  • Patent number: 10123111
    Abstract: A passive cardioid acoustical system, or loudspeaker, is described which is driven with a single electrical signal and provides a useful reduction of low-frequency sound intensity in the rearward direction while producing relatively high low-frequency sound intensity in the forward direction. This is accomplished by an acoustical circuit which modifies the magnitude and phase of sound radiated by the interior side of a vibrating diaphragm or diaphragms, and combines it with the sound radiated by the exterior side of the diaphragm or diaphragms, so as to cancel part of the rearward radiation and reinforce the forward radiation. The passive cardioid loudspeaker described employs an improved acoustical circuit which allows improved efficiency, as well as greater flexibility with regard to the size, maximum output, and effective frequency range of the loudspeaker, as compared to prior art.

The interior cavity may serve as a sealed back volume for the speaker during normal operation of the speaker. During normal operation, control circuitry in the interior cavity plays audio content through the speaker. When it is desired to cool the control circuitry and the speaker, the control circuitry supplies a subaudible signal to the speaker. Airflow regulators having one-way valves and valves that are controlled by the control circuitry are mounted in the housing. Movement of a diaphragm in the speaker when the subaudible speaker is applied causes the diaphragm to pump air through the airflow regulators, creating a cooling airflow through the interior cavity.

  • Patent number: 9641919
    Abstract: Voice-controlled devices that include one or more speakers for outputting audio. In some instances, the device includes at least one speaker within a cylindrical housing, with the speaker aimed or pointed away from a microphone coupled to the housing. For instance, if the microphone resides at or near the top of the cylindrical housing, then the speaker may point downwards along the longitudinal axis of the housing and away from the microphone. By pointing the speaker away from the microphone, the microphone will receive less sound from the speaker than if the speaker were pointed toward the microphone). Because the voice-controlled device may perform speech recognition on audio signals generated by the microphone, less sound from the speaker represented in the audio signal may result in more accurate speech recognition, and/or a lesser need to perform acoustic echo cancelation (AEC) on the generated audio signals.

  • Patent number: 8917875
    Abstract: A circuit for operating loudspeakers includes a first, second, third and fourth loudspeaker circuit, having one input each for injecting a signal and one output each for connecting a loudspeaker input. The loudspeaker circuits are designed to amplify the injected signal and to provide the amplified signal at the outputs thereof. The loudspeaker circuits can, for example, be used for a 2.1 sound system. The three channels for a 2.1 sound system can be implemented by an amplifier circuit with four loudspeaker circuits, one loudspeaker circuit each being required for the two stereo channels left and right. A subwoofer channel can be driven differentially by two loudspeaker circuits. The stereo channels are, by contrast, only still connected to one loudspeaker circuit each, and so the stereo channels require at least one further common ground cable.
