Patent number: 7620189Abstract: A microphone includes a microphone capsule biased with a polarization voltage from a winding on a transformer. The polarization voltage is controlled by a regulation circuit that may have an analog regulation circuit and a digital regulation circuit. A controller adjusts the polarization voltage that varies the sensitivity of the microphone.Type: GrantFiled: March 30, 2005Date of Patent: November 17, 2009Assignee: AKG Acoustics GmbHInventors: Werner Lang, Kurt Nell

Publication number: 20090262956Abstract: A microphone and a method for producing a microphone with a sensitivity stipulated within narrow limits. The microphone each has a microphone capsule and an amplifier. A network of passive components, preferably resistors, is allocated to the amplifier. The sensitivity of the microphone is measured and the passive components are then disconnected to change the amplification of amplifier in the desired manner.Type: ApplicationFiled: April 20, 2009Publication date: October 22, 2009Applicant: AKG Acoustics GmbHInventor: Thomas Solderits

Patent number: 7439706Abstract: This system provides a method for determining whether ordinary battery cells, a battery pack, and/or a charger unit are attached to a portable electronic device. The system provides a center contact in a battery shaft that contacts a battery pack or a point on an individual battery and allows the device regulation unit to measure the voltage at that point. If the voltage is below a particular threshold, then the system determines that a battery pack may be inserted in the battery shaft and the portable electronic unit enters a battery pack mode. If the voltage is above the threshold voltage, then the portable electronic device enters the battery operation mode. If a voltage transition is sensed on the DEVICE START line, the portable electronic device determines that the charger is installed and the portable electronic device enters the appropriate mode.Type: GrantFiled: October 7, 2004Date of Patent: October 21, 2008Assignee: AKG Acoustics GmbHInventor: Erich Brenner

Patent number: 7400914Abstract: Wireless headphones operated by a storage battery and having a connector socket for the insertion of a charge plug of an electric connection into a power pack. The headphones further have at least one miniature loudspeaker, audio electronics, a reception part, and charging electronics to monitor the charging process of the storage battery. In order to be able to use the headphones even with a dead storage battery, a socket is provided for the insertion of a signal plug of an electrical connection with an audio device for the transmission of signals. The audio electronics conduct only the signals received via the signal plug to the loudspeakers when the signal plug is inserted.Type: GrantFiled: September 17, 2003Date of Patent: July 15, 2008Assignee: AKG Acoustics GmbHInventor: Christoph Schwald

Patent number: 7295628Abstract: A stereo multiplex encoder (MPX) for FM transmission with a digital signal processor utilizes residual sideband modulation in stereo transmission instead of the conventional double sideband modulation. The adjustment of the sampling frequency to the modulation frequency (fmod=fs/2) is carried out, so that the antialiasing filter of the DAC can be used which produces the residual sideband modulated signal.Type: GrantFiled: August 23, 2002Date of Patent: November 13, 2007Assignee: AKG Acoustics GmbHInventors: Hannes Breitschädel, Peter Schlager

Patent number: 7289638Abstract: An electroacoustic capsule or electroacoustic transducer for an electroacoustic device has electrostrictive or magnetostrictive elements connected to a controllable power supply. Dimensional changes of the electrostrictive or magnetostrictive elements cause changes of the inner geometry of the electroacoustic capsule or electroacoustic transducer. This allows the adjustment of the capsule or transducer to the electroacoustic device in which it is mounted so that individual and dynamic adjustments are possible.Type: GrantFiled: February 8, 2002Date of Patent: October 30, 2007Assignee: AKG Acoustics GmbHInventors: Gino Pavlovic, Kurt Nell
