Abstract: Press mold for secondary battery a press upper mold; at least two overforming punches arranged to be raised and lowered in the press upper mold; a plurality of forming punches arranged in the press upper mold to be raised and lowered between the overforming punches and the press upper mold; a press lower mold provided with a bridge forming protrusion protruding from an upper surface thereof; the bridge forming protrusion configured to form a bridge to be protruded from the pouch sheet, and a pouch sheet holder disposed to be raised and lowered on the press lower mold and fixing the pouch sheet together with the press upper mold, wherein the plurality of forming punches include a center punch in which a bridge forming groove into which a bridge is inserted is recessed on a lower surface.

Abstract: A thermometer is provided that includes a main body having a first body including first and second regions and a second body mounted on the first body, the main body extending in a first direction; a rubber cap surrounding the second region and formed to be inserted into the ear; a temperature sensor disposed in the second region and having a specific temperature sensing range with respect to the first direction; and first and second circuit boards electrically connected to the temperature sensor and disposed in the second region in a second direction intersecting the first direction.

Abstract: An earphone capable of making it easy to remove foreign substances that have accumulated on a nozzle portion and easy to control sound characteristics thereof is provided. The earphone includes a driver, a housing defining an electrical component mount on which the driver is mounted, a nozzle portion provided at one end of the housing and defining therein a nozzle hole communicating with the electrical component mount, a nozzle cap detachably coupled to an outer circumferential surface of the nozzle portion, and a nozzle mesh provided at the nozzle cap so as to cover the nozzle hole, wherein the nozzle cap serves to decrease output in a second peak region in a graph of output over frequency for the earphone and to increase a fourth peak region or expand a bandwidth of the fourth peak region in the graph.

Abstract: An ear unit and a portable sound device having the same are provided. The ear unit includes a driver unit, an ear housing configured to form an electric part in which the driver unit is mounted and including a bass hole and a flat hole formed in a first surface of the electric part, a rotator including a second surface opposite the first surface and rotatably coupled to the ear housing, and an opening/closing hole provided in the second surface of the rotator to open or close the bass hole or the flat hole according to rotation of the rotator. The flat hole is connected to an inner hole formed in one position inside the first surface so as to form a duct.
