20150156582 | COUNTER BALANCING APPARATUS FOR MOVING-IRON BONE-CONDUCTED SOUND RECEIVING DEVICE - A counter balancing apparatus for moving-iron bone-conducted sound receiving device; the baseboard is configured in a planar structure, with open notch on its front end; two counter-balancing blocks configured in a planar structure and provide symmetry on both sides of the baseboard, and an open notch formed on the front end of each of the counter-balancing blocks aligns with the open notch on the front end of the baseboard. The invention increases effective moving mass of its counter balancing apparatus and optimizes space occupied by its counter balancing apparatus, enhancing transduction efficiency and output vibration level of the corresponding moving-iron bone-conducted sound receiving device; controlling the product size; the baseboard split type design and counter-balancing blocks; reduces difficulty of manufacturing its counter balancing apparatus, and flexibly meets the requirement of moving mass for various moving-iron bone-conducted sound receiving devices by selection of different thickness and shapes of counter-balancing blocks. | 06-04-2015 |
20140314253 | VIBRATION CONDUCTION AND FREQUENCY-SELECTIVE AMPLIFICATION DEVICE FOR A MOVING-IRON MICROPHONE/TRANSDUCER - A vibration conduction and frequency-selective amplification device for a moving-iron microphone/transducer, including connecting portions at both ends and a middle portion for vibration conduction and frequency-selective amplification. The device is mechanically connected to a microphone armature and a vibration diaphragm of the moving-iron microphone/transducer, and performs frequency-selective amplification on a vibration generated by the armature and transmits the vibration onto the diaphragm by the middle portion, so as to achieve frequency-selective amplification and conversion from mechanical energy to acoustic energy. The device includes a frequency-selective amplification function, and may adjust mechanical configurations and connecting portions according to different requirements to enrich the product functions and widen the scope of application, and an improved structure and means of connection, which enhances bonding strength at the connection joint, increases resistance of the product to electric and mechanical shocks, so that the service life of the product is prolonged. | 10-23-2014 |
20130170674 | MOVING IRON UNIT FOR LOUDSPEAKERS - This invention provides a moving iron unit for loudspeakers, which includes coil, iron core, diaphragm, and magnet, among which, the iron core is disposed in the coil, and the magnet is connected to the diaphragm on a transmission basis. It is characterized in that it also includes vibrating ring, to which the magnet is secured, and which is secured to the inner wall of a shielded cavity through its elastic body disposed radially, and which is connected to the diaphragm on a transmission basis through the transmission rod. Further, the unit comprises two diaphragms, which are disposed symmetrically at two sides of the vibrating ring and connected respectively to the vibrating ring on a transmission basis through a transmission rod. The coil is shaped directly by coiling on the iron core. | 07-04-2013 |
