A speaker is an electro-acoustic transducer which transforms an audio signal into a corresponding sound. Miniature speakers are tiny loudspeakers designed for products with small diameter requirements.
Miniature speakers have a low profile design with small dimensions, and are fitted with either mylar or paper cones. They often require an external drive circuit to operate.
What are miniature speakers used for?
Miniature speakers are common in devices such as radios, televisions, portable audio players, computers, electronic musical instruments and handheld applications. They are beneficial in devices where a high-quality sound is important and also where durability is necessary. These include high duty products like smart home devices, telecom products such as headsets, and warning controls in manufacturing equipment.
Types of miniature speakers
Miniature speakers come in various shapes and sizes, and can be wireless, waterproof, or Bluetooth-equipped. They can also be either portable or cabled. Cabled speakers require connection to a power source to receive sound signals over cable audio waves. Portable speakers use wireless or Bluetooth technology over short distances, receiving audio signals via radio frequency waves to produce sound.
