    Abstract: Disclosed herein is a hybrid acoustic apparatus. The hybrid acoustic apparatus includes: a rectangular microspeaker used as a first acoustic device; and a second acoustic device integrated with the microspeaker. The microspeaker includes a plate configured to constitute a part of a magnetic field part, a magnet configured to be disposed beneath the plate, a diaphragm configured to be disposed on the plate, and a frame configured to accommodate the diaphragm, the plate, and the magnet. A path of vibration sound generated by the diaphragm is formed to be perpendicular to a direction in which the diaphragm vibrates so that the vibration sound is discharged through a side surface of the diaphragm.

    Abstract: Disclosed herein is an acoustic device with improved acoustic performance. The acoustic device includes: a housing that forms the appearance of the acoustic device; a magnet that generates magnetic force; a yoke that includes paramagnetic material that concentrates the magnetic force; a voice coil that vibrates due to the magnetic force when an electric signal having sound information is applied; a diaphragm that comes into close contact with the voice coil and that vibrates and generates sound in response to the vibration of the voice coil; a plate that is located between the diaphragm and the magnet; and a locking ring that is located on the plate and that fastens part of the diaphragm, wherein the sectional surface of the locking ring has a rectangular shape the height of which is greater than the width thereof.

    Abstract: Disclosed herein is an ear tip having a flange made of silicone foam, the ear tip including a central core and a flange surrounding the core. The flange is made of silicone foam, and the core is made of a material harder than the silicone foam. Before the silicone is molded, attachable films or tapes may be attached to the top and bottom surfaces of the mesh, thereby preventing burrs generated during the molding of silicone from adhering to the mesh.

    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.
