Embodiment Construction
[0031] Several specific embodiments that can effectively implement the present invention are given in the accompanying drawings of the description. In practical applications, the shape of the double voice coil and the shape of the closed mutual inductance coupling magnetic conduction loop can be designed into various variations according to the basic principles of the present invention. Figure 4 in the accompanying drawings, Figure 5 , Figure 6, Figure 7, and Figure 8 are designed mainly for mid-bass speakers, Figure 9 , Figure 10, Figure 11 , Figure 12 , Figure 13 , Figure 14 Designed primarily for mid- and high-range speakers. The specific implementation manners of the present invention will be further described in conjunction with the accompanying drawings. In order not to affect the cleanliness of the drawings, the two external connection terminals of the speaker, the connection lines between the two voice coils and the connection lines between the two voice ...
