Vibration output apparatus and portable electronic device comprising vibration output apparatus

Abstract

The present invention relates to an apparatus for outputting vibration, and an exemplary embodiment of the present invention may provide an apparatus for outputting vibration, the apparatus including: a magnetic circuit which generates vibration; a yoke which is in contact with an upper surface of the magnetic circuit and has a raised spot with different heights in a height direction in at least one of lateral surfaces of the yoke such that one or more spaces are formed in an upper surface of the yoke; and an elastic body which is in contact with at least a part of the upper surface of the yoke, and vibratorily moves in the one or more spaces.

Description

TECHNICAL FIELD[0001]The present invention relates to an apparatus for outputting vibration, and more particularly, to an apparatus for outputting vibration by using a bone conduction technology, and a portable electronic device including the apparatus for outputting vibration.BACKGROUND ART[0002]Recently, products using a bone conduction technology, which is mounted in a mobile phone to be widely known, have emerged in succession. Various electronic devices, for example, an application product including a speaker or a hearing aid, using the bone conduction technology, have been commercialized. Temuco Japan, which holds the basic patent related to the bone conduction plans to release a product, such as a speaker and a microphone, which is usable even in a vacuum state and without regard to a usage place, such as underwater, and adopts the bone conduction technology.[0003]In general, vibration of air beats eardrums and the vibration is transmitted to the cochlea, so that a sound is r...

AI Technical Summary

Benefits of technology

[0029]The apparatus for outputting vibration according to an exemplary embodiment of the present invention may increase excitation force of the elastic body, and directly transmit vibration to the body and skin.

[0030]The apparatus for outputting vibration according to another exemplary embodiment of the present invention improve a bone conduction rate by transmitting vibration without a loss.

[0031]The apparatus for outputting vibration according to still another exemplary embodiment of the present invention may prevent a bone conduction rate from being decreased and prevent a distortion phenomenon due to vibration reduction by directly transmitting vibration to the body and skin.

Problems solved by technology

The bone conduction technology itself has been established before, but it is difficult to miniaturize a product adopting the bone conduction technology for commercialization.
