An audio system with a loudspeaker configured to create an audio output, a sensor configured to detect at least the presence of at least one person at a position relative to the loudspeaker, and a processor configured to cause the loudspeaker to alter the audio output based on the position of the at least one person relative to the loudspeaker. Altering of the audio output includes adjusting at least one of a volume, a time delay, an equalization, or a radiation pattern of the audio output.

This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.

In a microphone authentication method, a sound emitting device sends authentication information to a sound collecting device. The sound collecting device receives the authentication information and sends a collected sound signal to the sound emitting device. The sound emitting device receives the collected sound signal sent from the sound collecting device that has received the authentication information within a partitioned space. The sound emitting device emits a sound based on the collected sound signal.

Embodiments are disclosed of a speaker capable of producing multi-frequency-range sound using bar magnets, multiple diaphragms, and a shared planar voice coil. The planar voice coil is located between the bar magnets and translates a received electric signal into the kinetic energy that vibrates the diaphragms, thus reproducing multi-frequency range sound. In some embodiments, the speaker generates bi-directional sound.

A speaker module is provided. The speaker module includes a housing, a speaker unit, and a modulating unit. The housing has a main segment and an extension segment connecting to the main segment and extending away from the main segment, the main segment and the extension segment communicate with each other and form a chamber. The speaker unit is disposed in the housing in a position that is relative to the main segment. The modulating unit is arranged to correspond to the extension segment and is positioned in the housing. The shape of a cross section of the modulating unit is compatible with the shape of a cross section of the extension segment, and a length between the speaker unit and the modulating unit along the chamber is greater than 0.

A suspension system is provided with a frame to mount to a side surface of a speaker cabinet with a plurality of apertures formed therethrough. The suspension system is also provided with a lever arm with a proximal end and a distal end that are both adapted to connect to an upper support. The lever arm also has an intermediate portion that is pivotally connected to the frame about a pivot axis with a plurality of arcuate slots formed through. Each arcuate slot is formed with an end stop that corresponds to a splay angle of the speaker cabinet relative to the upper support, and each slot aligns with one of the apertures to receive a pin. Whereby suspending the speaker cabinet from the upper support pivots the lever arm in a first direction until the pin engages the end stop.

An example method of operation may include identifying, in a particular room environment, a number of speakers and one or more microphones on a network controlled by a controller and amplifier, providing test signals to play sequentially from each amplifier channel of the amplifier and the speakers, monitoring the test signals from the one or more microphones simultaneously to detect operational speakers and amplifier channels, providing additional test signals to the speakers to determine tuning parameters, detecting the additional test signals at the one or more microphones controlled by the controller, and automatically establishing a background noise level and noise spectrum of the room environment based on the detected additional test signals.

An electronic device having several speaker modules that are acoustically in-phase and mechanically out-of-phase is disclosed. Embodiments include a pair of speaker modules mounted at respective ends of a lateral link, and the lateral link may be supported relative to a housing of the electronic device. The speaker modules may receive a same audio signal, and the audio signal may drive a first voicecoil in a first direction and a second voicecoil in a second direction. Accordingly, the speaker modules may be driven in mechanically different directions by the same audio signal, such that reactive forces cancel and/or mechanical energy is dissipate in the lateral link between the speaker modules. Other embodiments are also described and claimed.

An audio notification system for an autonomous vehicle (AV) determines that the AV is within range of a user and emits a sound though a speaker of the AV to notify that the user that the vehicle has arrived. The audio notification system may include a sensor for sensing that the user has accessed the AV, and turns off the sound in response to the user accessing the AV. The audio notification may be generated according to one or more audio options, e.g., volume, pitch, or audio pattern.

There is provided a computer-implemented method of generating audio signals for an array of loudspeakers, the method comprising: receiving a plurality of input audio signals, wherein a respective one of the plurality of input audio signals is to be reproduced, by the array, at each of a plurality of control points in an acoustic environment, and wherein each of the plurality of control points is associated with a respective one of a plurality of loudspeaker groups; receiving an estimate of a position of each of the plurality of control points; assigning, using the received estimate of the position of each of the plurality of control points, each of the loudspeakers in the array to at least one of the plurality of loudspeaker groups, wherein the assigning of a particular loudspeaker to a particular loudspeaker group is based on a relative position of the particular loudspeaker with respect to one or more of the at least one control points associated with the particular loudspeaker group; and generating a respective output audio signal for each of the loudspeakers in the array by applying a set of filters to the plurality of input audio signals, the output audio signal for a particular loudspeaker being generated according to the at least one loudspeaker group to which the particular loudspeaker is assigned.
