The type horn system of band tally function
Technical field
The present invention relates to the stereo set field, relate in particular to type horn equipment.
Background technology
The relay of car horn all is coil contact and static iron core structure at present.Relay contact produces magnetic field (electromagnetic force) by coil; closure is inhaled once in the contact; loudspeaker pipe once; the product of the method for designing manufacturing of this mechanical type conversion is short serviceable life; the quality instability burning of contact often occurs and does not work, and loudspeaker are under intact situation; the relay malfunction; do not play the protection loudspeaker, thereby shortened the mission life of loudspeaker, and because of its fault of construction; outward appearance is not novel; after the contact was subjected to moisture effect, its frequency was extremely unstable, causes loudspeaker not worked and brings many difficulties; and can only can not make the sound of loudspeaker change into multiple with single sound work.
Summary of the invention
The technical problem to be solved in the present invention is: existing car horn is short serviceable life, quality instability, outward appearance are not novel, the deficiency that sound is single, a kind of long service life is provided, steady quality, outward appearance novelty, the type horn system that sound is abundant, and this horn system band tally function, the access times of loudspeaker and current sound type are shown on the charactron, and switch key, following switch key switch sound type, easy switching in the use.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of type horn system with tally function comprises with the lower part: controller, contact loudspeaker, loudspeaker trigger line, horn wire, cathode power supply line, anode power cord, loudspeaker gauge tap; The contact loudspeaker are connected with controller by horn wire; The loudspeaker gauge tap triggers line by loudspeaker and is connected with controller; The cathode power supply line is connected with the contact loudspeaker with controller, and anode power cord is connected with controller; The cathode power supply line also is connected with the positive pole of outside accumulator, and anode power cord also is connected with the negative pole of outside accumulator.
Preferably, in the technique scheme, the contact loudspeaker are two, and one is loudspeaker, and another is a bass horn; Horn wire also is two, and one is the loudspeaker line, and another is the bass horn line; Loudspeaker is connected with controller by the loudspeaker line, and bass horn is by bass horn line and controller.
Further preferred, in the technique scheme, controller comprises with the lower part: voltage regulation unit, digital driver element, digital display unit, microprocessor, EEPROM, power drive unit; Voltage regulation unit is used to provide the galvanic current source; Digital driver element is used to drive digital display unit; Digital display unit is used to show the access times of contact loudspeaker; Power drive unit is used to drive connected contact loudspeaker; Microprocessor is used to control the access times that digital display unit shows the contact loudspeaker; EEPROM is used for forever preserving the access times of contact loudspeaker.
Further preferred, in the technique scheme, controller also comprises with the lower part: go up switch key and following switch key; Last switch key and following switch key are used for the current sound type of double-throw contact loudspeaker; Digital display unit also is used to show the current sound type of contact loudspeaker; Microprocessor also is used to control the contact loudspeaker by current sound type sounding; EEPROM also is used for forever preserving the current sound type of contact loudspeaker.
The invention has the beneficial effects as follows:
1. controller of the present invention has adopted the technology of microprocessor and transistor electronic control circuit, broken traditional mechanical arrangement works pattern,, improved the work number of times with the pronunciation of rational electronic type frequency stabilization structure output control loudspeaker, take turns to operate about compound horn, improve serviceable life.Under the normal condition, disposed the loudspeaker of controller of the present invention, its mission life reaches more than 100000 times, prolong happy work number of times, and original mechanical loudspeaker mission life national standard is 50000 times, and has arrived back need replacing loudspeaker in the mission life of loudspeaker, does not need more changer controller.
2. microprocessor and transistor electronic control circuit have replaced the traditional mechanical structure, the volume of controller of the present invention is all reduced significantly, profile can not received the inner body influence and bad control yet as traditional product, so controller of the present invention can use novel more profile.
3. the life-span number of times of loudspeaker operate as normal of the present invention is recorded in EEPROM and goes up and can forever preserve, and selects the button of speaker sound type to switch by easy on and off.

Fig. 2 is the inner structure synoptic diagram of the type horn system controller of band tally function of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
Embodiment
As shown in Figure 1, the type horn system of band tally function comprises with the lower part: controller 1, contact loudspeaker 2, loudspeaker trigger line 3, loudspeaker line 4, bass horn line 5, cathode power supply line 6, anode power cord 7, loudspeaker gauge tap 8.
Contact loudspeaker 2 are two, and one is that loudspeaker passes through loudspeaker line 4 and is connected with controller 1, and another is that bass horn passes through bass horn line 5 and is connected with controller 1, and loudspeaker trigger line 3 and link together with controller 1.
Cathode power supply line 6 is connected with contact loudspeaker 2 with controller 1, and anode power cord 7 is connected with controller 1.Cathode power supply line 6 is connected with the positive pole of outside accumulator, and anode power cord 7 is connected with the negative pole of outside accumulator.
Loudspeaker gauge tap 8 triggers line 3 by loudspeaker and links together with controller 1.
Controller 1 outside is a housing, and digital display unit is installed on the housing, and goes up switch key and following switch key.
As shown in Figure 2, controller 1 inside comprises with the lower part: voltage regulation unit, digital driver element, digital display unit, microprocessor, EEPROM, power drive unit.
Voltage regulation unit is used to provide galvanic current source other parts to controller 1 inside, as the 12V direct current from outside accumulator is converted to the 5V direct current.
Digital driver element is used to drive digital display unit.
Digital display unit is used to show the access times and the current sound type of contact loudspeaker 2.
Power drive unit is used to drive connected contact loudspeaker 2.
Last switch key and following switch key are used for the current sound type of double-throw contact loudspeaker 2.
Microprocessor is used to control number demonstration and contact loudspeaker 2 which kind of sound type sounding of use of digital display unit.
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a kind of EEPROM (Electrically Erasable Programmable Read Only Memo), is used to store the access times and the current sound type of contact loudspeaker 2, and can forever preserves.
The above embodiment is the preferred embodiment that proves absolutely that the present invention lifts, and protection scope of the present invention is not limited thereto.Being equal to that those skilled in the art are done on basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
