    • 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.
    • 一种用于移动铁骨传导声音接收装置的平衡装置; 踢脚板配置成平面结构,前端有开口槽口; 两个平衡块构造成平面结构并且在基板的两侧提供对称,并且形成在每个反平衡块的前端上的开口凹口与基板的前端上的开口凹口对准。 本发明增加了其平衡装置的有效移动质量,并优化了其平衡装置占用的空间,增强了相应的移动铁骨传导声音接收装置的换能效率和输出振动水平; 控制产品尺寸; 基板分体式设计和平衡块; 降低了制造其平衡装置的难度,并通过选择不平衡块的不同厚度和形状,灵活地满足各种移动铁骨传导声音接收装置的移动质量的要求。
