite the sum of the forces from the second set of drivers, thus cancelling, and the sum of the moments from all of the drivers about a center or pivot point substantially equals zero. The speaker may include three or more drivers, symmetrically or asymmetrically spaced. The drivers may be of the same or different sizes, and the audio signal amplitudes may be adjusted to help balance the speaker. Each set of drivers may output sound into separate sound ducts, which may output sound from one or more apertures.

  • Patent number: 9888332
    Abstract: The invention concerns a mobile terminal with at least two transducers (LSm, LSs1, LSS2) used simultaneously as loudspeakers for stereophonic effect. According to the invention, one of said transducers is a main transducer (LSm) with a main working frequency band (Bm) corresponding to at least the phone frequency band, while the other transducer is a secondary transducer (LSs1; LSs2) with a secondary working frequency band (Bs1; Bs2) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs1; Bs2) being greater than the lowest frequencies of said main working frequency band.

  • Patent number: 9877112
    Abstract: An audio system includes an audio panel. The audio panel includes a first face plate, a second face plate, and a core that includes a plurality of structural members that extend between the first face plate and the second face plate. The plurality of structural members define a plurality of cavities in the core. The audio system also includes a first piezoelectric actuator mounted to at least one of the first face plate, the second face plate, and the core. The first piezoelectric actuator is configured to convert electrical signals into mechanical energy to cause the audio panel to generate sound.

  • Patent number: 9860647
    Abstract: A high sound quality piezoelectric speaker includes a moving coil speaker, a support frame, a vibration plate, and a piezoelectric ceramic plate. The support frame is arranged on the moving coil speaker and the vibration plate is positioned on the support frame. With the piezoelectric ceramic plate being positioned on the vibration plate, the moving coil speaker and the piezoelectric ceramic plate may collaboratively and better handle both high-frequency and low-frequency sounds, exhibiting relatively wide playback band and making sound quality better, to thereby reach the standard of high sound quality and provide users with improved enjoyment of sound perception.

  • Patent number: 9763008
    Abstract: A system and method for driving a loudspeaker array across directivities and frequencies to maintain timbre constancy in a listening area is described. In one embodiment, a frequency independent room constant describing the listening area is determined using the directivity index of a first beam pattern, the direct-to-reverberant ratio DR at the listener's location in the listening area, and an estimated reverberation time T60 for the listening area at a designated frequency. On the basis of this room constant, an offset may be generated for a second beam pattern. The offset describes the decibel difference between first and second beam patterns to achieve constant timbre and may be used to adjust the second beam pattern at multiple frequencies. Maintaining constant timbre improves audio quality regardless of the characteristics of the listening area and the beam patterns used to represent sound program content. Other embodiments are also described.

  • Patent number: 9736582
    Abstract: An audio amplifier and a warning sound amplifier are connected in parallel to each other, relative to a voice coil of a loudspeaker. A resistor having an impedance greater than an impedance of the voice coil is connected to the voice coil and is also connected to the warning sound amplifier. An audio signal from the warning sound amplifier is input to the voice coil via the resistor. Thus, since the warning sound amplifier is connected to the resistor having the impedance greater than the impedance of the voice coil of the loudspeaker, even in a case where only the audio amplifier is operated, a large current is prevented from flowing into the warning sound amplifier.

  • Patent number: 9729960
    Abstract: An acoustic layer is added to a keyboard-type device including: enclosing walls, optionally—one or more microphones, a signal processing device, at least one audio transducer, and an acoustic waveguide. The acoustic layer adjoins one or more internal areas of a keyboard-type device. The signal processing device receives an internal signal from an electronic device either through wires or wirelessly. The signal processing device provides a directive sound enhancement of the audio input signals based on room acoustics, such as reverberation, echo, noise, delay, frequency response, and/or speaker-positional information that is determined by the signal processing device. The audio transducer device generates an audible audio output in response to an audio signal output from the signal processing device. The acoustic waveguide receives the audible audio output and generates an enhanced bass audio output from the acoustic waveguide.

    Abstract: A modular loudspeaker includes a plurality of chambers and a plurality of vibration plates. Each vibration plate is fixed to two chambers, to cause the chambers to be secured to each other in a certain orientation by the vibration plates. A vibrator is attached to each vibration plate. A processor and a wireless communication unit are received in each chamber. The vibrator attached to each vibration plate is electrically connected to the processor, and the processor is configured to control the vibrator to vibrate when the loudspeaker receives a wireless audio signal via the wireless communication unit, thereby causing the vibration plate to vibrate and output sound.
