3C consumer electronics mainly include six categories: mobile phones, tablets, laptops, watches, headphones, and wireless charging devices. Take Apple products as an example, iPhone, iPad, Mac, Watch, AirPods, MagsaFepParts.

There are three main modules in consumer electronics that use magnets, which are acoustic modules, motor modules and magnetic modules.

Neodymium Magnet in 3C Consumer Electronics Products
Acoustics modules, as the name suggests, are vocal units, and popular names are speakers. The performance of the speakers has a great impact on sound quality.

The magnetic field will be generated in the power -on wire. When the AC audio current is through the coil (ie, the audio coil) of the speaker, the corresponding magnetic field is generated in the audio. The force makes the sound rim vibrate in the permanent magnetic field of the speaker’s own, as the audio current is vibrated. The vibration film and sound of the speaker are connected. When the sound coil is vibrated with the horn film, the surrounding air vibrates, and the speaker will sound. As shown below, this is the principle of the speaker.

The requirements of the acoustic modules of different 3C products are different in the face of tin neodymium iron boron magnet

iPhone and other mobile phone products have high frequency and have certain requirements for mobile phones. Therefore On Mac or iPad, on the one hand, the sound quality needs to be considered. On the other hand, its volume is larger than the mobile phone, and there is more space available. Therefore Metropolitania Watch products such as Watch are small in size and users generally need their needs for sound and low requirements for sound quality. Therefore, magnetic steel with low performance (50h) is also small.
