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.

Abstract: Disclosed herein is a 2-way type microspeaker having a drum safety filter (DSF) structure. The 2-way type microspeaker includes a woofer diaphragm, a first coil positioned between a central portion and boundary of the woofer diaphragm, a main magnet disposed inside the first coil, a sub-magnet installed outside the first coil, and a tweeter diaphragm disposed to face the woofer diaphragm. The microspeaker further includes a side support configured to support and surround the sub-magnet, and a first split support configured such that the upper portion thereof supports the rim of the woofer diaphragm and the lower portion thereof comes into contact with the top surface of the side support and also configured such that an open window of a predetermined size is formed such that high-pressure air can flow out.

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 a grill-integrated low-pass filter. The grill-integrated low-pass filter includes a conduit-type low-pass filter part in which a sound conduit is formed inside an internal space of a grill, which is a mechanism assembled and used in a housing, in an empty tubular form, and the conduit-type low-pass filter part is integrated with the grill. According to the present invention, there are provided the grill-integrated low-pass filter that is designed in a structure in which the sound conduit is formed inside the internal space of the grill disposed and used in a housing in order to protect a speaker driver, etc. and is thus fabricated in a grill-integrated form, thereby achieving the effects of improving the sound quality of the speaker and reducing characteristic deviations in a low-frequency band.

Abstract: Disclosed herein is an earphone having a nozzle-integrated structure with a DSF applied thereto. The earphone includes: a housing formed as a penetrated body, and configured such that a nozzle portion is provided therein; a retainer configured to be fastened inside the housing; a magnet configured to generate magnetic force; a yoke configured to concentrate magnetic force; a plate configured to collect magnetic force; a voice coil configured to generate a magnetic field and vibrate through the interaction with the magnet; and a diaphragm configured to vibrate and generate sound. A penetrated sleeve is provided inside the housing and forms a nozzle portion. A drum safety filter (DSF) hole is formed in one side of the edge of a seating surface and a mesh member is disposed below a portion of the retainer in which the DSF hole is formed.

Abstract: A rectangular microspeaker according to the present invention transfers vibration sound through the front surface or side surface of a diaphragm. In order to maximize an effective vibration area and to expand a volume, all parts including a frame are fabricated in a rectangular shape. The present invention is applied to a P type, an F type, and a composite type. The vibration sound generated on the bottom of the diaphragm as well as the vibration sound generated on the top of the diaphragm may be discharged through the side surface. A magnetic field part may be insert-molded separately or along with the frame.
