A micro speaker for converting an electrical signal into an acoustic signal, the micro speaker comprising:
- a high-pitched sound speaker unit disposed in an outer case;
- and
- a low-pitched sound speaker unit disposed in the outer case together with the high-pitched sound speaker unit,
- wherein the high-pitched sound speaker unit and the low-pitched sound speaker unit are disposed in the outer case so that a high-pitched sound vibrating plate of the high-pitched sound speaker unit and a low-pitched sound vibrating plate of the low-pitched sound speaker unit have directions opposite to each other,
- wherein a high-pitched sound frame of the high-pitched sound speaker unit is provided with a high-pitched sound rear opening opened toward a rear of the high-pitched sound vibrating plate, and a low-pitched sound frame of the low-pitched sound speaker unit is provided with a front opening and an auxiliary opening opened toward a front of the low-pitched sound vibrating plate, and
- wherein the high-pitched sound speaker unit has a size smaller than that of the low-pitched sound speaker unit and the high-pitched sound rear opening is disposed on a straight line with the auxiliary opening.
A micro speaker for converting an electrical signal into an acoustic signal, the micro speaker comprising:
- a high-pitched sound speaker unit disposed in an outer case;
- and
- a low-pitched sound speaker unit disposed in the outer case together with the high-pitched sound speaker unit,
- wherein the high-pitched sound speaker unit includes a high-pitched sound frame having an inner space opened so as to direct toward an eardrum of a user, a high-pitched sound magnet attached to the inner space of the high-pitched sound frame, a high-pitched sound vibrating plate disposed at a front of the high-pitched sound magnet, and a high-pitched sound voice coil vibrating the high-pitched sound vibrating plate as vibrating in cooperation with the high-pitched sound magnet,
- the low-pitched sound speaker unit includes a low-pitched sound frame having an inner space opened so as to direct toward a side opposite to the eardrum of the user, a low-pitched sound magnet attached to the inner space of the low-pitched sound frame, a low-pitched sound vibrating plate disposed at a rear of the low-pitched sound magnet, and a low-pitched sound voice coil vibrating the low-pitched sound vibrating plate as vibrating in cooperation with the low-pitched sound magnet, and
- the high-pitched sound speaker unit and the low-pitched sound speaker unit are disposed in the outer case so that the high-pitched sound vibrating plate and the low-pitched sound vibrating plate have directions opposite to each other.
