Water drainage structure and coil wire connection structure for 2-way type microspeaker
View Patent ↗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.
1. A 2-way type microspeaker comprising a woofer and a tweeter, wherein a connection portion to which a woofer wire drawn from a woofer voice coil coupled to a woofer diaphragm and a tweeter wire drawn from a tweeter voice coil coupled to a tweeter diaphragm are bonded is disposed on one side of the tweeter diaphragm, and
wherein an installation location of the connection portion is a height identical or adjacent to that of the tweeter diaphragm.
2. The 2-way type microspeaker of claim 1 , wherein the connection portion comprises at least one segment having a soldering portion to which the tweeter wire is bonded, and at least one segment having a soldering portion to which the woofer wire is bonded.
3. The 2-way type microspeaker of claim 1 , wherein the connection portion has a shape forming a circular curved surface.
4. The 2-way type microspeaker of claim 1 ,
wherein the woofer diaphragm is disposed in an upper portion, and the tweeter diaphragm is smaller than the woofer diaphragm and is installed in a lower portion.
5. The 2-way type microspeaker of claim 4 , wherein an appearance of the microspeaker is formed by a metal frame, and the connection portion is soldered to a frame mounted between the tweeter diaphragm and the metal frame.
6. The 2-way type microspeaker of claim 5 , wherein the woofer wire is drawn to the lower portion along the metal frame and an outer side space formed by the frame and is soldered to each segment.
7. The 2-way type microspeaker of claim 6 , wherein the tweeter wire passes through a side of the tweeter diaphragm and is directly soldered to each segment.
