[Previous technology] According to the current development of electronic technology and the improvement of social and economic level, consumer electronic products such as earphones and mobile phones have been widely used, which brings great convenience to people's work, study and entertainment. Speakers for current consumer electronics typically include a basin frame assembly and an audio component. The basin frame assembly includes a basin frame and the sounding assembly includes a sound film, a retaining ring and a voice coil. An inner lead is drawn from the voice coil, and the inner lead has a fixed point on the fixed ring and is finally led out from the fixed point. When the current speaker is manufactured, the inner lead is fixed on the fixing ring after being covered on the film surface of the sound film; then, after the basin frame assembly, the sounding component and the mesh cover are completely bonded and fixed, the battery is refilled. Magnetic and then perform performance testing. However, due to the limitations of the structure of the basin frame, the sound film and the retaining ring, most of the inner leads are attached to the sound film to avoid abnormal sound and improve the life of the inner lead. However, due to the influence of the inner lead bonding limitation, the sound film often has problems such as poor sound performance and serious distortion in a certain frequency range. For example, a headphone speaker is prone to full-frequency distortion peaks in the 300-500 Hz band, with a distortion of 1.0%, a weight of 10%, and a full-frequency distortion peak of more than 3%, totaling about 10%. 5 1335770 The performance test of the current speaker is generally carried out until the assembly is fully fixed. Once the problem of full-frequency distortion is found, the remedial measures are limited and the effect is not satisfactory, and the product is often scrapped. SUMMARY OF THE INVENTION A first object of the present invention is to overcome the deficiencies of the prior art described above, and to provide a speaker with less inner conductor and sound film that can be attached or not attached, thereby improving sound performance, especially reducing the rate of defective products of full frequency distortion. . Another object of the present invention is to provide a method of manufacturing a speaker which can be bonded and fixed after the product has been tested to improve the product yield. To achieve the above first object of the present invention, a speaker provided by the present invention includes: a basin frame assembly including a basin frame having a basin frame notch; a sounding component including a voice coil, the voice coil leading to an inner lead, the inner lead It is taken out from the gap of the basin frame and fixed at the gap of the basin frame. In order to achieve the above second object of the invention, the speaker manufacturing method provided by the present invention comprises the following steps: (1) assembly of the basin frame assembly; (2) magnetization of the basin frame assembly; (3) assembly of the pronunciation component; (4) sound component The inner lead is fixed at the gap of the basin frame of the basin frame, and the basin frame assembly, the sounding component and the magnetic mesh cover are magnetically attracted by the basin frame assembly; (5) the pronunciation performance test is performed, and the performance is up to the next step directly. 6 1335770; If the performance is not up to standard, directly adjust and test until the performance is up to standard; (6) Bond the bracket assembly, the sounding component and the magnetic mesh cover. As described above, since the inner lead of the speaker of the present invention is taken out from the gap of the basin frame of the basin frame and fixed at the outer edge of the gap of the basin frame, the inner lead wire can be pulled to tend to leave the sound film, and no sound film or less stickers can be attached. The sound-damping film reduces the influence on the vibration of the sound film, thereby improving the sounding effect. In the manufacturing method of the speaker of the present invention, the product performance test is performed in the magnetic attraction state of the basin frame assembly, the sounding component and the magnetic mesh cover, and once the performance is not up to standard, the basin frame assembly and pronunciation can be adopted. The components are relatively moved to adjust the relative positional relationship between the inner lead and the sound film to change the sound performance, and directly test, so that the product performance can be effectively improved and the product manufacturing pass rate can be improved.
