Abstract
The utility model discloses an automobile speaker online detection device, and provides an online detection device which inputs a sound source to a speaker in an automobile through an external component. The time waste and the low production efficiency caused by the complex procedure of first installing a CD machine in the automobile and then detaching the CD machine after the detection are avoided, the operation is simple and convenient, and the work efficiency of the automobile speaker online detection is greatly increased. The automobile speaker online detection device comprises a power signal source, a power supply, a bracket and a conducting wire with a connector. The power signal source is fixed on the bracket. The conducting wire with the connector is connector between the power signal source and the speaker to be detected. The power supply is connected with the power signal source.
Description
Technical field
The utility model relates to a kind of loud speaker checkout gear, relates in particular to a kind of for the get on the car on-line measuring device of loud speaker of auto production line.
Background technology
Online detection in the auto production line upper speaker is an important step of quality testing.For the vehicle of standard configuration version, the CD main frame has been installed in the car, and whether the detection of loud speaker just can to detect loud speaker working properly if only needing that vehicle launch is opened the CD main frame; And join the vehicle of version for letter, and without the CD main frame, carry out the detection of loud speaker, need to prepare a CD main frame, and the CD main frame is installed in the car, connect power supply, loud speaker, detect complete again with its dismounting.Car is joined in letter of the every production of this metering system, all will carry out installation and the dismounting of CD main frame, wastes time and energy, and has a strong impact on production efficiency.
Open day be that on 02 22nd, 2012, publication number are that the patent documentation of CN 202150939U discloses a kind of loud speaker at thread detector, adopted controller, display, test signal generation circuit, power amplification circuit, sample circuit, impedance range Circuit tuning, A/D change-over circuit, detected the assemblies such as button, pulse amplifying circuit, loud speaker has been carried out the parameter detecting such as performance, impedance.Because auto loud hailer is all according to automobile type configuration apolegamy typing, only need carry out the whether normal detection of speaker operation on the production line gets final product, if therefore this technical scheme detects online for the auto production line upper speaker, just there are too complicated and the unconformable problem of measuring ability, use inconvenient.
Summary of the invention
The utility model main purpose is to provide a kind of auto loud hailer on-line measuring device, and it is simple in structure, easy to use, but the online operating efficiency that detects of Effective Raise auto production line upper speaker.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of auto loud hailer on-line measuring device, comprise power signal source, power supply, support and with the wire of connector, power signal source is fixedly mounted on the support, wire with connector is connected between power signal source and the tested speaker, and power supply connects power signal source.
Power signal source is fixed on the outer support of car, and power signal source carries out the audio signal of self can directly to drive loud speaker after the power amplification; To connect with wire one end of connector the tested speaker in the power signal source other end connection car, and can detect tested speaker and whether work.Convenient and easy during operation, only need to plug and unplug the online detection that loud speaker is just finished in two actions efficiently by the connector of tested speaker lead-in wire.
As preferably, power signal source is the CD machine of automobile with the radio reception head, and the audio signal output end of radio reception head connects the CD machine of automobile built-in power amplifier.General CD machine of automobile all includes the radio reception head, and CD player carries power amplifier, the audio signal that the radio reception head receives direct promotion tested speaker sounding through the CD player power amplifier after.
As preferably, suitable with wire one termination plug-in unit and the CD machine of automobile power signal output connector of connector, other end connector and tested speaker lead-in wire connector are suitable.
As preferably, the radio reception head is connected with car antenna.So that the output of audio power signal is more stable.
As preferably, power supply is the AC/DC power supply, and the AC/DC power input voltage is the alternating current 220V civil power, is output as the 12V direct current.12V DC power supply and CD machine of automobile working power are complementary.
The beneficial effect that the utility model brings is, provide a kind of by the on-line measuring device of outer relay part to internal loudspeaker input source of sound, avoided first CD player being installed in the car, detected complete time waste and the production efficiency that the more loaded down with trivial details operation of its dismounting is caused and reduce.Install simple, conveniently, greatly improved the online testing efficient of auto loud hailer.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: the 1st, power signal source, the 2nd, support, the 3rd, power supply, the 4th, with the wire of connector, the 41st, tested speaker termination plug-in unit, the 42nd, CD machine of automobile termination plug-in unit, the 5th, car antenna, the 6th, city's electric connection line, the 7th, fixing angle bar, the 8th, set bolt.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, the utility model is a kind of auto loud hailer on-line measuring device.Power signal source 1 is the CD machine of automobile with radio reception head and built-in power amplifier; CD machine of automobile is by fixedly angle bar 7 and set bolt 8 are fixed on the support 2; The input of power supply 3 by city's electric connection line 6 be connected to the 220V AC power, output 12V direct current is connected to the CD machine of automobile power input; Car antenna 5 connects the radio reception head; Wire 4 with connector is that long lead connects connector 42(male with convenient) be connected connector 41(male with CD machine of automobile connector (female)) cooperate with loud speaker connector (female end) in the automobile and join.
When loud speaker detected online, the radio reception head was fixed on a certain frequency of radio station, made it the stable output audio signal, connector 41 is connected on the internal loudspeaker lead-in wire connector, can judge immediately loud speaker and whether work, pull out connector 41 after detection is finished, finish one-time detection.
So the utlity model has following characteristics: join on edition auto production line in letter, avoided first CD player being installed in the car, detected the complete time waste that the more loaded down with trivial details operation of its dismounting is caused and production efficiency has been affected, install simple, conveniently, greatly improved the online operating efficiency that detects of auto loud hailer.
