Embodiment Construction

[0051] Please refer to image 3 , which shows a block diagram of a speech module function detection device provided according to a preferred embodiment of the present invention. The detection device of speech function comprises signal generator 310, switch device 320 and speech signal detector 330 etc., wherein speech signal detector 330 is equipped with peak detector 334 and frequency detector 335, is used for measuring the peak value of speech signal respectively (peak value) and frequency. The switch device 320 has switches A1, A2, ... AM coupled to the input terminals IN1, IN2, ... INM, the conduction state of the switch can be determined according to the control signal CTRL, so that the voice signal can be fed into the selected input terminal, and enter Uplink channel UPP. In addition, the switch device 320 also has switches B1, B2, ... BN coupled to the output terminals OUT1, OUT2, ... OUTN, the switches also determine the conduction state according to the control sign...

Abstract

The invention relates to a speech sound function detection device. It includes signal generator, switching device, and voice signal probe unit. The switching device is set many switch to connect the input and output end of the speech sound module. The voice signal is inputted into the speech sound module by the given input end according to the demand in actual detection, and outputted by the given output end. The signal generator includes oscillator, frequency divider, low pass filter and attenuator. After the base frequency signal generated by the oscillator is divided frequency by the frequency divider, fed in the low pass filter to filter the waves, then voice signal with different frequency is generated. The voice signal is declined with different degree by the attenuator, which means the voice change can be simulated. The voice signal probe unit includes peak valve probe unit and frequency probe unit which are used to detect the peak valve and the frequency of the voice signal. The advantage are low cost, simple operation.

Description

technical field [0001] The invention relates to a detection device, in particular to a function detection device of a voice module. Background technique [0002] In recent years, the rapid development of communication technology, whether it is mobile phones, automobiles or various types of communication equipment, can be seen in the application of GSM / GPRS voice modules. When producing a voice module, in order to test the audio function of the module, the production line must use a coaxial cable (coaxial cable) to connect the module to be tested to a test machine for testing. The test machine is, for example, the Agilent8960 GSM Test Set. [0003] Please refer to figure 1 , which shows the situation of using the test machine to detect the voice module. During measurement, the test machine 120 feeds the voice signal AS into the voice module 110 through a coaxial cable, and then the voice signal AS returns (loop back) to the test machine through the uplink path and the downl...
