Abstract
A passive and water-proof loudspeaker sound boosting device includes a loudspeaker, a vibrating diaphragm, a rubber band, a smaller hollow metal bottle body and a bigger hollow metal bottle body, and is characterized in that the smaller hollow metal bottle body has a round bottle mouth; the vibrating diaphragm is tensioned and fixed in the bottle mouth of the smaller hollow metal body through the rubber band, and forms a sealed loudspeaker box with the smaller hollow metal body; the loudspeaker is covered on the vibrating diaphragm of the sealed loudspeaker box in an inverted manner; the bigger hollow metal bottle body is provided with a round bottle mouth, and is covered outside the smaller hollow metal body in an inverted manner. The passive and water-proof loudspeaker sound boosting device has the technical effects that materials are obtained conveniently, the structure is simple, the size is small, the construction cost is low, and the device is portable, and is applicable in occasions without electricity supply and with rainwater spraying.
Description
Technical field
The utility model relates to a kind of loudspeaker sound amplifying device of passive waterproof, particularly a kind of sound amplifying device.
Background technology
The utility model is that the useful of the active sound amplifying device of tradition supplemented.Traditional active sound amplifying device is by power supply, the various voice signals that source of sound is play carry out after power amplification, produce enough large audio-frequency electric diffluence promotion audio amplifier and carry out the amplification of sound, cause it to be not suitable in the use that there is no the occasions such as electric power supply, appearance of the present utility model has solved this problem.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of loudspeaker sound amplifying device of passive waterproof is provided.
The utility model solves the technical scheme that its technical problem adopts: adopt the casing of less pop can bottle as this device, and tightened the vibrating diaphragm that is fixed on less pop can bottle mouth position by rubber band, form closed audio amplifier.In addition, loud speaker is tipped upside down on vibrating diaphragm, by vibrating diaphragm by transmission sound to closed audio amplifier, make less pop can bottle cause resonance, thereby by closed audio amplifier, loudspeaker sound amplified.Finally, larger pop can bottle is tipped upside down on to closed audio amplifier, when reaching the measure of waterproof, again loudspeaker sound is amplified.
The utility model is achieved like this, it comprises loud speaker, vibrating diaphragm, rubber band, compared with areola metal bottle and larger cavity metal bottle, is characterized in that describedly compared with areola metal bottle, its bottleneck is opened round mouth; Described vibrating diaphragm, is tightened the bottle mouth position being fixed on compared with areola metal bottle by rubber band, and with form closed audio amplifier compared with areola metal bottle body; Described loud speaker, is tipped upside down on the vibrating diaphragm of closed audio amplifier; Described larger cavity metal bottle, its bottleneck is opened round mouth, is tipped upside down on compared with areola metal outside bottle.
Technique effect of the present utility model is: adopt the casing of pop can bottle as closed audio amplifier in this device, draw materials conveniently, aboundresources, and the utility model is simple in structure, volume is small and exquisite, cheap, be convenient for carrying, be adapted at not having the use that electric power is supplied with, rainwater waters the occasions such as pouring.
brief description of the drawings.
