  • Patent number: 10812905
    Abstract: A device and a method for audio signal processing for a piezoelectric speaker for generating sound waves in the audible wavelength spectrum includes a signal input for a digital audio signal, a digital correction unit for correcting a nonlinearity of the speaker, a digital PWM generator that converts the signal corrected by the correction unit into a pulse-width modulated switch signal, a power stage controllable by the switch signal such that the speaker can be charged with a voltage for deflecting a membrane, and a closed-loop control circuit that feeds the voltage back as a feedback signal, which includes a first signal noise in the audible frequency range. The closed-loop control circuit of the device includes a noise shaping unit in that shifts a noise energy of the first signal noise outside of the audible frequency range.

  • Patent number: 10785580
    Abstract: A method adjusts parameters of a hearing system which has a hearing aid device and a communication device, which is separate from the hearing aid device. A component for acoustic coupling of the hearing aid device to the ear of a hearing-aid wearer is fitted to the hearing aid device. A camera of the communication device is used to capture at least one image of the component used for acoustic coupling. A product identity of the component is identified from the captured image and acoustic transfer characteristics are assigned to the previously identified component. The parameters of the hearing system are adjusted on the basis of these acoustic transfer characteristics.
