It is necessary to pass the quality control test through the use of manpower by the quality control person. However, the quality of shipments is mixed. In addition, the second, it may cause the mobile phone management personnel to increase, and the competitiveness of the products will decrease as the mobile phones are mass-produced. Therefore, the cost of f-added products leads to a poor competition in the production management system and the reduction of quality control. ===Mobile products 4 M337201 [Creation content] The purpose of this creation is to provide a mobile phone test tool for control The quality of mobile phones. To achieve these and other objectives, the present creation provides a mobile phone test tool. The mobile phone includes an audio processing circuit for outputting an audio signal. This test tool includes a band pass filter and a decision circuit. Bandpass Filtering The output of the audio processing circuit is used to extract the amplitude of the audio signal in one of the specified bands. The judging circuit is coupled to the band pass filter to determine whether the mobile phone passes the quality inspection according to the magnitude of the amplitude. In accordance with the mobile telephone test tool of the preferred embodiment of the present invention, the band pass filter includes a low pass filter and a high pass filter. The low pass filter is coupled to the audio processing circuit for filtering out the amplitude of the audio signal above the specified frequency band. The high pass filter is coupled to a low pass filter for filtering out amplitudes below the specified frequency band in the audio signal. In the present embodiment, the center frequency of the specified frequency band is 217 Hz, and the audio processing circuit is a sound amplifier. The mobile phone test tool of the present invention uses a band pass filter and a judgment circuit in the circuit design to achieve the amplitude of the extracted sound signal in a specified frequency band. Therefore, the application of this creation in quality control testing can eliminate the need for manual judgment as well, and avoid the uneven quality of mobile phone shipments. In addition, this creation can also reduce the time and labor costs of product testing. In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings, 5 M337201. [Embodiment] FIG. 1 is a block diagram of a mobile phone test tool according to an embodiment of the present invention. Referring to FIG. 1, the test tool 100 includes a band pass filter 〇1 and a determining device 102. To illustrate the spirit of the present work, the block diagram also shows a mobile phone 103 of a GSM (Global System for Mobile Communications) system including an audio processing circuit 1-4. The mobile telephone 103 of the GSM system transmits data at a burst frequency of 217 Hz, thereby generating a strong electric field modulated by a 217 Ηζ frequency. However, the 217 Hz frequency is just in the audio band. Although the GSM handset operates in the 8J) 0MHz to 1900MHz frequency range, the 217Hz envelope (envelop) is fixed. According to the experimental test results, the distance between the RF circuit and the audio amplifier in the mobile phone 1 〇3 of the GSM system is less than ten centimeters, and the pickup signal appears at the output of the audio amplifier. The noise looks like a square wave of 217 Hz. Gated control of 800MHz to 19〇〇MHz RF signal. However, the current mobile phone is getting smaller and smaller, and the audio processing circuit is difficult to differ from the radio frequency circuit layout inside the mobile phone 103 by ten centimeters. > Therefore, in this embodiment, the band pass filter 101 is connected to the audio processing circuit 1〇4_ of the mobile phone 103 of the GSM system for operating the audio signal output from the audio processing circuit 104 at 217 Hz. The amplitude. The circuit breaker 102 _ bandpass filter 1〇2 is used to determine whether the mobile phone 1G3 passes the quality control test according to the amplitude of the audio signal in the 2i7Hz band. When the above amplitude is too large, the county display audio processing circuit 6
