Abstract
The present invention provides a microspeaker having a water drainage structure capable of rapidly discharging water, entering the microspeaker, to the outside. In the case of a woofer-tweeter speaker, water is discharged through the side and bottom of a housing, and in the case of a 1-way speaker, water is discharged through the side of a housing. In addition, the present invention provides a connection portion that is formed to position a plurality of soldering points, to which a woofer wire and a tweeter wire are bonded, not outside a driver but inside or at the boundary of a space formed by the driver in a TWS-type 2-way microspeaker. This secures design freedom and save space by reducing the overall length of a small speaker.
