Ever wonder what type of speakers are on our mobile phones? We commonly see speakers as prominent as boxes. The smallest may only be the size of our portable phone box. Looking at the sizes of our mobile phones, I am wondering how these powerful devices are creating sounds. As an ordinary radio can, it can also play radio, music, video, and hear the voice of the caller.
Likewise, our mobile phone also has loudspeaker features. This enables us to hear the sound even if the device is away from our ears.
The Electrodynamic Speaker
The electrodynamic speaker is the standard speaker used for mobile phones. It is a speaker used to convert the electrical oscillation at audio frequencies to mechanical vibrations by the interaction of the magnet field from the permanent magnet to the current in a moving coil connected with a source of electric oscillations.
The Ultra-Thin Piezoelectric Speakers
Out of curiosity, I also found this ultra-thin piezoelectric speaker. Increased demand for thin, high-quality speakers is due to the global increase in the popularity of the slimmest mobile phone. By design, the piezo speakers used in mobile phones are thinner than those used in most other products. Ideally, to get higher sound quality, the stiff piezo-electric structure and lower speakers’ internal friction should be improved.
Speakers are small audio engines typically installed in mobile phones, portable devices, or other devices for communications. For the most part, speakers are used on mobile phones to produce audio alerts such as phone calls and messages, but not as much frequency. The purpose of mobile phones has now changed with this device that doubles as transportable music players. As new speaker applications emerged, manufacturers started equipping their music and video-centric mobile phones with extra powerful speakers or stereo-enhancing speakers.
We also use it on phone calls, so we don’t have to use our hands while talking with others or meeting with others in one room. The use of this system is called talk-and-over speakers (that use of the mobile phone is called a speakerphone, which is not to be confused with a loudspeaker). The method of attaching speakers to mobile phones can vary between different models. For example, instead of using dedicated speakers to produce alerts, some phone manufacturers utilize the earpiece to accomplish the same results.
Cleaning Our Mobile Phone Speakers
To ensure quality sound, it is recommended to clean our phone’s speaker at least once a month. Regular cleaning of our phone’s speaker surface will help keep it clear and prevent the dirt from getting in. The speaker has a magnet, so it is advisable to keep it clean regularly. If we neglect to clean the speaker periodically, the caked-on gunk debris may corrupt the phone’s audio. Even with good equipment, we may experience audio issues while using the phone.
Here are the step-by-step instructions on how to clean our mobile phone speaker using a toothbrush.
● Clean your hands
Before anything else, always make sure that your hands are clean. This will prevent the dirt from transferring to our phones. After washing your hands, pat them dry with a clean towel.
● Make sure to switch off the phone.
Our phone is susceptible, especially the touchscreen. Never clean your phone if it is switched on.
● Use a Toothbrush
Look for a toothbrush with delicate and soft bristles so as not to scratch the phone’s casing. We can use an old toothbrush but make sure to clean and dry it first thoroughly. Kid’s toothbrushes are excellent to use since their bristles are softer.
● Locate the phone’s speaker port and brush it.
We can identify the phone’s speaker port by four or more dotted lines. The speakers’ locations are usually found at the back or the bottom, along with the charger port. We can check our phone’s user guide if we are not sure of our speaker’s location.
Brush the speaker port gently. Slowly brush the port to remove the dirt. Do not scrub roughly since it may damage the phone inside. Note that our phone has sensitive spare parts.
● Shake the dirt off gently
After scrubbing the speaker port, shake the phone gently to allow the dirt to fall off.
- Wipe the phone
Wipe the phone with a damp cloth to ensure no dirt stays on the surface. We can wet the fabric with water and squeeze the cloth properly to ensure no water is dripping from the cloth.
● Let the phone dry
Make sure the phone is thoroughly dry before turning it on. Allow the phone to dry in the air or wipe it with a clean cloth to remove the moisture.
Our phone speakers allow us to hear incoming calls, so we can communicate with the caller. As mobile phones are used as portable devices for playing music, videos, and games, a high-quality speaker is a must. These speakers are so small and very sensitive, so we must properly take care of our phones, primarily where these speakers are located. We must also carry out regular cleaning on the speaker so we can receive good quality sound from our device.
