A lid is provided for covering or sealing a cup by engaging a rim flange of the cup. The lid includes a top portion and an annular side plate which extends downwardly from periphery of the top portion. The plate is formed with a hole. An engagement plate is disposed on the side plate. A bottom edge of the engagement plate is connected to the plate. A top edge of the engagement plate stretches upwardly along the hole, so that the engagement plate is located in the hole. The plates are flexible. As such, the engagement plate can be pressed and bent inwardly when the lid covers a cup. The engagement plate would then engage with the rim flange of the cup so as to enhance engagement of the lid and the cup.

An earphone plug applicable to different system specifications includes a terminal and a switch device. The earphone plug is inserted into an earphone jack of an external electronic device for transmitting signals by a plurality of exposed signal interfaces of the terminal. The switch device combined with the terminal has a first conductor and a second conductor. When the switch device is switched between a first mode and a second mode, the first conductor and the second conductor alternately contact with two of the signal interfaces. Thus, the signal transmission defined by the signal interfaces is changed and the earphone plug is applicable to electronic devices with different system specifications.

A method for making heat-insulated paper containers and the products made by the same. The method includes steps of: (a) mixing and blending polyethylene terephthalate or polypropylene with an adhesive to form a polymer material; (b) heating and extruding the polymer material with an extruder machine to form a film and coating a surface of paper with the film; (c) cooling and laminating the paper with a laminating roller; (d) continuously coating another surface of the paper with a foam material; and then furling the paper after drying; and cutting the paper into a semi-product and then molding into a paper container; (e) heating the foam material with a heating device. The method can enhance the foam uniformity and the production rate, and decrease the defective rate.

An earphone device with a function of sound quality regulation is provided. The earphone includes a housing, a cover, a speaker and a regulating device. The housing has an accommodating space for receiving the speaker and a plurality of regulating holes for connecting the accommodating space to the outside. One end of the regulating device is fixed on the cover. A blocking portion, which is disposed on the other end of the regulating device and extends into the accommodating space, can partially or completely block the regulating holes when the cover is turned, thereby regulating the leakage between the accommodating space and the outside to achieve different output sound quality.

An audio plug and the method of making thereof are disclosed. The audio plug includes a terminal connected to a cord, a first molding formed between the terminal and the cord, a second molding formed on the first molding, a ring disposed on the second molding, and a strain relief collar mounted on the second molding. The method of making the audio plug includes providing a cord to insert through a ring and a strain relief collar, so as to connect a terminal; forming a first molding between the terminal and the cord using an injection molding process; forming a second molding on an external peripheral surface of the first molding using an injection molding process; and fixing the ring and the strain relief collar onto the external peripheral surface of the second molding.

A remote control lock structure. The lock structure includes a receiving box, a locking member, a transmission mechanism, an electric circuit element and a cover. The locking member is placed in the receiving space aligned with a screw hole of a positioning block with a round hole on the receiving box. An axle rod is extended into and out of the round hole, and one end of the axle rod is connected to a main gearing wheel of the transmission mechanism. The main gearing wheel is connected at its lateral sides with the two power transmission wheels, and two power motors are connected with the electric circuit element which provides electric power to activate one of the power motors, thereby one of the two power transmission wheels and the main gearing wheel are driven to rotate. The axle rod further drives the locking rod to rotate to make the latching rod on the front end of the locking rod extend out and retract in between the screw hole and the round hole.
