A portable speaker is an audio system that you can carry with you. It can operate from both mains and battery power sources. Modern modules allow playing audio material from external media such as flash cards, disks, and SD cards. To achieve high sound quality, multiple audio output bands can be used, each responsible for a specific frequency. Today, there are single-way, two-way, and three-way models. Single-way models reproduce music through one universal speaker, while two-way and three-way models separate high, low, and moderate frequencies, resulting in increased sound purity. A wide frequency band enables natural sound reproduction. Even when playing high-quality media, a narrow frequency range can degrade the audio experience. Typically, frequency band values range from 10 to 55 thousand Hz. It's known that turning off speakers without playing audio can produce background noise from the amplifier. While it's impossible to completely eliminate this noise, high-quality devices minimize noise levels, typically ranging from 45 to 100 dB. Nowadays, most users store information on their own media such as memory cards and mobile devices. It's crucial that the speaker has enough ports to connect to such equipment. Modern models can work with Android smartphones, Apple devices, as well as all popular types of memory cards. Additionally, advanced devices can connect wirelessly. It's important that the speaker doesn't produce noise in response to additional waves, such as when a phone rings or a nearby radio plays.
