Description

Detection system Technical Field The invention relates to a weight classification system, in particular to a detection system for a loudspeaker vibrating reed. Background The general loudspeaker comprises a bass unit, a midrange unit and a treble unit, and the three units are respectively responsible for different frequencies. A typical moving coil loudspeaker produces an electromagnetic field when current flows through the wire to the voice coil, which causes the moving coil to be forced into the gap due to the electromagnetic field being oriented at right angles to the magnetic field of the permanent magnets on the loudspeaker. The mechanical force generated by the motion can make the paper disc attached with the voice coil vibrate vertically and up and down, so that air vibrates, and the emitted sound frequency is transmitted to the human ear, thereby achieving the purpose of sound reduction for human listening and realizing the conversion from electric energy to sound energy. In order to avoid the voice coil in the loudspeaker from contacting other metal components due to vertical and up-down vibration, various nonmetallic part substrates contained in the loudspeaker are made of cloth materials, and the main reason is that the cloth materials subjected to special treatment have proper elasticity and strength and can provide the requirements of functions required during the operation of the loudspeaker, wherein the loudspeaker vibrating piece (or called a Damper) is taken as one of the most important components in the loudspeaker or the loudspeaker structure, and besides providing the better output power and audio characteristics of the loudspeaker or the loudspeaker, the loudspeaker vibrating piece is also the basis of quality management when a loudspeaker or a loudspeaker manufacturer manufactures the loudspeaker or the loudspeaker. The manufacturing method of the prior art speaker vibration piece includes an impregnation step, a baking step, a hot pressing step and a cutting step. Wherein, the impregnation step impregnates the cloth in the resin, so that the cloth absorbs the resin and forms a resin layer outside the fiber of the cloth, thereby making the cloth have a certain hardness. The baking step dries the cloth absorbing the resin to remove moisture in the cloth. However, the manufacturing method of the speaker membrane of the prior art has a problem in that when the semi-finished speaker membrane is subjected to the hot pressing step, the cloth may not be completely adhered to the surface during transportation, thereby causing uneven surface of the speaker membrane after hot pressing or defects such as groove marks, and causing noise during outputting audio, thereby affecting the sound quality of the speaker. On the other hand, if the problem of the surface roughness of the speaker vibrating reed or the occurrence of flaws such as groove marks is not solved, the metal wire cannot be firmly connected with the voice coil and the input terminal due to the vibration of the vibrating plate for a long time, thereby affecting the output of the speaker sound quality, and the wire is more likely to be deformed, loosened or broken due to the problem of dislocation. Disclosure of Invention The main objective of the present invention is to provide a detection system, wherein the detection system is capable of achieving the effects of saving space, saving labor, and reducing labor intensity by controlling the control unit of the detection system by one person through the measurement unit and the classification unit, wherein the measurement unit and the classification unit are used for classifying the speaker vibrating reed according to the weight interval, and in addition, the uneven surface of the speaker vibrating reed causes the weight of the speaker vibrating reed to change. The invention provides a detection system suitable for an environment for automatically classifying a plurality of loudspeaker vibrating pieces, which comprises a control unit, a measuring unit and a classifying unit, wherein the control unit is used for controlling the detection system, the measuring unit is coupled with the control unit and is used for measuring and generating weight information of the plurality of loudspeaker vibrating pieces, and the classifying unit is coupled with the control unit and classifies the plurality of loudspeaker vibrating pieces according to at least one weight interval and the weight information. Preferably, according to the detecting system of the present invention, when the weight of the speaker vibration piece falls within the weight range, the classifying unit determines that the weight of the speaker vibration piece is correct and generates correct information, and when the weight of the speaker vibration piece does not fall within the weight range, the classifying unit determines that the weight of the speaker vibration piece is incorrect and generates error information. Preferably, the dete
