摘要： Disclosed are an apparatus and method of processing an audio signal to optimize audio for a room environment. One example method of operation may include recording the audio signal generated within a particular room environment and processing the audio signal to create an original frequency response based on the audio signal. The method may also include identifying a target sub-region of the frequency response which has a predetermined area percentage of a total area under a curve generated by the frequency response, determining whether the target sub-region is a narrow energy region, creating a filter to adjust the frequency response, and applying the filter to the audio signal.

摘要： A limited rotation electromechanical torsional oscillator for driving a mirror in an optical deflection system. A drive armature is mounted on a torsion bar at the opposite end from the torsion bar support. The ends of the armature lie in an air gap between two pole pieces. The magnet flux in the gap is caused to vary by means of a drive winding which results in armature rotation. Resonant frequency is varied by adjustment of the length of the torsion bar and the flux density. Q is varied by means of resistance in series with the drive winding.

摘要： An in-ear receiver can be used in a headset and/or hearing aid and includes a housing in which at least one ear canal section is configured to be inserted into an ear canal of a wearer when the in-ear receiver is used as intended. The housing defines at least one outer contour that is configured with at least in one section adapted to the ear canal of the wearer. The in-ear receiver includes a sound transducer arranged in the housing, and at least one resonant cavity, which is formed in the housing and is divided by the sound transducer into a front volume and a rear volume. The sound transducer is a MEMS sound transducer, and the front volume and/or the rear volume have/has an inner contour adapted to the ear canal.

摘要： A speaker comprises a support structure having a circumferentially extending rim, a vibration member configured to be displaced relative to the support structure during operation of the speaker, and a suspension member suspending the vibration member relative to the support structure. The suspension member includes a radially outer portion attached to the rim of the support structure, a radially inner platform portion attached to the vibration member, and a plurality of beams. Each beam of the plurality of beams may extend from the radially outer portion to the radially inner platform portion. The plurality of beams is configured such that a resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member scales linearly with a beam width of the beams of the plurality of beams.
