摘要： 本发明公开了一种音箱及系统，该音箱包括壳体和设置于壳体内的处理模块、1个双端子低音扬声器和2N个高音扬声器，本申请中，双端子低音扬声器具有两个输入端，具体为左声道输入端和右声道输入端，双端子低音扬声器通过左右声道输入端分别接收左声道低频音源信号和右声道低频音源信号。通过该种方式，便无需对输入至双端子低音扬声器的左右声道低频音源信号进行编码，从而保留了原左右声道低频音源信号的完整性，保证了音效；只用一个低音扬声器，但声音通道数量并未改变，降低了功耗且保证了音效；此外，双端子可以降低低音扬声器的低频共振频率，使和高音扬声器配合时两者的分频点可以设的较低，利于音箱的低频的重放，低频音效的展示更充分。

摘要： A method, computer program product, and computing system for encoding audio encounter information of a reference audio acquisition device of a plurality of audio acquisition devices of an audio recording system, thus defining encoded reference audio encounter information. Location information may be estimated, via a machine vision system, for an acoustic source within an acoustic environment. One or more acoustic relative transfer functions may be selected from a plurality of acoustic relative transfer functions for the plurality of audio acquisition devices of the audio recording system based upon, at least in part, the location information. The encoded reference audio encounter information and a representation of the selected one or more acoustic relative transfer function may be transmitted.

摘要： A direct hearing device includes an inner actuator element that interacts with a subject's tympanic membrane, the inner actuator element sitting in the subject's ear canal. The direct hearing device further includes an outer component that houses a microphone, circuitry that processes a signal from the microphone, and a battery. The outer component is configured to sit laterally in the subject's ear canal. Advantageously, the outer component is separable form the inner actuator element.

摘要： A processing system obtain signals that are generated by or generated based on sensors that are included in one or more hearing instruments. Additionally, the processing system determine, based on the signals, whether a posture of a user of the hearing instruments is a target posture. The processing system generate information based on the posture of the user.

摘要： An audio system and method of spatially rendering audio signals that uses modified virtual speaker panning is disclosed. The audio system may include a fixed number F of virtual speakers, and the modified virtual speaker panning may dynamically select and use a subset P of the fixed virtual speakers. The subset P of virtual speakers may be selected using a low energy speaker detection and culling method, a source geometry-based culling method, or both. One or more processing blocks in the decoder/virtualizer may be bypassed based on the energy level of the associated audio signal or the location of the sound source relative to the user/listener, respectively. In some embodiments, a virtual speaker that is designated as an active virtual speaker at a first time, may also be designated as an active virtual speaker at a second time to ensure the processing completes.

摘要： A system and method can determine a time-varying position of a sound in a multi-channel audio signal. At least one processor can: receive a multi-channel audio signal representing a sound, each channel of the multi-channel audio signal providing audio associated with a corresponding channel position around a perimeter of a soundstage; determine a time-varying volume level for each channel of the multi-channel audio signal; determine, from the time-varying volume levels and the channel positions, a time-varying position in the soundstage of the sound; and generate a location data signal representing the time-varying position of the sound. The channel positions can be time-invariant. The position magnitude can be scaled to provide a unit magnitude as a sound pans from a channel to an adjacent channel. The position azimuth angle can be scaled to account for center location bias.

摘要： Wireless communication schemes and techniques are described, wherein a secondary device is configured to eavesdrop information communicated between a source and a primary device. Secondary device transmits a NACK signal to jam ACK signals from the primary device to the audio source, forcing a retransmit of audio information from the source to the primary, and available over an eavesdropping link between the secondary device and the source.

摘要： Apparatus comprising a processor configured to: receive an audio signal from a close microphone (103), wherein the audio signal (105) is input in a spatial audio mixing, and the close microphone (103) is associated with a first sound source; receive a beam-formed audio signal (107) from a microphone array (101), wherein the beam-formed audio signal (107) is a result of forming a beam of the microphone array directed from the microphone array towards the close microphone so as to enhance the audio signal; determine a time duration where no further sound source is active within the sound scene comprising the first sound source; and determine a time difference (109), during the time duration, between the audio signal and the beam-formed audio signal to enable alignment of the audio signal and the beam-formed audio signal.
