It states the invention was intended to provide a combined finger rest and magnetic pickup for string musical instruments; 国家的发明的目的是提供一个结合手指休息和磁感应乐器字符串;
In a non-linear non-diagonal GMI sensor for weak magnetic field, the pickup coil parameters, including the length, the diameter of coil tube, the number of turns as well as the diameter of the coil wire, in relation to the sensor sensitivity are investigated. 研究了非线性非对角化GMI传感器的信号拾取线圈参数对传感器灵敏度的影响.这些参数包括线圈的长度,线圈的直径,线圈的匝数以及线圈所用漆包线直径。
