The utility model belongs to electroacoustic transducer technical field discloses a moving coil type sound head and microphone. The moving coil type sound head includes shell, first sound pickup subassembly and second sound pickup subassembly, the inside of shell has acoustic cavity, shell has the sound inlet, acoustic cavity is connected with outside through sound inlet, first sound pickup subassembly includes first magnet and first sound film, is provided with first coil on first sound film, first sound film is opposite sound inlet and is arranged in acoustic cavity, first magnet is arranged in acoustic cavity, first sound film vibration drives first coil to move relatively first magnet and produces electric current, second sound pickup subassembly includes second magnet and second sound film, second magnet is arranged in acoustic cavity, second sound film and first sound film are along the propagation direction of sound wave in acoustic cavity and are spaced, are provided with second coil on second sound film, second sound film vibration drives second coil to move relatively first magnet and produces electric current. The moving coil type sound head improves the sensitivity of sound signal acquisition, can better capture and restore sound signal.

The application provides a battery box carrying device, belonging to the technical field of workpiece carrying; the battery box carrying device is installed on an injection molding mechanism, and comprises a cross beam, a moving plate, a connecting beam, a first roller, a first lifting mechanism, a stand, a turnover mechanism, a mounting plate, a displacement mechanism, a carrying mechanism, a workbench, a second lifting mechanism, a lifting plate and a pushing mechanism; the second lifting mechanism drives the lifting plate to move upward to shorten the distance between the lifting plate and the mounting plate, thereby shortening the stroke of the downward movement of the first lifting mechanism to reduce the production cost of the product; the displacement mechanism drives the carrying mechanism to move a short distance to accurately control the moving distance of the carrying mechanism, thereby ensuring that the carrying mechanism can pick up the battery box workpiece to avoid inaccurate control of the moving distance of the carrying mechanism, which causes the carrying mechanism to be unable to pick up the battery box workpiece, thereby improving the use experience of the product.

The utility model relates to contact lens automation production technical field, concretely is a kind of contact lens UV light solid equipment, including feeding station, light solid host computer and discharging station, its characterized in that, gas injection and exhaust mechanism is equipped on the light solid host computer, the feeding place and the discharge of light solid host computer are all provided with airtight mechanism, the curing conveying line that does not protrude light solid host computer is provided in the light solid host computer;The starting end of the curing conveying line is located at the feeding place of light solid host computer, and the termination of curing conveying line is located at the discharge of light solid host computer;The present contact lens UV light solid equipment improves the stability of light solid host computer internal environment, reduces oxygen content, reduces oxygen inhibition effect, reduces the influence of high temperature on curing operation, improves curing quality;Realize the light solid operation of automation, reduce the proportion of manual operation, improve curing efficiency, reduce artificial cost and the quality fluctuation caused by factor, ensure the quality high consistency of contact lens product.
