  • Patent number: 11044540
    Abstract: A variable waveguide speaker controls, narrows, and directs the dispersion of the lower driver array to handle far-field listening areas. The widening mid-section of the speaker directs the sound from the mid-driver array to mid-field listening areas. The top of the speaker is the widest, allowing the top array drivers to cover their widest dispersion for near-field listening areas. This form-follows-function design results in a modern shape and elegant enclosure, as well as superior audio performance. A unique laminar flow grill system consisting of a multi-layer sandwich arrangement protects the speaker components from performance damage UV rays, dust, debris, water and ice.

  • Patent number: 10976486
    Abstract: Devices that include light assemblies for providing visual feedback to users that operate the electronic devices. In some instances, the devices comprise voice-controlled devices and, therefore, include one or more microphones for receiving audible commands from the users. After receiving a command, for instance, one such voice-controlled device may cause a corresponding light assembly of the device to illuminate in some predefined manner. This illumination may indicate to the user that device has received the command. In other instances, the devices may illuminate the lighting assembly for an array of other purposes. For instance, one such device may illuminate the corresponding light assembly when powering on or off, playing music, outputting information to a user (e.g., via a speaker or display), or the like.

The speaker(s) are oriented to output sound directionally toward the base end and opposite to the microphone(s) in the top end. The sound may then be redirected in a radial outward direction from the center axis at the base end so that the sound is output symmetric to, and equidistance from, the microphone(s).

  • Patent number: 9800961
    Abstract: A portable loudspeaker includes an electro-acoustic driver which creates sound waves when operated and a housing having a front side to which the driver is secured. The loudspeaker also includes a battery supported by the housing for providing electrical power to the driver and a cover having an upper portion and a lower portion, and secured to the housing which can be moved between (i) a closed position in which the upper and lower portions overlie the driver, and (ii) an open position in which the upper and lower portions do not overlie the driver and are substantially disposed beneath a supporting base of the housing. A controller controls operation of the loudspeaker. When the cover is moved to the closed position, the controller mutes the driver if the driver was outputting acoustic waves when the cover was moved to the closed position.

  • Patent number: 9774935
    Abstract: A speaker device for reproducing an audio signal includes a first speaker including a first diaphragm and a first magnetic circuit that drives the first diaphragm, where the first diaphragm reproduces an audio signal including a predetermined frequency range, a second speaker including a second diaphragm and a second magnetic circuit that drives the second diaphragm, where the second diaphragm reproduces an audio signal including a frequency range substantially the same as the predetermined frequency range, and at least one cabinet having the first speaker and the second speaker mounted therein so that radiation directions of sounds are opposite to each other. At least part of a space formed between the first speaker and the second speaker communicates with the outside of the cabinet. When the speaker device reproduces the audio signal, the first diaphragm and the second diaphragm vibrate in opposite directions.

  • Patent number: 9532143
    Abstract: A method of optimizing the low frequency audio response emanating from a pair of low frequency transducers housed within a cabinet. The low frequency transducers are electrically connected to a power amplifier and source of audio content. The resonant frequency (Fs) and amplitude (Q) are characterized as to the high-pass pole of the low frequency transducers as they are mounted within the cabinet. An equalizer is placed between the amplifier and source of audio content for canceling the complex pole of the low frequency transducers and for establishing a new complex pole at a cut off frequency below which the sound generated by the low frequency transducers will diminish.
