The purpose of this utility model is to provide a kind of rationally distributed speaker system and uses the electronic equipment of this system.
The purpose of this utility model is achieved in that a kind of speaker system, it comprises loudspeaker monomer, audio frequency power amplifier and frequency modulation power amplifier, loudspeaker monomer is provided with shell, the voice coil loudspeaker voice coil that is exposed to first conducting end of shell and second conducting end and electrically connects with first conducting end and second conducting end respectively, wherein, described speaker system also is provided with first inductance, second inductance and the 3rd inductance, described first inductance links to each other with first conducting end with audio frequency power amplifier respectively, second inductance links to each other with second conducting end with audio frequency power amplifier respectively, one end of the 3rd inductance links to each other with first inductance with first conducting end respectively, and the other end links to each other with the frequency modulation power amplifier.
A kind of electronic equipment, it comprises speaker system, described speaker system comprises loudspeaker monomer, audio frequency power amplifier and frequency modulation power amplifier, loudspeaker monomer is provided with shell, the voice coil loudspeaker voice coil that is exposed to first conducting end of shell and second conducting end and electrically connects with first conducting end and second conducting end respectively, wherein, described speaker system also is provided with first inductance, second inductance and the 3rd inductance, described first inductance links to each other with first conducting end with audio frequency power amplifier respectively, second inductance links to each other with second conducting end with audio frequency power amplifier respectively, one end of the 3rd inductance links to each other with first inductance with first conducting end respectively, and the other end links to each other with the frequency modulation power amplifier.
Preferably, described speaker system also is provided with an end and links to each other with first inductance with first conducting end respectively, first electric capacity that the other end links to each other with a end away from the 3rd inductance of frequency modulation power amplifier.
Compared with prior art, the voice coil loudspeaker voice coil of the utility model loudspeaker monomer is taken into account vocal function and frequency modulation function, effectively raises the usage space of electronic equipment, realizes speaker system and uses the rational deployment of the electronic equipment of this system.
[description of drawings]
Fig. 1 is the utility model speaker system and the circuit arrangement schematic diagram of using speaker system in this system.
[embodiment]
Describe the utility model speaker system in detail and use the concrete structure of the electronic equipment of this system below in conjunction with accompanying drawing.
Please join Fig. 1, the utility model speaker system 100, it comprises loudspeaker monomer (not shown), audio frequency power amplifier 3 and frequency modulation power amplifier 4, loudspeaker monomer is provided with shell, be exposed to first conducting end 11 and second conducting end 12 of shell and be contained in the interior voice coil loudspeaker voice coil 21 of shell, these voice coil loudspeaker voice coil 21 1 ends and first conducting end 11 electrically connect, the other end and second conducting end 12 electrically connect, wherein, speaker system 100 also is provided with first inductance 13, second inductance 14 and the 3rd inductance 15, described first inductance 13 links to each other with first conducting end 11 with audio frequency power amplifier 3 respectively, second inductance 14 links to each other with second conducting end 12 with audio frequency power amplifier 3 respectively, one end of the 3rd inductance 15 links to each other with first inductance 13 with first conducting end 11 respectively, and the other end links to each other with frequency modulation power amplifier 4.
