By applying the sound transmission device and the detecting device, the sound features of the sound source can be tested accurately, the accuracy of the testing can be ensured; the testing process is controlled by presetting the formula to ensure that the testing can be completed automatically, thereby improving the testing efficiency.
Description
Technical field
The present invention relates to a kind of proving installation, the particularly a kind of pronunciation test device that can test automatically the pronunciation characteristics of sound source.
Background technology
Hummer is commonly called as loudspeaker, and it is a kind of pronunciation electronic devices and components that are widely used in the integral structure in the various electronic products.Hummer adopts DC-voltage supply mostly, is widely used in making microphone device in the electronic products such as computing machine, printer, duplicating machine, alarm, electronic toy, vehicle electronics, telephone set, timer.
When carrying out computer motherboard when test, pronunciation characteristics such as the pronunciation size of employed hummer on the mainboard and tonequality are tested being absolutely necessary.Have a modular circuit to control the sounding of hummer on the current computer mainboard, the positive terminal of hummer is connected to power supply by an exclusion, and negative terminals is connected to the collector of a triode.Conducting when the base stage of triode receives pulse waveform control signal from South Bridge chip, the internal circuit of hummer formed a complete loops and sounded by a microphone this moment.
Described hummer is being carried out pronunciation characteristics when test at present, the sound that the described microphone that the tester directly presses close to hummer with ear sends when listening attentively to hummer work, and judge according to working experience whether its pronunciation is normal.Yet the tester very easily is subjected to the influence of surrounding environment sound when listening attentively to the receiver pronunciation, thus can not accurately learn the actual pronunciation characteristics of hummer, thus easily cause mistake to survey erroneous judgement.
Summary of the invention
In view of foregoing, be necessary to provide a kind of pronunciation test device that can carry out automatic accurate test to the pronunciation characteristics of sound source
A kind of pronunciation test device is used for the pronunciation characteristics of a sound source is tested, and described pronunciation test device comprises a control device, a sound transmission device, an arrangement for detecting and a display device, and described sound transmission device comprises a receiving trap; Described control device emission one controls signal to the control end of described sound source so that described sound source sounding, described receiving trap receives the sounding characteristic of described sound source and is sent to described arrangement for detecting, the described pronunciation characteristics that described arrangement for detecting will receive and preset value is compared and show the detecting result in described display device.
Compare prior art, the application of described sound transmission device and arrangement for detecting can be tested the pronunciation characteristics of described sound source accurately, has guaranteed the accuracy of test, sets in advance formula and controls test process and make test to carry out automatically, has improved testing efficiency.
Description of drawings
The invention will be further described in conjunction with embodiment with reference to the accompanying drawings.
Fig. 1 is the frame principle figure of the better embodiment of pronunciation test device of the present invention.
Fig. 2 is the structural representation of Fig. 1.
Embodiment
Please jointly with reference to Fig. 1 and Fig. 2, pronunciation test device 10 of the present invention is used for the pronunciation characteristics of a sound source 20 is tested, the better embodiment of described pronunciation test device 10 comprises a control device 30, one sound transmission device 40, one arrangement for detecting 50 and a display device 60, described sound transmission device 40 comprises a receiving trap 42 and a radome 44, setting in advance formula controls 30 emissions one of described control device and controls signal to the control end of described sound source 20 so that described sound source 20 sounding, described receiving trap 42 receives the sounding characteristic of described sound source 20 and is sent to described arrangement for detecting 50, the described pronunciation characteristics that described arrangement for detecting 50 will receive and preset value is compared and show the detecting results in described display device 60, described radome 44 is arranged at the periphery of described sound source 20 to isolate ambient noise.
In better embodiment of the present invention, described sound source 20 is the hummer 24 on the mainboard 22 to be measured, described control device 30 is the South Bridge chip 32 on the described mainboard to be measured 22, described arrangement for detecting 50 is the register 52 on the described mainboard to be measured 22, and described display device 60 is a display screen 62 that links to each other with described mainboard 22 to be measured.Described hummer 24 has the positive and negative electrode terminals, and corresponding with the positive and negative electrode terminals of described hummer 24 respectively linking to each other of the positive and negative end of a microphone 26 sends with the sound with described hummer 24.One end of described mainboard to be measured 22 is provided with Mike's input (Mic-in) interface 28, and described sound source 20 also can be other pronunciation components and parts.
Described receiving trap 42 comprises a sound source wire 420 and a Mic-in interface 422 that is connected with an end one of described sound source wire 420.Described radome 44 can use plastic material, and described radome 44 is the hollow cone of the equal opening in a top and bottom, and its open top 45 is less, and bottom opening 46 is bigger.The bottom opening 46 of described radome 44 can directly be enclosed within the periphery of described hummer 24 and described microphone 26 to isolate ambient noise.
Before testing, programming writes the register 52 of the pronunciation characteristics preset value of dependence test control formula and described hummer 24 to described mainboard 22 to be measured, and the open top 45 that the other end of described sound source wire 420 is passed described radome 44 is connected to the output terminal of described hummer 24; Again described radome 44 is spurred until the periphery of seal closure at described hummer 24 and described microphone 26 along described sound source wire 420; Then, the Mic-in interface 422 of described receiving trap 42 is inserted the Mic-in interface 28 of described mainboard 22, open the power switch of described mainboard 22 and enter described test control formula.Described test control formula is controlled described South Bridge chip 32 and is sent pulse signal to the control end of described hummer 24, described hummer 24 is sounded by described receiver 26 after receiving control signal, and voice signal is sent to the register 52 of described mainboard to be measured 22 by the Mic-in interface 28 of described sound source wire 420 and described mainboard to be measured 22; Described register 52 is gathered the sounding characteristic waveforms that receives and the frequency and the amplitude of described waveform is analyzed under the control of described test control formula, then with the actual value that records with deposit preset value and compare, when the frequency of described sounding characteristic and amplitude all just often, show on the described display screen 62 that test passes through; If any unusually, then show test crash and display abnormality reason.
The better embodiment of pronunciation test device 10 of the present invention utilizes described radome 44 to isolate the noise jamming of external environment, and the voice signal that host computer is received is the accurate sound that described hummer 24 sends, thereby test result is more accurate; Simultaneously, the programming Control test process then makes test to carry out automatically, has improved testing efficiency.
