Longfei 310 radio's external magnetic speaker, 8 ohm 2 watts, the sound is dry and no level, so I bought 3 internal magnetic speakers online, 2 watts 1 watt 0.5 watts, the result disappointed me, not as good as the sound quality of the original speaker. Fig.2 Rummaging through the cabinet and finding a pair of disassembly speakers of a pair of small speakers, connecting the audition turned out to be beyond expectations, and it is it!Fig.3 However, this small speaker has a shell, and the thickness of 1.8 cm affects the normal installation, so the shell can only be removed. Fig.4 The horn of the rear shell is only 1 cm thick, Fig.5 According to the size of the original horn (diameter 4.5 cm), the plastic shell of the horn is properly trimmed. Fig.7 When removing the horn of the original machine, do not use a screwdriver to remove it violently, you can use a knife to draw a circle along the edge of the horn to separate the fixed yellow glue, and the horn is very easy to remove. Figure 8 Comparison of the size of the small speaker and the original speaker. Fig.9 Select the installation position of the horn and fix it with a hot melt rod. After a simple test, this 8 ohm 3 watt small speaker, vocals and music are very good!
