Multi-Resonant Linear Motor

Abstract

The present invention relates to a multi-resonant linear motor, which includes a housing; a vibrating part, which includes a first vibrating system, a second vibrating system arranged at intervals, and a first driving part respectively accommodated in the above systems; a fixing part, which is connected to the The casings are connected, and the fixed part includes a second drive part, which is placed between the first vibration system and the second vibration system and is arranged at a distance from the first drive part of the first vibration system and the second vibration system; the vibration guide part, which It includes a guide rod arranged on the vibrating part and a return spring set on the guide rod, one end of the return spring abuts against the housing, and the other end abuts against the vibrating part; the first driving part interacts with the second driving part, thereby The first vibration system is driven to vibrate along the first vibration direction, and the second vibration system is driven to vibrate along the second vibration direction. The multi-resonance linear motor of the invention has the advantages of compact structure, adjustable vibration intensity, convenient processing and manufacturing, low cost and the like.

Description

technical field [0001] The present invention relates to a vibration generating device, and more particularly, to a multi-resonance linear motor. Background technique [0002] With the development of science and technology and the progress of society, electronic products have been widely popularized. In this way, vibration reminder devices have been widely used. In order to make people feel better about vibration reminders, the performance requirements are getting higher and higher. . [0003] In traditional mobile communication mobile phones and smart phones integrated with PDA functions, the three functions of incoming call sound prompt, incoming call vibration prompt and telephone voice output are completed by three independent devices. Among them, the sounder that can only emit simple music or a speaker with a wider frequency response range performs the voice prompt of the incoming call, the micro DC multi-resonant linear motor performs the vibration prompt function, and...

Problems solved by technology

However, when the mass of the communication terminal such as a mobile phone is large, the vibration force provided by this device is obviously insufficient, and the expected effect cannot be achieved.
