Abstract: A clip-on transceiver microphone includes a first body, a second body, and a pivot shaft assembly. The first body has a circuit board therein. The second body has a battery therein. The battery supplies power to the circuit board inside the first body through a power wire. The first body further has a microphone jack for connecting with an external microphone to receive voice. The first body is pivotally connected with the second body by the pivot shaft assembly. After being assembled, two clipping ends of the first body and the second body are tied to each other. Two squeezing ends of the first body and the second body are pushed to open the two clipping ends and then clip on clothes of a user, thereby attaching the clip-on transceiver microphone on the object of the user.

Abstract: The screwless terminal block includes an insulative body, a base, a pressing sheet and a releaser. The insulative body is hollow and formed with two lateral through holes in alignment with each other. The base is received in the insulative body and has two ends corresponding to the two lateral through holes. The pressing sheet is received in the base and engages with the base to form two electrical contacts. The releaser is mounted on the base and provided with two release keys. A top end of the release key is protrudent from the insulative body and a bottom end thereof is provided with a pushing portion abutting against the pressing sheet. When the release key is pressed, the pushing portion will press the pressing sheet to move away from the base and the conductive wire clamped between the pressing sheet and the base will be released.

Abstract: A key type wiring connection switch includes an insulation main body, a plurality of spring elements, retaining terminals, conducting terminals and pressure buttons. In which a plurality of retaining spaces are formed in the interior of the insulation main body, The pressure buttons are positioned above each of the retaining terminals. Moreover, an upper end of each of the pressure buttons protrudes out the insulation main body. When using the present invention, the user presses downward on each of the pressure buttons to cause each of the lower ends of the pressure buttons to move downward and push open the retaining terminals, thereby enabling connecting wires of a host machine to be extended into the conducting terminals through side through holes of the insulation main body. Accordingly, when wiring an electrical appliance, there is no need for hand tools while still enabling wiring to be carried out.

Abstract: An easy-mount in-ceiling speaker mount has multiple fastening units mounted on an in-ceiling speaker. Each fastening unit has a base frame, a torsion spring securely mounted on the base frame, a pivoting member pivotally mounted on the base frame, a slider plate longitudinally movable on the base frame, and a spring holder receiving the torsion spring, pivotally mounted on the base frame and blocked by the pivoting member. When the speaker mount is moved upwardly through a ceiling, a bottom of the ceiling holds a ceiling support formed on the slider plate and the pivoting member is pushed and pivoted. After being unblocked from the pivoting member, the spring holder is pivoted to hold a top of the ceiling in completion of the mounting of the speaker mount. Accordingly, the mounting procedures of the speaker mount can be easily achieved by simply pushing it upwardly through a ceiling.

Abstract: A microphone worn on a pair of eyeglasses includes a microphone body and at least a suspender. The microphone body includes a thin rod, an end of which is a high sensitivity microphone and the other end is a plug; the thin rod is assembled with an electric wire through the plug and a socket. An upper end of the suspender is installed on a temple at a side of the eyeglasses and a lower end is a hook unit. When the microphone body is used, the thin rod is installed on the hook unit to assemble the microphone body with the temple at the side of the eyeglasses; therefore, when the eyeglasses are worn, the microphone body is worn simultaneously. Not contacting with an ear to cause uncomfortableness, the microphone body is worn conveniently and handy, can be applied to frames of various sizes and carried conveniently.
