    摘要: A microphone 12 joined by a support means 16 to a case 14 which communicates speech into light displayed through a transparent case top 10. The support mean is made of a sufficiently flexible material so it functions as a clasp repeatedly without fracturing. The support means 16 can be molded construction or pieces 20, 22, 32 joined with adhesive, pressure, heat, fasteners or other means. The case top 10 is made of a transparent material. In addition, the case may receive case tops via tabs 48 and tab holes 50, adhesive or fasteners such through holes 44 and onto supports 46.

    摘要: A microphone transducer is provided, the microphone transducer comprising a housing and a transducer assembly supported within the housing and defining an internal acoustic space. The transducer assembly includes a magnet assembly, a diaphragm disposed adjacent the magnet assembly and having a front surface and a rear surface, and a coil attached to the rear surface of the diaphragm and capable of moving relative to the magnet assembly in response to acoustic waves impinging on the front surface. The transducer assembly further includes a primary port establishing acoustic communication between the internal acoustic space and an external cavity at least partially within the housing, and a secondary port located at the front surface of the diaphragm.

    摘要: The present disclosure relates to a method for simultaneously operating a loudspeaker assembly in a loudspeaker function and in a microphone function. The loudspeaker assembly comprises a coil, which is movably mounted in the magnetic field of a magnet, and a diaphragm, which is mechanically coupled to the coil, wherein the magnet produces a magnetic flux density (B), the coil, has an effective length in the magnetic field, and the diaphragm has an area (A). In order to determine a first transfer function ZM, a first calibration state is set, in which an external sound pressure (p) on the diaphragm is equal to zero. In order to determine a second transfer function ZC, a second calibration state is set, in which movement of the diaphragm is suppressed. Subsequently, in normal operation the current (I) flowing through the coil and the voltage (U) dropping across the coil are measured and the external sound pressure (p) on the diaphragm is determined using the magnetic flux density (B), the effective length of the coil in the magnetic field of the magnet, the first transfer function, the second transfer function, the area (A) of the diaphragm, the current (I) measured by the measuring device in normal operation, and the voltage (U) measured by the measuring device in normal operation. The present disclosure further relates to a corresponding loudspeaker assembly.
