Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a audio system. Background Art

[0002] Audio refers specifically to an audio system that is a combination of electrical equipment that produces sound. The development history of audio technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field-effect transistors. The audio we refer to in daily life is a simplified term, which is the abbreviation of the audio system, that is, it refers to a complete set of equipment that can restore and play audio signals.

[0003] With the progress of society, people yearn for a more colorful life. As a form of entertainment that has been passed down for thousands of years, singing and dancing have penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing. The sound system is constantly improving and perfecting with people's needs. It can meet the needs of live sound reinforcement for concerts with tens of thousands of people, or meet the needs of playing musical instruments and singing karaoke at home.

[0004] An important device in the sound system is the speaker, which is generally composed of a speaker unit and a cabinet. The speaker unit is the sound-generating component, and the cabinet is the supplement of the speaker unit to correct the sound. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electron energies are transmitted to the coil, the coil generates a kind of energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electron energy changes at any time, the speaker coil will move forward or backward, so the speaker paper plate will move with it. These actions change the density of the air and produce sound.

[0005] In order to achieve a more three-dimensional auditory effect, music playback needs to include various parts such as treble, mid-bass, and bass. In order to achieve this effect, multiple speakers with different parts are currently combined, which results in more overall components, occupies more space and is inconvenient to carry.

[0006] There are some audio products that combine multiple sound components of different frequencies in a single box. However, during the design and production of this type of audio, due to some omissions in details or unreasonable original design, some problems may occur in the audio, such as: low signal-to-noise ratio, which reduces the listening experience; high shaking rate during vibration, and inability to stay in the same place.
