Abstract
The utility model discloses a sound control blackboard eraser, which comprises a blackboard eraser body and further comprises a power supply device, a sound control device and a sound production device. The power supply device is respectively connected with the sound control device and the sound production device, and the sound control device is connected with the sound production device. The sound control blackboard eraser has the advantages that sound control can enable the blackboard eraser to make a sound as a response, therefore the blackboard eraser can be found conveniently. Simultaneously a solar cell is installed on the blackboard eraser, thereby saving energy and protecting environment.
Description
Technical field
The utility model relates to a kind of blackboard eraser, especially a kind of acoustic control blackboard eraser.
Background technology
Known blackboard eraser is the apparatus of the indispensable blackboard wiping of school classroom, but blackboard eraser is little owing to volume, is easy to leave about everywhere cause and can't find or lose, and delays the process of giving lessons.
Summary of the invention
To the problems referred to above of existing blackboard eraser, the utility model provides a kind of acoustic control blackboard eraser.
The technical scheme that the utility model technical solution problem is adopted is:
A kind of acoustic control blackboard eraser comprises blackboard eraser, wherein, also comprises an electric supply installation, sound-controlled apparatus and a sound-producing device, and said electric supply installation is connected respectively with said sound-producing device with said sound-controlled apparatus, and said sound-controlled apparatus is connected with said sound-producing device.
Above-mentioned acoustic control blackboard eraser wherein, also comprises a switch and a timing means, and said switch is connected with said timing means, and said timing means is controlled said switch folding, and said switch is connected with said electric supply installation.
Above-mentioned acoustic control blackboard eraser, wherein, said electric supply installation is a battery.
Above-mentioned acoustic control blackboard eraser, wherein, said battery is a lithium battery.
Above-mentioned acoustic control blackboard eraser wherein, also comprises a solar panel, and said lithium battery is the rechargeable type lithium battery, and said solar panel is connected with said lithium battery.
The beneficial effect of the utility model is: through acoustic control can be that blackboard eraser is sounded as responding, and comes to find easily blackboard eraser with this, equips the energy-conservation environmental protection again of solar cell simultaneously.
Description of drawings
Fig. 1 is that the circuit of the utility model connects block diagram.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
As shown in Figure 1, the utility model acoustic control blackboard eraser comprises blackboard eraser, wherein, also comprises an electric supply installation, sound-controlled apparatus and a sound-producing device, and electric supply installation is connected respectively with sound-producing device with sound-controlled apparatus, and sound-controlled apparatus is connected with sound-producing device.Sound-controlled apparatus is obtained the sound that the user sends during use, and the sample sound built-in with it compares, and then connects the position that sound-producing device sends sound prompting user blackboard eraser as relatively obtaining definite results.
Above-mentioned acoustic control blackboard eraser wherein, also comprises a switch and a timing means, and switch is connected with timing means, the folding of timing means gauge tap, and switch is connected with electric supply installation., the sound that the user sends according to sound-producing device can turn-off electric supply installation after obtaining blackboard eraser through switch; Make electric supply installation stop to provide electric power; Reached the effect of saving electricity consumption; Switch starts time switch simultaneously when turn-offing electric supply installation, time switch restores electricity electric supply installation closing a switch voluntarily through after the scheduled time; The scheduled time of time switch can be set at the time of a class, and the utility model acoustic control blackboard eraser has automatic entering holding state after a class finishes like this.
Above-mentioned acoustic control blackboard eraser, wherein, electric supply installation is a battery preferred, lithium battery; The lithium battery light weight, capacity is big, does not increase added burden when blackboard eraser is used; Simultaneously can also needn't often change battery, a solar panel can also be set for lithium battery charges repeatedly; Solar panel is connected with lithium battery, and solar panel can also can directly provide electric power for the utility model acoustic control blackboard eraser for lithium cell charging, plays the effect of energy-conserving and environment-protective.
The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
