摘要： A speaker driving device applies a constant voltage of a constant voltage source to a pair of voice coils alternatively by switching the direction of applying the constant voltage based on a binary PDM signal. A .DELTA..SIGMA. modulator produces the binary PDM signal by .DELTA..SIGMA.-modulating a digital audio signal from a digital low-pass filter. The constant voltage is applied to a first voice coil in one direction and is applied to a second voice coil in the reverse direction by switching the direction of applying the constant voltage. The first and second voice coils forms the pair of voice coils. This arrangement causes a current to flow through the first and second voice coils in opposite directions and a diaphragm of a speaker to be driven in two directions opposite to each other. As a result, the speaker is driven more efficiently. Moreover, since the switching of the direction of applying the constant voltage is performed by changing the connections between the constant voltage source and the pair of voice coils, a switching circuit with a simplified structure is used.

摘要翻译： 扬声器驱动装置通过基于二进制PDM信号切换施加恒定电压的方向，将恒定电压源的恒定电压交替地施加到一对音圈。 DELTA SIGMA调制器通过DELTA SIGMA产生二进制PDM信号，从数字低通滤波器调制数字音频信号。 恒定电压在一个方向施加到第一音圈，并且通过切换施加恒定电压的方向在相反方向上施加到第二音圈。 第一和第二音圈形成一对音圈。 这种布置使得电流在相反的方向上流过第一和第二音圈，并且扬声器的振膜在彼此相反的两个方向上被驱动。 因此，扬声器的驱动效率更高。 此外，由于通过改变恒压源与一对音圈之间的连接来进行施加恒定电压的方向的切换，所以使用具有简化结构的开关电路。

摘要： Developing bias is set as follows. An electric field intensity between a developing roller and a photoconductor is set to cause normally-charged toner to fly in an image area and not to cause the toner to fly in a background area. Thus, the normally-charged toner does not fly in the background area. The normally-charged toner caused to fly is therefore unlikely to flick low-charged toner and oppositely-charged toner. The low-charged toner and the oppositely-charged toner will not adhere to the background area and cause image fogging. Accordingly, an image forming apparatus can be provided to prevent the low-charged toner and the oppositely-charged toner from adhering to the background area of an electrostatic latent image on the photoconductor and to avoid the occurrence of image fogging in the background area on a printed material.

摘要： A bass enhancing device for a speaker system a bass enhancing member that increases base range sound waves by vibrating according to sound waves emitted by a speaker unit. The bass enhancing member has a bass range resonant frequency that differs from a frequency at which an amplitude of vibration speed of the speaker system becomes largest. Further, vibration detecting device for detecting vibrations of the bass enhancing member and releasing a detecting current is provided, for example, in the bass enhancing member. The detecting current is fed back to amplification device by feedback device.
