Problems solved by technology

[0002] An electroacoustic transducer is a device used to receive an electrical signal and convert the electrical signal into an acoustic signal, or receive an acoustic signal and convert the acoustic signal into an electrical signal. When the electroacoustic transducer is dropped or bumped When impacting, the internal transducer device will move relative to each other, and may come into contact with the shell of the transducer, which will have a certain impact on the transducer device. Therefore, it is necessary to protect the transducer device inside the electro-acoustic transducer against impact. Protection, the structure of the anti-shock mechanism inside the existing electro-acoustic transducer is relatively simple, and the buffer movement stroke is relatively large, which may cause irreversible deformation of the related deformation buffer structure, which will affect the effect of anti-shock protection on the transducer device

Abstract

The invention provides an electroacoustic transducer with multiple impact protection, and relates to the technical field of electroacoustic transducers. The electroacoustic transducer with multiple impact protections comprises a second impact protector, a sliding plate is arranged in the second impact protector, a first buffer connecting rod is slidably connected in the sliding plate, a buffer spring is arranged on the surface of the first buffer connecting rod, and a second buffer connecting rod is rotatably connected to the end, away from the sliding plate, of the first buffer connecting rod. According to the electroacoustic transducer with multiple impact protections, an elastic sheet and a transduction assembly are used in cooperation, impact buffering protection can be performed on the transduction assembly, and a first magnetic sheet and a second magnetic sheet are used in cooperation, so that deformation of the elastic sheet can be relieved, irreversible deformation of the elastic sheet can be prevented, and the impact protection effect of the elastic sheet can be guaranteed; a first buffer connecting rod and a second buffer connecting rod are used in cooperation with the buffer spring, secondary impact protection can be carried out on the transduction assembly, and the anti-impact protection effect of the transduction assembly can be effectively improved.
