An integration unit IU for tuning an OEM sound system augmented with aftermarket components, such as an amplifier or a subwoofer. The integration unit is contained in a small housing that can be installed inconspicuously in most vehicles without removing the original head unit. The unit may comprise a DSP-based active line output converter that is configured to automatically detect the frequency response and phase of the OEM head unit. The unit performs various algorithms to detect and analyze crossovers, EQ, time delay, and allpass filters and then matches left and right audio channels. The IU may allow for low bass correction detecting and defeating the factory high pass filter. Still further, the IU can correct the various filters to ensure a clean, uncolored audio signal for the augmented components.

Provided is a technique to generate a call environment that prevents call contents from being heard by a person other than a person speaking on the phone in a case where call voice is output from a speaker. Speakers installed in an automobile are denoted by SP.sub.1, ..., SP.sub.N, a first filter coefficient used to generate an input signal for a speaker SP.sub.n is denoted by F.sub.n (ω), and a second filter coefficient that is different from the first filter coefficient and is used to generate an input signal for the speaker SP.sub.n is denoted by .sup.~F.sub.n (ω). A call environment generation method includes: an acoustic signal generation step of generating, when detecting a start signal of a call, a call-time acoustic signal that is obtained by adjusting volume of an acoustic signal to be reproduced during the call, by using a predetermined volume value; a first local signal generation step of generating a sound signal S.sub.n as an input signal for the speaker SP.sub.n from a voice signal of the call by using the first filter coefficient F.sub.n (ω); and a second local signal generation step of generating an acoustic signal A.sub.n as an input signal for the speaker SP.sub.n from the call-time acoustic signal by using the second filter coefficient .sup.~F.sub.n (ω).

When a speaker device is within communication range of an electronic device, various rules are used to determine whether to connect to or route audio data to the speaker device. For example, the electronic device may prompt the user to choose whether to connect to a wireless speaker device. In situations in which the user rejects connecting to the wireless speaker device, subsequent attempts by the speaker device to connect to the electronic device are also rejected or ignored without further prompting the user, or the wireless speaker device may be connected to the electronic device but audio data not routed to the wireless speaker device. By way of another example, the electronic device may determine whether to route audio data to a wireless speaker device based on signal strength and link quality metrics for wireless communication between the electronic device and one or more wireless speaker devices.

A method for operating a bone conduction communication system can include establishing a communicable connection, operating a transducer in an input mode wherein the bone conduction transducers are configured to detect a vibration associated with a bone of the user; transmitting an audio signal over the communicable connection; and operating the transducers responsive to the audio signal.

A method of wireless communication locator station to be disposed at specific location includes: detecting rotation angle information of client-based portable device, carried or worn by user, according to specific wireless communication standard between wireless communication locator station and client-based portable device when client-based portable device is within signal range of wireless communication locator station; generating head pose direction estimation according to calculated rotation angle information; and when head pose direction estimation indicates that a user turns face towards wireless communication locator station, sending packet signal from wireless communication locator station to server-based portable device, successfully paired with and security-connected with client-based portable device, so that server-based portable device can transfer packet signal to client-based portable device after receiving packet signal.

An electronic device is provided. The electronic device includes a communication module, a first ultra-wideband (UWB) module, a second UWB module, and a processor operatively connected to the communication module, the first UWB module, and the second UWB module, wherein the processor is configured to determine a direction of a user's gaze, based on data acquired from the first UWB module and data acquired from the second UWB module, select at least one external electronic device positioned in the gaze direction, and send, through the communication module, a request to the selected external electronic device to output media.

Methods for the distributed reception of receivers without significantly increasing the performance requirements of the system. In particular, this object is achieved by a method which is able to strongly improve the quality of the individual samples and thus of the signal emitted by the network in a receiver network with low complexity, without requiring a central coordinator, by means of a continuous, receiver-internal, independent combination of the received data through separate antennas, or which is able to increase the spatial coverage per receiver while maintaining the same quality of wireless transmission rates per microphone, as well as realize every scenario lying in between these extremes.
