The invention discloses a quickly-lifting robot body. An adjusting shaft is vertically arranged; the top end of the adjusting shaft is fixedly connected with an adjusting handle which can drive the adjusting shaft to rotate while the bottom end of the adjusting shaft is connected with one end of a plurality of adjusting arms; the plurality of adjusting arms are uniformly arranged around an axial direction of the adjusting shaft and the other ends of the adjusting arms extend toward the inner wall of an annular adjusting cylinder and the adjusting warms and the inner wall of the annular adjusting cylinder are fixedly connected; the diameter of the annular adjusting cylinder is smaller than that of the body; a circle of hollow plates are formed on the same planar position of the wall of the body and the annular adjusting cylinder along a circumferential direction, and a plurality of through holes are uniformly formed in the hollow plates; a loudspeaker is mounted on the outer wall of the annular adjusting cylinder and is placed on the inner sides of the hollow plates; a hollow chamber for accommodating a lifting mechanism is formed between the inner bottom wall of a body sleeve and the body; and a controller for controlling the lifting of the lifting mechanism is arranged on the outer wall of the body sleeve. The direction of the loudspeaker can be flexibly adjusted at 360 degrees according to the requirement, and meanwhile, the sound production height of the loudspeaker can be adjusted according to the requirement.

The invention discloses an earphone charging box and a voice playing system thereof, and relates to the technical field of earphones. The voice playing system comprises a voice triggering module, a voice integrated circuit module, a loudspeaker module and a control unit module, wherein the input end of the control unit module is connected with the voice trigger module, the output end of the control unit module is connected with the voice integrated circuit module, and the control unit module is used for acquiring preset target voice information according to a trigger signal generated by the voice trigger module and transmitting a target voice signal corresponding to the target voice information to the voice integrated circuit module; and the output end of the voice integrated circuit module is connected with the loudspeaker module and is used for sending a corresponding voice analog signal to the loudspeaker module according to the target voice signal so as to trigger the loudspeaker module to perform voice playing according to the voice analog signal. A sound production function of the earphone charging box is realized so that the playability of the earphone charging box is improved, and use stickiness of a user is enhanced.

The invention relates to wearing equipment used after operation of pharyngolaryngeal cancer. The wearing equipment comprises a dust prevention cover and an electronic larynx sound production device, wherein the dust prevention cover comprises a cover-shaped casing; the casing is provided with densely-distributed air holes; filter cotton is arranged on the inner side of the casing; the edge parts on the two sides of the casing are connected with the two ends of a bandage; the electronic larynx sound production device comprises a power supply, a vibrating sensor, an A / D conversion module, a PWMgeneration module and a sound production board, arranged in a housing; the vibrating sensor, the A / D conversion module, the PWM generation module and the sound production board are sequentially electrically connected and are connected with the power supply; the housing takes the shape of a ring; the casing is positioned at the center of the housing and is connected with the housing; and the housing is provided with a sound production hole. The dust prevention cover and the electronic larynx sound production device are integrated, the electronic larynx sound production device is always stuck tothe neck part of a patient, an electronic larynx does not need to be lifted up when the patient needs to speak, and therefore, the wearing equipment is convenient to use.

The invention relates to a doorbell, in particular to an integrated intelligent anti-theft doorbell. The integrated intelligent anti-theft doorbell comprises a doorbell main body, a plastic outer shell, a power supply system, a single chip microcomputer system, at least one of a vibration sensor and a sound sensor, a swing switch and a sound production system, wherein the power supply system is connected with a power supply port of the single chip microcomputer system; the at least one of the vibration sensor and the sound sensor is connected with at least one signal input end of the single chip microcomputer system; the swing switch is connected with another signal input end of the single chip microcomputer system; and the sound production system is connected with a signal output end of the single chip microcomputer system. By adopting the design, the vibration sensor or the sound sensor can acquire a vibration signal or a sound signal and transmits the signal to the single chip microcomputer system, thus the single chip microcomputer system has a data basis for judging door knocking sounds accurately, thereby carrying out accurate judgment. The integrated intelligent anti-theft doorbell allows the sound production system to start to send out doorbell prompting sounds when judging that door knocking sounds exist.
