Abstract

The application discloses a low-frequency radiator which includes two low-frequency radiator bodies, each of which includes elastic pieces and an emphasizer. The low-frequency radiator also includes a framework. The two low-frequency radiator bodies are symmetrically arranged on the framework and define a closed first cavity. Air is arranged in the first cavity. The invention also discloses a sound box. Because the two low-frequency radiator bodies are symmetrically arranged on the framework and define the closed first cavity, and air is arranged in the first cavity, the air in the first cavity is used for supporting so that the two low-frequency radiator bodies arranged at the two sides of the framework generate a damping balance effect and thus phenomena of aftershock, interruption and imbalance and the like are improved in a work process of the low-frequency radiator and at the same time, a low-frequency resonance phenomenon is also generated and natural demonstration of low-frequency parts is facilitated. Through the low-frequency radiator and the sound box, low-frequency sounds, the frequencies of which are from 20HZ to 100HZ, are more stable.

Description

technical field [0001] The application relates to a sound box, in particular to a low-frequency radiator and a sound box. Background technique [0002] Existing speakers include a box with a speaker and a low-frequency radiator. The low-frequency radiator will move synchronously due to the sound from the speaker. Under the impact of the airflow generated by the sound of different frequencies, the low-frequency radiator will bounce back and forth. , and return to its original position under the action of the elastic force. Existing low-frequency radiators may produce aftershocks, discontinuities and imbalances during operation. Contents of the invention [0003] The application provides a low-frequency radiator and a sound box. [0004] According to the first aspect of the application, the application provides a low-frequency radiator, including a low-frequency radiator body, the low-frequency radiator body includes an elastic member and a weight provided on the elastic m...
