Problems solved by technology

[0003] The disadvantage of conventional linear resonant drives is that effective vibration can only be generated by using the resonant frequency determined by the weight body and the elastic member for the purpose of transmitting simple vibrations
[0004] Through the traditional tactile providing device, it can only provide vibration in a specific resonance frequency band, but it is difficult to achieve vibration in the ultra-low frequency band (below 20Hz) or the high frequency band above 1KHz

Embodiment Construction

[0044] Embodiments of the present invention will be described in detail below with reference to the drawings. It should be noted that when assigning numbers to constituent elements in each drawing, the same reference signs are used as much as possible even if the same constituent elements are shown in different drawings. Also, in describing the embodiments, when it is judged that the detailed description of the corresponding well-known constitution or function hinders the understanding of the present invention, the detailed description thereof is omitted.

[0045] In addition, terms such as first, second, A, B, (a), and (b) can be used in describing the constituent elements of the embodiment. The above-mentioned terms are only used to distinguish this constituent element from other constituent elements, and do not limit the nature or order of the corresponding constituent elements through the terms. When it is stated that a constituent element is "connected", "combined", or "...

Abstract

A broadband driver according to an embodiment may include: a cylindrical housing having an inner space; and a yoke member disposed in the inner space and having a cylindrical inner portion protruding upward from a center of a lower side of the inner space a yoke; a hollow radial magnet arranged to wrap around the outer peripheral surface of the inner yoke; a moving body having a cylindrical mass body arranged to wrap around the outer peripheral surface of the radial magnet and along the mass a coil portion provided on the periphery of the body; and an elastic member that elastically supports the moving body from one side of the inner space.

Description

technical field [0001] The invention relates to a broadband driver. Background technique [0002] As a general tactile sensation providing device, a linear resonance driver is mainly used, which is driven in such a way that the vibration intensity is maximized using a resonance frequency generated by an elastic spring and a weight body connected to a magnetic circuit. [0003] A disadvantage of conventional linear resonance drives is that effective vibrations can only be generated using the resonance frequency determined by the weight and the elastic member for the purpose of transmitting simple vibrations. [0004] Traditional tactile devices can only provide vibration in a specific resonant frequency band, but it is difficult to achieve vibration in an ultra-low frequency band (below 20 Hz) or a high frequency band above 1KHz. [0005] Therefore, there is a need to develop a tactile sensation providing device that can provide various tactile sensations through vibration i...
