Specific embodiment

Below by specific embodiment and in conjunction with attached drawing, the utility model is further described in detail.

Referring to Fig. 1, the utility model is a kind of to provide the car horn of two kinds of work volumes, including trebling circuit, it should Trebling circuit includes the power supply 1 being sequentially connected in series, conducting wire, the first fuse 2, horn switch 3, the first relay 4 and the first loudspeaker 5, it further include the bass circuit being connect with the first loudspeaker 5 or the bass circuit being connect with the second loudspeaker, the horn switch 3 is more Contact switch, the horn switch 3 include normal open switch 310 and normally closed switch 320, the normal open switch 310 and trebling circuit string Connection, for controlling the on-off of trebling circuit electric current, the normally closed switch 320 is connected with bass circuit, for controlling bass circuit The cathode of the on-off of circuit, the trebling circuit and bass circuit in parallel, the power supply 1 and the first loudspeaker 5 directly connects with vehicle frame Connect i.e. minus earth.

When needing high-pitched speaker, horn switch 3 is depressed, normal open switch 310 is connected at this time, and electric current is flowed out from power supply through the The coil of the 3 to the first relay of horn switch 4 on one fuse 2, steering wheel, at this time coil be powered generate magnetic force by first after The normally opened contact of electric appliance 4 is attracted, and route is connected, and electric current flows into loudspeaker, and the electromagnetic coil in loudspeaker generates vibration, sending sound Sound.

Embodiment one

The bass circuit includes the second fuse 6, key switch 7, normally closed switch 320, the when connecting with the first loudspeaker 5 Two relays 8 and current limliting divider resistance 9, the contact of second relay 8 are normally-closed contact, the power supply 1, the second fuse 6, key switch 7 is sequentially connected in series, and the normally closed switch 320 is connected with the coil of the second relay 8, normally closed switch 320 and second The normally-closed contact of relay is in parallel, and the cathode of second relay 8 connect i.e. minus earth, second relay with vehicle frame 8 normally-closed contact, current limliting divider resistance 9, the first loudspeaker 5 are sequentially connected in series, and when key switch 7 disconnects, the bass circuit is not Work, electric current pass in and out loudspeaker 5 by trebling circuit；

When key switch 7 is closed, electric current passes through the second fuse 6, key switch 7, normally closed switch 320, the second relay The coil of device 8 is powered, and the normally-closed contact of the second relay 8 disconnects at this time, when needing woofer, touches horn switch 3 Normally closed switch 320 is disconnected, 8 normally-closed contact of the second relay restores closed state, and the electric current flowed out from power supply 1 is through the second fuse 6, key switch 7, the second relay 8 are closed contact, current limliting divider resistance 9, finally enter loudspeaker 5, due to current limliting divider resistance 9 effect, the electric current into loudspeaker 5 is lower, therefore the volume of car horn 3 may be adjusted to lower decibel.

Embodiment two

When being connect with the second loudspeaker 12 the bass circuit include the second fuse 6, key switch 7, Voltage stabilizing module 10, often The 320, second relay 8, music drive module 11 and the second loudspeaker 12 are closed in make and break, and the contact of second relay 8 is normally closed Contact, the cathode of second relay 8 connect i.e. minus earth with vehicle frame, and the Voltage stabilizing module 10 is for exporting one group for low The low-tension current of sound circuit work, the cathode of the Voltage stabilizing module 10 connect i.e. minus earth with vehicle frame, and the power supply 1, second is protected Dangerous silk 6, key switch 7 and Voltage stabilizing module 10 are sequentially connected in series, and the normally closed switch 320 is connected with the coil of the second relay 8, often 320, the normally-closed contacts of second relay 8, music drive module in parallel with the normally-closed contact of the second relay 8 are closed in make and break 11, the second loudspeaker 12 are sequentially connected in series, and the Voltage stabilizing module 10 is electrically connected by conducting wire with music drive module 11, the pressure stabilizing Module 10 is that music drive module 11 provides operating current by the conducting wire between music drive module 11, described equipped with normally closed Switch 320, the second relay 8 circuit be signal trigger circuit, it is one high electric the purpose is to be provided for music drive module 11 Flat trigger signal, makes music drive module 11 that the second loudspeaker be driven to play, and 11 cathode of music drive module is connect with vehicle frame That is minus earth, when key switch 7 disconnects, the bass circuit does not work, and electric current passes in and out loudspeaker 5 by trebling circuit；

When key switch 7 is closed, electric current enters pressure stabilizing mould by the second fuse 6, key switch 7 from the outflow of power supply 1 Block 10, stabling current a part that Voltage stabilizing module 10 exports at this time enter music drive module 11 by conducting wire and drive mould for music Block 11 works, and the stabling current another part exported from Voltage stabilizing module enters the line of the second relay 8 by normally closed switch 320 Circle, when the coil of the second relay 8 is powered, the normally-closed contact of the second relay 8 is since electromagnetic action disconnects, and then bass circuit It can not work, when needing woofer, normally closed switch 320 can be disconnected by touching horn switch 3, at this time the second relay 8 Coil just passes through without electric current, and the normally-closed contact of the second relay 8 restores closed state, and the electric current exported from Voltage stabilizing module 10 is logical The normally-closed contact for crossing the second relay 8 enters music drive module 11, to give 11 1 height of music drive module flat triggering letter Number, the second loudspeaker 12 of driving play music or bass for reminding passerby.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Those skilled in the art Various modifications or additions are done on the basis of the utility model or are substituted in a similar manner, without departing from this reality With novel structure or beyond the scope defined by this claim, the protection category of the utility model should belong to.
