Background

The sound equipment is composed of a sound source (music playing equipment, pickup equipment, namely a microphone), control equipment (analog or digital sound console), an audio processor (peripheral equipment such as an effector, an equalizer, a pressure limiter, a frequency divider, a signal distributor, a delayer and the like are used in the past, and a digital system controller integrating the functions, a power amplifier (power amplifier) and a sound box are also used at present. The above devices are used by connecting various types of wires and cables in series. For a power amplifier circuit, which is one of the main components of an audio system, one of its fidelity indicators is the frequency response. Almost all power amplifiers have frequency response characteristics that are not perfectly flat, i.e. they do not provide the same amplification to the frequency components of the source signal, and in particular, they have a large attenuation at both the high and low frequencies. To adjust and correct for this imbalance, a multi-band frequency equalizer is provided in the sound system. However, the existing sound equipment is inconvenient to carry and occupies a lot of land due to individual reasons, and meanwhile, the directivity of the sound equipment body is not very strong.
