| 内容記述 | Frequency response of the moving coil loud speaker in the current drive and voltage drive methods has been investigated. It is shown that, in the case of current drive, the low cut-off frequency is f0= (k/m)1/2π, and the high frequency response is limited only by the cut-off frequency fA of the accoustic impedance of air. On the contrary, in voltage drive, the frequency response is much complicated : It has another high frequency cut-off at ωRL=R/L, along with fA, where R and L are the voice coil resistance and inductance, respectively. When R increases, ωRL increses, but Q decreses, and when Bl increses. the efficiency increses, but Q decreses, in the case of voltage drive. The reduction of the piston radius increses the high frequency cut-off frequency in the case of current drive, but the reduction of the piston radius does not necessarily improve the high frequency response in the case of voltage drive. | |||||||
