A portable loudspeaker having a sound generating unit configured to output a sound signal with a stand-alone frequency characteristic when the portable loudspeaker is used in a stand-alone operating mode and to output a sound signal with a connected frequency characteristic when the portable loudspeaker is used in a connected operating mode. The connected operating mode is defined when the portable loudspeaker is received by a docking module in a vehicle and is configured to enhance a bass output as compared to the stand-alone frequency characteristic.

Example techniques relate to changing a playback device mode based on a device base. In an example implementation, a first playback device operates in a first mode where it is connected to a first network and plays back audio content while in the first mode. The playback device detects connection of the first playback device to a device base and while the first playback device is on the device base, detects connection to a second network. The first playback device switches from operating in the first mode to operating in a second mode. The first playback device forms a stereo pair configuration with a second playback device over the second network in the second mode. While in the second mode, the first playback device plays back a first channel of audio content in synchrony with the second playback device playing back a second channel of the audio content.

The disclosure provides a personal media system including a base station and a wireless earbud. The personal media system interacts with a smartphone for wireless pairing. The base station has a connection hole to receive the wireless earbud. When the wireless earbud is plugged into the connection hole, the base station and wireless earbud form an integrated body.

A speaker apparatus, method, and system with a user selectably expandable chamber is provided. The chamber in its expanded state enhances the speaker's acoustical properties using a relatively stiff back plate of the speaker apparatus. The chamber in its collapsed state provides a thin profile for increased portability or low profile mounted solutions. The speaker is compatible with current electronics and may magnetically attach to a target surface such as a surface of a handheld device. The target surface may effectively supplement the stiffness of the back plate.

An electronic apparatus appropriately outputs low-frequency sound to high-frequency sound to enable acoustic reproduction with high sound quality is disclosed. A portable information apparatus includes a first speaker; and an expansion device includes a second speaker. The portable information apparatus includes a mode switching unit for selecting a single mode or a combined mode; and an acoustic adjustment unit for adjusting acoustic data output to the first speaker and/or the second speaker. During the single mode, the acoustic adjustment unit outputs the acoustic data to the first speaker. During the combined mode, the acoustic adjustment unit extracts high-frequency sound from the acoustic data and outputs the high-frequency sound to the first speaker, and extracts low-frequency sound from the acoustic data and outputs the low-frequency sound to the second speaker.

A headset capable of wireless charging is provided. The headset capable of wireless charging according to one embodiment of the present invention comprises: a pair of body units including a housing equipped with a speaker and a cushion unit; a connecting unit configured to connect the pair of body units; a battery module embedded in at least one of the body units and connecting unit to provide driving power; and a wireless power receiving antenna configured to receive wireless power transmitted from the outside to supply power for charging the battery module.

An entertainment system is provided, the system comprising a portable media device configured to simultaneously produce an audible output signal and a plurality of vibratory output signals, the audible output signal representing a multi-track recording comprising a plurality of individual recorded tracks, each vibratory output signal based on at least one individual recorded track; and a plurality of actuators positioned at various locations on a user's body, each actuator configured to receive a respective one of the vibratory signals and to vibrate based on the received signal. A method of mixing a multi-track vibratory recording is also provided, the method comprising utilizing an entertainment system to feel vibrations representing individual recorded tracks on different locations of a user's body; and for each actuator, selecting at least one of the tracks based on suitability for driving the actuator, and providing, to the actuator, a vibratory signal derived from the selected track.

Various arrangements for reducing auditory spatial aliasing for a user are detailed herein. A first delay filter may be set that delays output of a first same audio signal by a first duration to a speaker of a first set of multiple speakers of a device compared to a second speaker of the first set of multiple speakers. A second delay filter may also be set that delays output of a second same audio signal by a second duration to a speaker of a second set of multiple speakers of the device compared to a second speaker of the second set of multiple speakers. The first same audio signal can be output using the first set of multiple speakers and the second same audio signal can be output using the second set of multiple speakers.

An audio headset receives one or more audio signals carrying one or more audio channels and processes the audio channels to generate stereo signals for output to a left and a right speaker of the audio headset. The processing determines a number of the audio channels carried in the received audio signal(s), adjusts level(s) of the audio channels based on the determined number of audio channels and/or adjusts gain and/or phase of the audio channels to control a perceived location of a listener wearing the headset relative to a source of sounds carried in the stereo signals.
