Abstract: The present invention relates to a MEMS microphone package which improves a sound characteristic by forming an additional chamber with a photo solder resist (PSR) dam on a PCB to expand a back chamber. The MEMS microphone package of the present invention comprises: a MEMS microphone chip; the PCB on which the additional chamber is formed with the PSR dam of a predetermined height at a position in which the MEMS microphone chip is mounted; and a case which is coupled with the PCB to form a space in which the components are stored, and is characterized in that a back chamber space of the MEMS microphone chip is expanded by the additional chamber. The additional chamber is manufactured by hardening PSR ink after forming a shape of a rectangular ring with the PSR ink for preventing the attachment of solder on an unnecessary part in a PCB manufacturing process and protecting surface circuits from the external environment. The present invention can improve sensitivity and can improve noise such as total harmonic distortion (THD) and the like by forming the additional chamber with the PSR dam and attaching the MEMS microphone chip thereon to increase the insufficient back chamber space of the MEMS chip.

Abstract: The present invention relates to a roller blind having a safety string, the bottom of which raises and lowers a blind fabric separate therefrom, wherein the length of the string is shortened such that string is in a position that is sufficiently high so as to be out of the reach of the hands of children. The use of the roller blind according to the present invention enables excellent effects to be obtained by completely avoiding the possibility of an accident occurring, such as the blind-pulling string becoming wrapped around the neck of a child.

Abstract: The present invention relates to a spacer-integrated diaphragm, in which spacers are integrated with the diaphragm, in order to reduce the number of components and manufacturing processes needed and remove parasitic capacitance. A characterizing feature of the spacer-integrated diaphragm of the present invention is that it has an integrated structure comprising a diaphragm of a flat conductive film, and thermally insulative spacers formed so as to protrude on peripheral portions of the diaphragm through a PSR (Photo Solder Resist) printing process. The spacers are formed with a plurality of holes to remove parasitic capacitance, the diaphragm has a rectangular flat shape with round edges, and the spacers are formed near the four edges of the rectangular flat shape. In the spacer-integrated diaphragm of the present invention, because the spacers are formed of a PSR (Photo Solder Resist) material and are also formed with a plurality of holes, the present invention can prevent unnecessary parasitic capacitance from occurring and improve sound quality, and, because the diaphragm and the spacers are integrally formed, the present invention can reduce the number of processes needed when a condenser microphone is assembled and reduce the number of components required, thereby reducing manufacturing costs.
