Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a loudspeaker device and a sound system. Background Art

[0002] The development of audio equipment requires smaller and smaller size, but higher and higher sound quality. Small size and good low frequency, traditional acoustic design can no longer meet the sound requirements, so we have developed new active compression reflection technology audio equipment.

[0003] Traditional audio structures are divided into three types: 1. Closed box, completely sealed structure, slightly poor low frequency. 2. Open box, duct design, low frequency enhancement, there will be airflow sound. 3. Low-frequency reflex box, using passive radiators to reflect low frequency, the principle is the same as the duct, low frequency enhancement, no airflow sound, easy to be affected by the air pressure movement in the box and irregular swing. The active compression reflection technology audio is an active speaker reflecting low frequency, and autonomously compresses the box air pressure, which not only enhances the low frequency, but also does not produce airflow sound, nor does it swing irregularly, the structure is more stable, and the sound is purer. The initial sound, speaker and box design are purely physical, the volume is designed to be how big the box is. In order to increase the low frequency, there will also be designs such as ducts and radiators. With the development of the times, space is saved, and the volume of audio is also getting smaller. The traditional design can no longer meet the high-fidelity standards of compact audio, and DSP needs to be used to make up for it, but the sound of virtual modification will still be slightly less pleasant, so we must have new technology to break through, so active compression reflection technology came into being.

[0004] Therefore, it is urgent to develop a speaker device with large radiated sound wave energy, high efficiency, high sensitivity, and long low-frequency dive extension. Utility Model Content
