Should be noted that, if adopt existing common inductance coil tandem on the high frequency network circuit of three frequency division frequency divider, perhaps inductance coil L1 of the present invention is oppositely connected, will not only can not realize purpose of the present invention, and its acoustics will be poorer than existing frequency divider.
Through test of many times, inductance coil L1 of the present invention is connected in series on the high frequency network of three frequency division frequency divider, can make its supporting audio amplifier have following good effect:
(1) sound that high pitch is sent is active, melodious.
(2) statement of the voice that send of intermediate frequency and musical instrument is bright, clear.
(3) low frequency has enough electric currents, makes low frequency send solid strong rubadub.
Use the audio amplifier of frequency divider of the present invention, the sound that plays back, overall sound field intelligibility of speech height, various musics are well arranged, and sound is bright and clear, melodious, brings light, happy sensation to the hearer.
The present invention provides the inductance coil of special construction to be applied on the high frequency network circuit of three frequency division frequency divider, and traditional being connected in parallel is connected in series instead, obtains satisfied effect, is outstanding characteristics of the present invention.
