Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-4, a loudspeaker for increasing volume effect comprises a housing 2, a horn 12 is arranged on one side of the outer surface of the housing 2, an extension side plate 5 is arranged inside the horn 12, an operation ring 6 is arranged on one side of the outer surface of the extension side plate 5, an anti-drop block 13 is arranged on the other side of the outer surface of the extension side plate 5, a sound head 7 is arranged inside the housing 2, a buffer mechanism 11 is arranged on one side of the sound head 7, a spring 8 is arranged on the inner surface of the buffer mechanism 11, a limiting rubber 10 is arranged on one side of the spring 8, a magnet 1 is arranged at the upper end of the buffer mechanism 11, a vibrating membrane 3 is arranged on one side of the magnet 1, a protection mechanism 4 is arranged on one side of the vibrating membrane 3, a fixed rotary drum 14 is arranged on the outer surface of one end of the protection mechanism 4, a movable rotary drum 15 is, the outer surface of the lower end of the shell 2 is provided with a handle 9.

A movable groove is formed between the extension side plate 5 and the horn 12, the outer surface of the extension side plate 5 is movably connected with the inner surface of the horn 12 through the movable groove, and the number of the extension side plates 5 is a plurality of groups, so that the effect of the horn 12 is favorably improved; the outer surface of one end of the protection mechanism 4 is movably connected with the inner surface of the movable rotary drum 15 through the dismounting threaded column 16, so that the maintenance of the vibrating membrane 3 in a good follow-up state is facilitated; the outer surface of the magnet 1 is movably connected with the inner surface of the buffer mechanism 11 through the spring 8, and the number of the spring 8 and the number of the limiting rubber 10 are a plurality of groups, so that the whole damping capacity is improved, and the magnet 1 is protected better; a sound channel is arranged in the shell 2, so that the sound is more concentrated; the outer wall of the handle 9 is provided with anti-slip threads, which is beneficial to more convenient grasping.

It should be noted that, the utility model relates to a loudspeaker for increasing volume effect, when using, we can grasp the handle 9 with hand to take up the loudspeaker, then the mouth aims at the rear end of the loudspeaker, the sound is conducted to the vibrating diaphragm 3 through the sound head 7, the magnetic force of the magnet 1 is cooperated to make the sound spread along the internal sound channel, and then the amplification is realized through the power amplification of the horn 12, thereby achieving the effect of sound amplification, in the actual using process, because the horn 12 style of the traditional loudspeaker is fixed and can not be adjusted, so when needing to further increase the volume, the satisfaction can not be reached, aiming at the problem, the problem can be improved by extending the side plate 5, when in concrete operation, the operation ring 6 is pinched with hand and then the extending side plate 5 is pulled out from the inside of the horn 12, thus the enclosure formed by the horn 12 can be made bigger, thereby further increasing the volume, and there is restriction of the anti-drop block 13 while pulling out the extension side plate 5, so does not worry about being pulled out directly, have reached better result of use, the use of the whole loudspeaker is mainly realized by the vibration of the diaphragm 3, but the traditional loudspeaker lacks certain protective measures to the diaphragm 3, so cause will cause some damage to the diaphragm 3 if influenced by external force while using, this problem can be improved by the protective mechanism 4, when the protective mechanism 4 isolates the diaphragm 3 from other mechanisms inside, can promote the protective capacity of the diaphragm 3, and can separate the protective mechanism 4 from movable tumbler 15 through disassembling and assembling the threaded post 16 later stage, so can carry on the normal maintenance or detection to the diaphragm 3, the result will make the life of the whole loudspeaker promote further, there is a more fragile mechanism besides diaphragm 3 in the loudspeaker just magnet 1, can go on through buffer gear 11 in order to promote the protective capacities to magnet 1, when the external force collision that the megaphone received passes and leads to inside, can be cushioned most dynamics by spring 8, just make the dynamics act on magnet 1 surface at last, just so can be maximum the rainproof ability of promotion magnet 1, and spacing rubber 10 can carry out last protection when the dynamics reaches certain degree, avoid magnet 1 because the striking is not hard up and cause direct collision with megaphone inner structure, thereby the effectual result of use that promotes the megaphone, whole easy operation is swift, and is practical.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
