  • Patent number: 10993029
    Abstract: An audio system on a headset presents audio content via tissue conduction to an inner ear of a first ear of a user. The system monitors, via one or more sensors on the headset, data about the presented audio content. The one or more sensors including at least one sensor configured to capture data about the presented audio content at a second ear of the user. The system estimates array transfer functions (ATFs) associated with the data, and generates sound filters for the transducer array using the estimated ATFs. The system presents adjusted audio content based in part on the sound filters. The adjusted audio content has a damped region at the second ear such that the amplitude of the adjusted audio content at the first ear has a higher amplitude than at the second ear.

  • Patent number: 10963213
    Abstract: A playback synchronization method and device and a USB sound card are disclosed. In the technical solutions according to the present disclosure, the number of writes for writing data into the audio data buffer by the write pointer of the master device and the number of reads for reading data from the audio data buffer by the read pointer of the slave device are acquired, and it is determined whether the data transmission of the master and slave devices is synchronized or not by judging the magnitude relationship between the number of writes and the number of reads. If it is not synchronized, the position of the read pointer is adjusted so that the write pointer and the read pointer are synchronized again, i.e., the write data and the read data are synchronized again. Thus, the problem that the clocks of the master and slave devices are relatively independent and the data transmission is not synchronized due to the clock deviation is solved.

  • Patent number: 10950217
    Abstract: A head-mounted wearable device (HMWD) provides audio output using acoustic quadrupole units (AQU). The AQU produces an acoustic pattern having a first region and a second region. The first region has a first phase and the second region has a second phase that is opposite the first phase. A major axis extending through the regions is directed generally upwards from the ear canal of the user. The ear of the user is within the first region. The second region is directed upward. Bystanders are within an acoustically null region of the acoustic pattern. The acoustically null region is perpendicular to the major axis. Within the acoustically null region, the sound intensity is reduced due to destructive interference between the first phase and the second phase. As a result, the user wearing the HMWD is able hear audio output while audio amplitude perceived by the bystanders is significantly reduced.

    Abstract: An acoustic meta material (AMM) spiral device for passive amplification of sound is described. The AMM amplifier device employs at least one deep sub-wavelength spiral design with high refraction index, based on an exponential spiral shape. The AMM spiral amplifier is used to focus on low frequency sound amplification and to cover broadband frequency range. Sound emanating from a speaker travels into a spiral channel until reaching the apex of the spiral. When twin spirals are used, the sound then enters a second spiral for radiating into open air.
