When consumers buy a China TG149 speaker, they should not only look at the appearance, but also pay attention to the actual effect of the sound effect of the speaker. How to distinguish the sound quality of the speaker? TG149 speaker manufacturers recommend three simple measures: look, touch, and listen.

Look to see if there is a gap between the diaphragm and the panel. To distinguish the quality of speakers that are identical in appearance, the best practice is to check whether there is a gap between the diaphragm and the panel. Generally speaking, due to the high-speed operation of the China TG149 speaker, the diaphragm vibrates due to the high-speed operation, and the manufacturer generally leaves a gap between the diaphragm and the panel.
Touch to see if the diaphragm is soft to the touch. Touch the diaphragm of the TG149 speaker with your hand and feel a thin layer. There are also many manufacturers in order to maintain the speaker, especially for fear of damage to the diaphragm of the TG149 speaker caused by external impact, they will add a maintenance plate on the outside of the diaphragm.
Listen to see if the treble sound is stable. Choose a song with more high pitches to play. When you hear high pitches, you need to pay attention to bringing your ears close to the China TG149 speaker to hear if there is any noise. If there is a lot of noise, it means that the diaphragm of the speaker is unstable and the sound transmission effect is not good. On the contrary, a China TG149 bluetooth speaker with stable treble performance and no noise is worth buying.
