Abstract

The invention is applicable to the technical field of sound boxes, and provides a passive radiator, comprising a vibrating plate and an elastically deformable framework. The framework is provided with a side wall, a top wall and a bottom plate; the side wall gradually inclines upward from one end of the framework to the other end, and the side wall is equipped with a lower part on one end of the framework and is equipped with a higher part on the other end of the framework. The vibrating plate is fixedly connected with the top wall, moreover, one end of the vibrating plate is a connecting end, and the connecting end is rotatably installed on the lower part of the side wall or the bottom plate through a connecting component. The passive radiator of the invention is installed in some electronic products with specific shapes, the lower end of the passive radiator can be arranged in a narrower space, and the higher end of the passive radiator can be arranged in a wider space. Therefore, compared with the traditional passive radiator, the passive radiator of the invention reasonably utilizes the narrow spaces in the electronic products, thereby avoiding the space waste and being conducive to the miniaturization development of the electronic products.

Description

technical field [0001] The invention belongs to the technical field of sound boxes, in particular to a sound box and a passive radiator thereof. Background technique [0002] Passive radiators are also called passive radiators. Speakers using passive radiators usually contain an active speaker unit and a passive unit (passive radiator). Passive drivers are usually similar in shape to active speaker drivers, but without the voice coil and drive magnet. Passive radiators are not connected to any voice coils or circuitry, and are often used to adjust the bass, allowing the designer to adjust the overall tone of the speaker. The movement of the diaphragm in the passive radiator is carried out by the active unit in the speaker to push the air in the box. Through the adjustment of different counterweights, the passive radiator can resonate at different frequencies. [0003] The middle of the passive radiator is a vibrating plate, and the surrounding diaphragm is made of rubber e...
