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.

This applications relates to methods and apparatus for monitoring a socket (101), to detect a connection status of a mating plug (102), e.g. for monitoring an audio jack socket for connection of an audio jack plug. A monitor (115, 305) is configured to monitor a voltage (V.sub.M) at a monitoring node (114), which is coupled to a jack detect contact (112) of the socket and a voltage pull-up element (113). The voltage (V.sub.M) at the monitoring node (114) is monitored against a threshold (Vthv) and a threshold module (302) is configured to vary the threshold depending on an indication of signal activity (S.sub.ACT) of a signal path for a first socket contact (103) which will be electrically connected to the jack detect contact when a plug when inserted in the socket.

Systems and methods are disclosed in which a playback device transmits a first sound signal including a predetermined waveform. In one example, the playback device receives a second sound signal including at least one reflection of the first sound signal. The second sound signal is processed to determine a location of a person relative to the playback device, and a characteristic of audio reproduction by the playback device is selected, based on the determined location of the person.

An audio apparatus includes a network interface, a receiver, at least one storage, and at least one processor. The processor is configured to determine that the audio apparatus is in a state capable of communicating with the other audio apparatus via the network interface. The processor is also configured to receive audio data via the receiver transmitted from an external apparatus different from the other audio apparatus. The processor is also configured to output a sound based on the received audio data. The processor is also configured to transmit the sound emission control information stored in the at least one storage to the other audio apparatus. The sound emission control information includes one or more of a sound volume, and a frequency band.

A speaker system is provided with a docking station, a removable housing mounted to the docking station, and a transducer supported by the removable housing. The speaker system is also provided with a processor supported by the removable housing and programmed to separate an audio signal into channels and provide at least one channel to the transducer based a location of the removable housing relative to the docking station.

A furniture system including a base and transverse member, with an induction charger provided in the transverse member and/or base, hidden from view and feel, embedded, e.g., at least 10 mm below the charging surface. In an embodiment, the transverse member includes a frame having an upper panel and an induction charger elastically secured at least partially above the upper panel such that the induction charger is elastically pushed down toward or through the upper panel when a force is exerted downward onto the induction charger. The induction charger elastically yields downward or otherwise toward or into the furniture system in response to loads, such as loads from sitting on the induction charger, to prevent damage thereto. The induction charger can elastically yield as such and still be positioned close enough to the surface of the furniture system to effectively charge electronic devices placed thereon.

An audio apparatus includes: a receiver which receives audio data transmitted by a broadcast method from an external apparatus; a sound emitter which performs sound emission of the audio data received by the receiver; a generator which generates sound emission control information relating to sound emission of other apparatus which can receive the audio data; and a transmitter which transmits the sound emission control information generated by the generator to the other apparatus.

The disclosure herein provides a mobile system including a base station and a wireless earbud. The base station comprising a connection hole, a user input button, at least one processor, at least one memory, and circuitry. The wireless earbud is configured for plugging into the connection hole of the base station to form an integrated body with the base station. The system is capable of wirelessly pairing with a smartphone for the wireless earbud to receive audio data originated from the smartphone.

A connecting wireless speaker and system which includes a speaker housing, a driver, a controller, a power source, and at least one wireless transceiver. The at least one wireless transceiver is capable of being operably linked to a wireless audio transmitting device. The connecting wireless speaker has a male connection port and a female connection port. Each connection port is configured to mate to its opposite connection port making an operable electronic connection between itself and a second speaker having said opposite connection port. Both speakers can be wirelessly connected to the wireless audio transmitting device. The invention also includes methods of using the connecting speakers and systems.
