摘要： The present disclosure includes techniques for providing timing for outputting audio from two or more devices. An example method includes determining, at a first device, timing for outputting audio from a second device and a third device in an attempt to have the audio from the second and third devices play in a synchronized manner. The example method further includes communicating from the first device to the second device, using a first wireless communication technology (e.g., Wi-Fi), the timing for outputting the audio. The example method further includes communicating from the first device to the third device, using a second wireless communication technology (e.g., Bluetooth) that is different from the first wireless communication technology, the timing for outputting the audio.

摘要： A voice enabled device includes a transducer to capture multiple inaudible signals received from multiple ultrasonic speakers and audio recording electronics to process the multiple inaudible signals to generate digital output samples, which are recorded sound data comprising non-linearities from frequency-shifted versions of the multiple inaudible signals to within an audible frequency range. A processing device is to detect, within the recorded sound data, at least a portion of the non-linearities, e.g., via: comparison of the recorded sound data with expected patterns from an audible audio signal generated by human voice; and detection of non-linear variations within the recorded sound data as compared to the expected patterns. In response to the detection, the processing device is further to suppress an action programmed for response to a voice command corresponding to the recorded sound data.

摘要： A portable battery charger having a battery assembly, a security assembly, and a communication assembly is disclosed. The battery assembly includes a rechargeable battery that is stored within a rectangular housing. The security assembly includes various security features that are stored within the housing such as a pepper spray dispenser and a high definition camera. Furthermore, the security assembly includes a voice recorder that clearly records audio from a surrounding area. Additionally, the video and audio that is captured is stored within an SD memory card that is inserted into the housing. The communication assembly includes a wireless communication module within the housing that connects to a mobile device through a Bluetooth connection.

摘要： The present invention discloses an integrated karaoke device, which comprises a control unit, a main sound chamber and a microphone assembly connected to the main sound chamber. At least two symmetrically arranged speakers are provided within the main sound chamber. The microphone assembly comprises a microphone and a microphone holder. The microphone holder is made of a soft material. The microphone and the speakers are respectively electrically connected with the control unit. The present invention has the following advantageous effect: the symmetrical arrangement of the plurality of speakers within the sound chamber allows the sound vibrations generated by the plurality of speakers to cancel each other out, such that the vibrations are prevented from being transmitted to the microphone.

摘要： Systems and methods for power conservation on an audio bus through clock manipulation allow a clock signal on an audio bus such as a SOUNDWIRE audio bus to be stopped when there are no pending commands from a master device. The clock signal may resume when a new command from the master device is generated or the master device receives an interrupt from a slave device.
