Abstract
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.
