It is increasingly common to find in certain mobiles the characteristic that they are resistant to water and/or dust, under different levels of stamina.
In the case of speakers, when exposed to these elements, their membranes could become clogged and therefore, the quality of the sound could be compromised. If you act in time, before the device is damaged, it is possible to recover its original state.
Frequencies for cleaning a clogged speaker
The solution comes through the same speaker. When emitting sound, its membrane vibrates according to the frequencies of the emitted waves.
Within the range of sounds that these small sound boxes support, some frequencies reach a level that, when vibrated, can clear obstacles that could be damaging their sound, after exposure to water or dust.
In addition to the attached video, platforms such as Clean My Speaker offer similar solutions over the web. The access path is at the discretion of whoever needs it, what matters is the sound itself.
If a loudspeaker has been subject to some kind of damage for these reasons for a long time, the damage is likely to be permanent. Anyway, it's worth a try.
Practical reminders to rescue a wet mobile
If the mobile is subjected to a fall into the water, it is worth turning it off immediately, whether resistant or not. Having the last condition, logically, ensures a higher success rate.
Once off, it is important to dry it as completely as possible. Let the water drain out in a favorable position, dry it with a cloth, and remove as many removable pieces as possible to make the drying process more intensive.
It is important to avoid intervening in those parts that are not easily accessible, such as card slots, charging ports, or headphones. Similarly, the use of hair dryers or other external sources of hot air is not recommended.
Once the phone is dry, it is recommended to turn it on and charge it if necessary after waiting a reasonable period of time. In case the speaker has been compromised, the solutions outlined above can be applied only.
