Magnet；Microphone mounting box is socketed in swing arm, and microphone is fixed and is nested with microphone mounting box, and permanent magnet is fixed on pendulum
The outer end of arm, electromagnet is arranged on casing and on the swinging track of permanent magnet, can be with permanent magnet adhesive, swing arm set
Fixation is nested with casing, and curved spring is socketed on spring shaft, and curved spring of the spring shaft together with socket thereon is movable
It is nested with and covers interior and fixedly sleeved in rotating shaft in swing arm, the lower end of rotating shaft, which is fixed, is nested with gear, gear and toothed belts
Internal gear engagement, drive gear conveyer belt rotate；The lower end of described curved spring is fixed on the inwall of swing arm set, distortion
The upper end of spring is fixed on swing arm the inner, the inner rotatable top covered installed in swing arm of swing arm.
After such scheme, loudspeaker of the present utility model is arranged on the middle part of casing, and multiple microphones are respectively mounted
Swung in microphone on assembly, microphone swings assembly and is arranged on casing, due to microphone swings assembly can folding, it is easy to take
Band, and multiple microphones formation microphone array, the microphone area being arranged in array expand, and radio reception is more efficient.Below
The utility model is further described with reference to the drawings and specific embodiments.

Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of folding meeting audio amplifier, including casing 1, loudspeaker 2, six
Microphone 3, microphone swing assembly 4, switch 5.
Described loudspeaker 2 is arranged on the middle part of casing 1, and multiple microphones 3 are separately mounted to microphone and swing assembly 4
On, microphone swings assembly 4 and is arranged on casing 1, and switch 5 is arranged on casing 1 and electrical connection microphone is swung on assembly 4
Electromagnet.
Described microphone, which swings assembly 4, includes six groups of swing mechanisms 41, five toothed belts 42.Described oscillating machine
Structure 41 include microphone mounting box 411, swing arm 412, swing arm set 413, gear 414, curved spring 416, spring shaft 417, rotating shaft
418th, permanent magnet 419, electromagnet 420；Described microphone mounting box 411 is socketed in swing arm 412, the fixed cover of microphone 3
Put in microphone mounting box 411, permanent magnet 419 is fixed on the outer end of swing arm 412, electromagnet 420 be arranged on casing 1 and
, can be with the adhesive of permanent magnet 419 on the swinging track of permanent magnet 419, swing arm set 413, which is fixed, to be nested with casing 1, is turned round
Bent spring 416 is socketed on spring shaft 417, and spring shaft 417 is nested with pendulum together with the activity of curved spring 416 of socket thereon
In arm set 413 and fixedly sleeved in rotating shaft 418, the lower end of rotating shaft 418, which is fixed, to be nested with gear 414, gear 414 and gear
The internal gear engagement of conveyer belt 42, drive gear conveyer belt 42 is rotated, and two are socketed in respectively at the two ends of toothed belts 42
Rotating shaft 418, forms linkage；The lower end of described curved spring 416 is fixed on the inwall of swing arm set 413, curved spring 416
Upper end is fixed on the inner of swing arm 412, the inner rotatable top installed in swing arm set 412 of swing arm 412.
Operation principle of the present utility model：
