    摘要： In various embodiments, vibro-acoustic transducer arrangements in accordance herewith are optimized for sensing and transducing acoustic phenomena occurring within a patient's body, and manifesting themselves at the skin surface with frequencies ranging from 0.001 Hz to 10 kHz. Strategies for effectively coupling to the skin include judicious mismatching of mechanical impedance, the use of impedance-matching gels or liquids, a shaped (e.g., domed) pickup, material selection, and/or a peripheral leaf-spring arrangement permitting relative movement between inner and peripheral diaphragm portions. The spring stiffness or spring compliance of the leaf springs may be selectively chosen to optimize the frequency response of the sensor.

    摘要： A receiver is provided comprising an outside housing, and a magnetic circuit system and a vibration system accommodated in the outside housing. The vibration system comprises a vibration diaphragm and a voice coil. The outside housing comprises a first housing and a second housing matching with each other. The first housing and the second housing are provided with electrical connection structures conductive to one another thereon. The first housing is provided with a first elastic piece on a sidewall thereof. One end of the first elastic piece is welded with a spring electrically connected to an external circuit, and the other end is exposed at the outside of the sidewall of the first housing. The second housing is provided with a second elastic piece on a sidewall thereof. One end of the second elastic piece is electrically connected to a lead wire of the voice coil, and the other end of the second elastic piece is exposed at the outside of the sidewall of the second housing and is welded and fixed with the portion of the first elastic piece exposed at the outside. The receiver of the present utility model can reduce the lateral dimension of a product without impairing the performance of the product, and can satisfy the restrictive requirement on the lateral dimension of the product when assembled with a terminal electronic device.

    摘要： In a unidirectional dynamic microphone unit, a cylindrical tube is provided to cover the microphone unit, a cylindrical wall of a first cylindrical portion that is included in the cylindrical tube and extends to at least the rearward is provided with a rear sound wave introducing portion weighted such that an acoustic resistance value is gradually made smaller toward the rearward side from positions of sound holes for taking in a sound wave transmitting around from the rearward side, preferably formed of a trumpet-shaped opening, and it is possible to enhance the sensibility to sound pressures without degradation of the frequency response and the directionality.

    摘要： A tunable ribbon microphone having magnets positioned within a small gap in between pieces of opposite poles. A conductive ribbon placed in an air gap between the magnets by an adjustable ribbon holder structure. The adjustable ribbon holder structure includes two ribbon holders and a ribbon tension control. The ribbon holder can be fixed from one side by sliding on one side or sliding on both sides. The ribbon tension control adjusts the tension of the elastic ribbon. By turning the ribbon tension control, turning motion translate to linear motion and change the distance between the ribbon holders and alter the tension of the ribbon. Changing the ribbon tension also possible by different ribbon tension control mechanism by rolled or folded the ribbon in one side or both side of the microphone. The tunable ribbon microphone may have more than one ribbon, adjustable ribbon holder structure and ribbon tension control.

    摘要： A top port MEMS microphone package includes a substrate having a back volume expanding aperture therein. A MEMS microphone electronic component is mounted to the substrate directly above the back volume expanding aperture such that an aperture of the MEMS microphone electronic component is in fluid communication with the back volume expanding aperture. A lid having a lid cavity is mounted to the substrate. The back volume expanding aperture couples the aperture of the MEMS microphone electronic component to the lid cavity. By coupling the lid cavity to the aperture with the back volume expanding aperture, the resulting back volume is essentially the size of the entire top port MEMS microphone package. In this manner, the noise to signal ratio is minimized thus maximizing the sensitivity of the top port MEMS microphone package as well as the range of applications.
