Heart position is fixedly installed with one layer of protective net, and the two sides of the panel are movably set with a limit clamp respectively up and down, described
The upper end of loudspeaker shell is fixedly installed with one of mobile rack, and the upper end of the mobile rack passes through the gear teeth and a No.1 driving cog
Wheel intermeshing, the same gear teeth excessively in the upper end of the No.1 transmission gear and No. two transmission gear are intermeshed, and described two
The side of number transmission gear, which is separately connected with outside one, adjusts ring, and the rear end sides of the loudspeaker shell are respectively equipped with a sound-muffling box,
The Internal back end of the loudspeaker shell is equipped with an outer sound loudspeaker, and the bottom of the outer sound loudspeaker is fixedly installed to peace by mounting rack
The bottom behaveing affectedly.
Preferably, the width of the panel is equal to three times of loudspeaker shell tail width, and the both sides of the head of loudspeaker shell is logical
Curved surface is crossed to seamlessly transit to wide with panel, the height of the panel be equal to the height of loudspeaker shell and the height of mobile rack it
With.
Preferably, the two sides side upper and lower position of the panel offers a flexible card slot respectively inwards, described flexible
Card slot is internally provided with a limit spring, and one end of the limit spring is fixedly mounted on the bottom of flexible card slot, described
As soon as the other end of limit spring is then connected with a piece postive stop baffle, the limit clamp is fixedly mounted on the another side of postive stop baffle
On, the postive stop baffle is located at the inside of flexible card slot, and limits clamp then protruding flexible card slot, and snap onto installation cavity
On the inner wall of two sides in the corresponding limit card slot opened up.
Preferably, the mobile rack is fixedly mounted on the upper end of loudspeaker shell, the No.1 driving cog by welding manner
Wheel is located at the surface of mobile rack, and No.1 transmission gear is movably arranged on peace by a No.1 installation axle in the center point
On the inner wall behaveing affectedly, No. two transmission gears are then located at the surface of No.1 transmission gear, and No. two transmission gears are same
On the inner wall that the center point is movably arranged on installation cavity by No. two installation axles, the side of No. two transmission gears is fixed
It is coaxially connected with outside one and adjusts ring, the outer edge for adjusting ring passes through the regulating tank on interior shell body surface, and is exposed at interior
Adorn the outside of shell.
Preferably, the outer sound loudspeaker is mainly by T iron, magnet, Hua Si, voice coil, bullet wave, frame, cone and dustproof cover group
At the magnet is covered in T iron and this can be compressed by China, and the head of the voice coil is fixedly connected with wave is played, and voice coil

The bottom surface of frame 20, cone 21 and dustproof cover 22 are all mounted on the inside of frame 20；What sound-muffling box 28 and loudspeaker shell 1 were integrally formed
Component, the inner hollow of sound-muffling box 28, and it is filled with silencing cotton 29.
It should be noted that the present invention is a kind of general-purpose aircraft loudspeaker with sound amplification function, by outer sound loudspeaker
6 exterior design installs a loudspeaker shell 1, and the wide tail portion in the head of loudspeaker shell 1 is narrow, can play good poly- sound and amplify effect
Fruit, and it is arranged one one by the way that a mobile rack 5 is fixedly mounted in the upper end of loudspeaker shell 1, while in the upper end of mobile rack 5
Number transmission gear 8 and mobile rack 5 are intermeshed, and are equally passed through the gear teeth in the upper end of No.1 transmission gear 8 and are passed with one No. two
Moving gear 10 is intermeshed, and is connected in the side of No. two transmission gears 10 and is adjusted ring 12 outside one, and the outer edge for adjusting ring 12 is logical
It crosses the regulating tank 13 that 14 surface of interior shell body opens up to stretch out, people is facilitated to be rotated with hand；In actual use, it is first depending on left hand
Law, when being broadcasted, sound is converted to electric signal before this, the diatom of belt current it is vertical with the magnetic line of force put magnet south into
Between the arctic, conducting wire will by the magnetic line of force and both electric currents interaction and move, then a piece of vibrating diaphragm is attached to this root diatom
On, as curent change vibrating diaphragm just generates the movement of front and back, so that sound sending is converted electrical signals into, at this point, passenger passes through
Outer adjusting ring 12 is rotated down, so that No. two coaxial transmission gears 10 is driven to rotate clockwise along No. two installation axles 11, and
The No.1 transmission gear 8 engaged with No. two transmission gears 10 is rotated counterclockwise along No.1 installation axle 9 therewith, to drive movement
Rack gear 5 is protruding, i.e., drive loudspeaker shell 1 move out, at this point, the limit clamp 4 of 1 front console of loudspeaker shell, 2 two sides by
The extruding of limit card slot 26 retracts in flexible card slot 23, continues to rotate outer adjusting ring 12, until loudspeaker shell 1 is completely from installation cavity 27
Interior stretching, at this point, the sound-muffling box 28 of 1 tail portion of loudspeaker shell is tightly attached on the inner wall of installation cavity 27, the sound portion that outer sound loudspeaker 6 issues
Divide and is transmitted through sound-muffling box 28 to interior shell body 14 by the shell of 1 tail portion of loudspeaker shell, and during transmitting, sound, which enters, to disappear
In silencing cotton 29 inside sound box 28, via the fine and close pore on 29 surface of silencing cotton and inside, by air molecule friction and glue
Resistance hysteresis, and fiber fines is made to make mechanical oscillation, to enable sound to be changed into thermal energy, to obstruct sound to interior shell body
14 transmitting avoids sound and empathizes in interior shell body 14 phenomenon, and people is caused not hear the sound of loudspeaker sending,
And most sound is after loudspeaker shell 1 amplifies, form the sound beam more concentrated transmits forwards, facilitates people and listens Chhnang
The particular content for the sound that sound device issues, plays good amplifying effect, when without using loudspeaker, need to only be rotated up
Outer adjusting ring 12 retracts loudspeaker shell 1 after the transmitting of No. two transmission gears 10, No.1 transmission gear 8 and mobile rack 5
In installation cavity 27, when the panel 2 of 1 front end of loudspeaker shell is flushed with 14 surface of interior shell body, the limit clamp 4 of 2 two sides of panel exists
It is sticked into limit card slot 26 under the action of limit spring 24 again after extruding, so that loudspeaker shell 1 is fixed in installation cavity 27,
Guarantee in takeoff and landing, slight vibration will not make 1 auto-extending of loudspeaker shell.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
