  • Patent number: 11134354
    Abstract: A method is used of detecting whether a device is being worn, when the device comprises a first transducer and a second transducer. It is determined when a signal detected by at least one of the first and second transducers represents speech. It is then determined when said speech contains speech of a first acoustic class and speech of a second acoustic class. A first correlation signal is generated, representing a correlation between signals generated by the first and second transducers during at least one period when said speech contains speech of the first acoustic class. A second correlation signal is generated, representing a correlation between signals generated by the first and second transducers during at least one period when said speech contains speech of the second acoustic class. It is then determined from the first correlation signal and the second correlation signal whether the device is being worn.

  • Patent number: 11070930
    Abstract: A personalized room related transfer function (RRTF) for sound bars and speakers within a specific room is generated without the need for photographs of the listener's head or microphones in a headphone apparatus. A smart device aids the listener in creating his own RRTF by enabling the listener to select a general RRTF model based on the specific sound bar setup (e.g., sound bar; sound bar+subwoofer; sound bar+rear speakers+height; etc.) from a set of general RRTFs downloaded locally or from the cloud. A test signal is played from a specific driver of the sound bar, and the listener identifies a location at which he would like the perceived sound to originate. If the driver location signal and desired location are not the same, the app adjusts parameters and replays the test signal until the driver signal and the desired location are the same.

  • Patent number: 10812892
    Abstract: A wearable device and a power saving method are proposed. The wearable device includes a sensor and a first processing unit. The sensor has a buffer. The first processing unit is coupled to the sensor. The first processing unit in a first hibernate mode is woken up after receiving a first signal, wherein the first processing unit includes an interrupting module. The interrupting module makes the first processing unit enter the first hibernate mode after commands, in response to the first signal, the sensor to start sensing so as to generate sense data, wherein the sensor wakes up the first processing unit from the first hibernate mode based on an amount of the sense data exceeding a threshold of the buffer, and the first processing unit enters the first hibernate mode after processing the sense data.

  • Patent number: 10756691
    Abstract: A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive audio signals. The audio processing circuitry is operable to process the audio signals to detect strength of a chat component of the audio signals and strength of a game component of the audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.

  • Patent number: 10721550
    Abstract: Some embodiments of the disclosure provide systems and methods of detecting headphone rotation to properly process user input to the headphones. The systems and methods described herein may be used, for example, to detect a gesture (e.g., a swipe) received as user input on a touch interface of the headphones, such as a touch interface integrated into an ear piece. The gesture may be made in a particular direction, such as down toward Earth. However, headphones may be worn in a plurality of configurations, such as upright with the headband around the top of the head, downward with the headband around the back of the neck, or anywhere in between. Thus, the systems and methods described herein may be used to determine the rotation of the headphones in order to properly ascertain the intended gesture and perform an intended result.
