Abstract
The utility model discloses a new on-board acoustic power amplifier output circuit wafer which comprises a last stage power amplifier output end, a sound system connection end. The last stage power amplifier output end is connected with the sound system connection end by conductor. The utility model has the advantages of: the last stage power amplifier output end is connected with the sound system connection end by conductor, the cross section of the conductor is larger than that of the clutch gold connection of the traditional circuit wafer, which makes the signal current output by the power amplifier pass through smoothly, restores the output power of the amplifier system, optimizes sound quality and promotes the play effect of music.
Description
Technical field
The utility model relates to a kind of wiring board, especially relates to a kind of novel vehicle-mounted sound power amplifier outlet line plate.
Background technology
The major function of printed substrate provides being electrically connected mutually between every electronic devices and components.Along with electronic equipment becomes increasingly complex, the part that needs is more and more naturally, and circuit and part on the printed substrate are also more and more intensive.Existing vehicle audio equipment all is SMD part and the miniature compact design of circuit, sound system final stage power amplifier output to the circuit board Copper Foil link width between the wiring plug-in unit generally about 1mm, Copper Foil line thickness is between 20-30um, in theory can be by the electric current about 1A, Copper Foil line narrow on the power amplifier outlet line plate has determined maximum output current, in fact the signal of vehicle audio sound equipment power amplifier output line through power amplification after, according to vehicle-mounted voltage is 12V, the power of power amplifier is 20W, formula P=U
2/ I as can be known, its current value is more than 7A, the power output that this bottleneck of Copper Foil line has been wasted power amplifier on hence one can see that the traditional power amplifier outlet line plate has limited the dynamic change and the tonequality reduction of music signal, serious deterioration the result of broadcast of music.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can reduce the due power output of power amplification system, promoted the novel vehicle-mounted sound power amplifier outlet line plate of music effect.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of novel vehicle-mounted sound power amplifier outlet line plate, comprise final stage power amplifier output, stereo set terminals, be connected with plain conductor between described final stage power amplifier output and the described stereo set terminals.
Described plain conductor is coating insulator outward
Described plain conductor is a copper conductor.
The cross section of described plain conductor is a flat.
The current flux of described metallic conductor is 7A～15A.
The current flux of described metallic conductor is 9A.
Compared with prior art, advantage of the present utility model is to be connected with lead between final stage power amplifier output and the stereo set terminals, it is bigger that the conductive wire cross-section area is compared traditional circuit board Copper Foil line cross-sectional area, can allow the signal code of power amplifier output pass through smoothly, the due power output of reduction power amplification system, optimization tonequality have promoted the music effect.
Lead is a metallic conductor, and the material of described metallic conductor is a copper.The resistivity of copper is less, and the loss of signal is less.
Described metallic conductor cross section is a pancake.Cross section is that the surface area of the lead of flat is circular lead much larger than the cross section of the equal volume of routine, according to the skin effect of high frequency ac signal as can be known, the transmission of the big more conductor signal of surface area is unobstructed more, and it is better for circular conductor signal laser propagation effect that cross section is that the lead of flat is compared conventional cross section.
