Wash the speaker into a sound speaker ----- Speaker DIY

Wasper speaker with waste speaker Author: Ma Guiting In the 1980s, the Aihua SX-N990 is one of the cases. With the changes in the age, this speaker has long been quit the speaker stage. One day, when the author is going to deal with the speaker, I am missing the host, but is the two speakers reuse? So how to transform and grind, becoming the first priority in the project. The speaker size is 190mmx220mmx300mm, the box is made of 1 cm thick tight wooden slag, better sealing, beautiful appearance, seemingly three divided, actually two-point frequency. A treble is used for decoration. A 5-inch bass and a carton small medium tall trone. First, the cabinet is transformed. The cabinet structure is relatively reasonable, and the medium and high tone is completely isolated from the bass, and there is no inquiry problem. The inner cavity is supported with 20 mmx20mm wood strips, and the sound absorbing cotton is bonded. I used the sealed cotton used in the air-conditioning duct flange. The material is 3mm thick, and there is a single side with viscosity, more convenient to make, and good effect. Next, two speakers are evaluated, all of which are used, but appropriate modifications are required. It is mainly to increase its power tolerance. The method is to be critical to the homogeneous amount of glass glue, the uniform amount of glass glue and the thickness of the glass glue, and the thickness of the glass glue. After the glass is dried. The debugging of a single speaker is performed to see that it is in the case of a power, the amplitude of the carton vibrates and the listening sensitivity of the bass. The paint diluent can be used to correct the thickness and uniformity of the glass glue during debugging until satisfaction. Another addition of a small treble, collecting two JBL small trebles, 15 yuan / only in the old goods market. The size is very small, which is in line with the original decorative treble. Finally, the divider is transformed into a three-point frequency (see the accompanying drawings). After all are completed, it is quiz that the author is unexpected, the bass is thick, the middle sound is transparent, the treble is delicate, and the audio of the speaker with thousands of yuan is not bad. I can't think of a 50 yuan, I have such a good performance, and I have a burning friend may wish to try.
