Abstract: A reinforced music box includes a base portion, a two-sided cogwheel, a step type cogwheel, a music generator, a cover portion and a friction set. The two-sided cogwheel is disposed in the base portion and may rotate axially. The cover portion has a main part, a friction part and a supporting part. The main part, friction part and supporting part are integrally formed and either the main part or supporting part has a plurality of engagement holes that can engage with the fixing protrusions of the base portion. The friction set has a friction part and a spirally cogged stick. The spirally cogged stick may engage with the second cogwheel of the two-sided cogwheel at 90 degree. Therefore, the cover portion, which is integrally formed, may provide better protection and the cost in manufacturing and assembly may be reduced.

Abstract: A spring operated record player organ includes a base apparatus, a driving unit, a gear set, a fixed axle unit, a record player, and a rotation speed governor. The record player is able to rotate with the stable restoring force of a manually wound up coil spring so as to play rhythmical music pleasant to the ear. As this apparatus does not require electric power, it is conveniently usable anywhere.

Abstract: A portable ultrasound height measuring apparatus, which comprises a display module and a measuring module. Wherein the display module comprises a LCD, a speaker, a transparent plank and a skidproof pad. The measuring module comprises an ultrasound emitter, an ultrasound receiver, a start button, a set fingerboard, and under the set fingerboard a microprocessor. The apparatus measures height of measured person by emitting an ultrasound signal from the emitter and receiving a reflecting signal by the receiver, then displays value on the LCD. The display module and measuring module are jointly connected together to make the display module able to rotate, open, and close in a set range of angle relative to the measuring module.

Abstract: A spring operated record player organ is set forth, it includes a base apparatus, a driving unit, a gear set, a fixed axle unit, a record player, and a rotation speed governor. By the manipulatively designed component parts in the mechanism. The record player is able to rotate with the stable restoring force of a manually wound up coil spring so as to play rhythmical music pleasant to the ear. As this apparatus does not require electric power, it is conveniently usable anywhere.

Abstract: An inventive structure of the reduction device of the spring driving musical movement comprises a musical movement base, a gear fixed base, a step spur gear, a bilateral gear and a friction unit; wherein the gear fixed base, formed from project plastic material, installs with a locating hole, two parallel concave grooves and a right-side bilateral gear installing groove thereon; and rivets with the musical movement base in a fixed position by the locating hole. After said step spur gear separately parallelizes in said parallel concave groove, said right-side bilateral gear installing groove and a left-side bilateral gear installing groove on the musical movement base were separately installed with a bilateral gear. And said friction unit locates on the musical movement base to make a worm thereon mutually and vertically engages with a left-side gear of the bilateral gear, to become a spring driving musical movement reduction device.

Abstract: A kind of improved structure of spring driving musical movement, which includes a set of musical base, a set of speed reducer and an upper cover principally.

Abstract: A motor driven electronic music box with a motor in a motor base. The shaft end of the motor has a scroll gear to drive the gear train which connects to an output shaft to provide horizontal output. the crown wheel connects to the vertical output power from the gear shaft. One side of the motor base connects to a base, and the base includes a fixing ring with several sound holes. the fixing ring has aa clasp to fix a speaker. On the side of the base are several bosses to support a circuit board. The circuit board connects to the motor, the speaker, a power source, a switch and an LED. The integrated circuit on the circuit board causes the speaker to produce sounds, and the LED to flash according to the melody. The circuit acts on the output shaft and gear shaft at the same time.

Abstract: The present invention is a new design using a mechanical musical structure to serve a flasher switch. It consists of a base, a musical scale device, a triggering device, a driver and a flasher switch. The above-described devices are installed on the base. When the driver drives the triggering device to rotate, the convex points on the metal tubing of the triggering device would rotate and touch the musical scale rods of the musical scale device. Due to intermittent contact between the musical scale rods and the convex points, the device releases music and triggers the switch to serve a flasher.

Abstract: An electric music box powered by wind-up comprises a housing having a rratchetshaft disposed thereof. A wind-up mechanism is enclosed onto the rratchetshaft. A bevel gear is rotated by the rratchetshaft and a transmit group is rotated by the bevel gear. An output shaft and a transmit group is rotated by the bevel gear. An output shaft is connected to the transmit group to generate other movement. A damping shaft is meshed with the transmit group. A wind cap is disposed above the rratchetshaft. A circuit is disposed above the wind cap which is triggered by joint movement of a cam disposed as the top of the rratchetshaft and a controlling plate having a plurality of teeth thereof. The circuit comprises music IC, speaker and a power source. When the music box is triggered to operate, the speaker will announce music. The circuit is connected with LED device to be blinked with music. The output shaft and relevant elements are moved. A cover lid is used to enclose the configuration.

Abstract: Th present invention is related to a modification made on a regular toy tumbler to let the toy tumbler be equipped with a sound generating IC controlled by a plate spring type microswitch. When the toy tumbler stands still, the microswitch is OFF, and no sound is generated. When the toy tumbler is rocking, the microswitch is ON, and the sound generating IC is triggered to provide audio signal through an electronic speaker. Matching with the innovative outer appearance, the toy tumbler is bestowed with a new life.
