Abstract: A flexible arm that is configured to be located between and physically and electrically connect an acoustic module of an open-ear headphone to a battery housing of the open-ear headphone. The flexible arm defines an original resting length and position between the acoustic module and the battery housing. The flexible arm includes a flexible printed circuit that extends through the entire original resting length of the flexible arm and comprises a conductor that is configured to carry electrical energy between the acoustic module and the battery housing, and a flexible material that encases at least some of the flexible printed circuit. The length of the flexible printed circuit within the flexible arm is greater than the original resting length of the flexible arm. The flexible printed circuit can thus better accommodate tension or compression on the flexible arm as the flexible arm is bent from its original resting position.

Abstract: Microphone capsules for condenser or electret microphones often exhibit individual deviations from a desired ideal behavior, e.g. the frequency response and phase response. Particularly if a plurality of microphone capsules are interconnected to form a microphone array, suitable microphone capsules must be found in a selection process. Some of these deviations can be corrected electronically, e.g. by filtering with a corresponding filter that is individually adapted. An improved microphone capsule, with which an automatic selection and automatic assembly of circuit boards with microphone capsules is facilitated, comprises an electrostatic sound transducer, an amplifier element that outputs an amplified output signal of the electrostatic sound transducer, and at least one electronic memory element. Data obtained by a measurement and relating to the individual frequency response or phase response of the respective microphone capsule can be stored therein.
