Abstract
A broadband linear vibrator that is small sized and yet capable of generating a greater vibrating force and outputting various broadband vibrations, and a mobile terminal capable of outputting various vibrations and sounds, wherein the broadband linear vibrator includes a case; a spring coupled to the case; an oscillator including a magnet for elastically supporting the spring and a stator formed inside the case for vibrating the oscillator, wherein a frequency band to a maximum use frequency that is detectable as a vibration or a sound source based on a resonant frequency is 1.2 times than a frequency band to a minimum use frequency, such that various feelings of vibrations and sounds can be advantageously provided by the broadband linear vibrator.
Claims8
A broadband linear vibrator, comprising:
- a case;
- a spring coupled to the case;
- an oscillator including a magnet for elastically supporting the spring and a stator formed inside the case for vibrating the oscillator;
- an upper plate formed between the spring and the magnet, wherein the magnet includes an outer magnet disposed at a periphery of the upper plate and an inner magnet that is centrally disposed:
- and
- a bottom plate formed at a bottom end of the magnet,
- wherein a frequency band to a maximum use frequency that is detectable as a vibration or a sound source based on a resonant frequency is 1.2 times greater than a frequency band to a minimum use frequency, and
- wherein at least one of the upper plate and the bottom plate is formed with a magnetic substance.
