Description of the embodiments

The utility model provides a multifunctional sound box microphone, which is further described in detail below in order to make the purposes, technical schemes and effects of the utility model clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 7, the present utility model provides a multifunctional speaker microphone. For convenience of explanation, some azimuth terms will be used herein, and these azimuth terms are described in a state that the multifunctional speaker microphone faces vertically upwards, and in actual use, the multifunctional speaker microphone may be at other angles. The terms "first" and "second" are used herein to designate only similar structures differently, and are not intended to limit the present utility model.

Referring to fig. 1 to 4, a multifunctional speaker microphone includes a mesh 1, a sound head 2, a vibration damping support 3, a speaker 4, a multi-layer mesh enclosure 12, a motherboard (not shown), a battery (not shown), and a handle 8. The sound box 4 comprises a box body, two horns 42 and a passive plate 43, and the box body comprises a front box 411 and a rear box 412; the two horns are arranged on the front box body, the two horns are arranged in a front-back staggered mode, and the passive plate is arranged on the rear box body; the two horns and the passive plate are obliquely arranged downwards; the net head comprises a net cover and a metal woven net 11 arranged in the net cover, and the metal woven net extends upwards to form a net cover 12; the multi-layer mesh enclosure is mounted on the surface of the horn, and the side wall of the mesh enclosure is horizontally provided with a plurality of first arc-shaped holes 120 (which are shown as rectangular holes in a front view, and are actually arc-shaped holes). As shown in fig. 4, the two horns are not perfectly symmetrical, one of them being relatively more forward and the other being relatively rearward. Preferably, the distance of the front-back misalignment of the two horns (i.e., ΔL in FIG. 4) is 1mm or more. The horn is arranged in a staggered mode, so that the coverage range of the horn sound wave pair is enlarged. The above-described main board and battery are not the point of the utility model, and therefore the drawings do not show the specific structure thereof.

Under the view angle of the top view (as shown in fig. 4, the "included angle" refers to the included angle of the central line of the horn), the included angle of the two horns is approximately equal to the included angle between the passive plate and any one horn. When the loudspeaker is used, the passive plate faces the user, and the sound generated by the two loudspeakers can cover a certain angle range in front and at two sides.

Every loudspeaker and passive plate are not vertical setting, but oblique decurrent setting, namely: the centerlines of the horn and passive plate are not horizontal, but are inclined downward (the angle of downward inclination is not limited herein). The arrangement reduces the interference of sound waves emitted by the sound box to the sound head.

In addition, the arc hole that the level was seted up on the screen panel plays the guide effect to the sound wave, has reduced the sound pickup of vertical direction, has reduced the interference of output loudspeaker sound wave to the sound head for the pickup of sound head is cleaner. The metal net is internally provided with a layer of anti-spraying net (which can be sponge, cloth, foam or other materials with air dispersion function, and is not limited in the place), and is used for preventing the microphone from popping sound caused by larger air flow and filtering noise to a certain extent.

Further, as shown in fig. 2 and 3, the vibration reduction bracket is connected with the top of the box body, and the sound head is connected with the top of the vibration reduction bracket; the vibration damping bracket comprises two split bodies 3, each split body comprises an inner ring 31 and an outer ring 32, and each outer ring is connected with the inner ring through a plurality of vibration damping ribs 33.

During actual assembly, the outer ring is clamped in a fixing groove (not shown in the figure) of the sound box, and traction force is formed between the inner ring and the outer ring to provide good stability for the sound head, so that noise or impact sound generated by shaking in the use process is solved. Through setting up the damping support, form the flexonics between sound head and the audio amplifier, the conduction feedback of sound wave to the sound head when effectively keeping apart the audio amplifier loudspeaker sound production, the interference is reduced.

Further, as shown in fig. 6, an inner mesh 51, an air-permeable mesh 52 and an outer mesh 53 are sequentially disposed outside each horn. The inner net is provided with a plurality of rectangular holes and round holes, and the outer net is provided with a plurality of second arc holes 530 horizontally. And as the sound head shell is the same, the second arc-shaped holes formed in the outer net reduce the feedback interference of sound waves to the sound head, so that the sound is cleaner and more real.

Further, as shown in fig. 5, two sides of the rear case 412 are respectively provided with a diversion trench 400. Through setting up the guiding gutter, the sound that lets the passive board send can the guiding gutter be followed loudspeaker side output, forms synchronous stack with the sound wave of loudspeaker, lets the sound expression more have concentrated sense.

Further, a main board (not shown) and an operation panel 6 are sequentially disposed on the outer side of the passive board. When in actual use, the operation panel faces to the user, so that the key operation is convenient.

Further, the handle is connected with the bottom end of the box body, and a battery (not shown in the figure) is arranged in the handle, and is a rechargeable battery and electrically connected with the main board to supply electric energy to the main board, and meanwhile, the main board provides charging and protection for the main board.

Further, as shown in FIG. 7, two annular conductive plates (91 and 93) are provided at the bottom end of the handle, with an insulating space 92 between the two annular conductive plates (i.e., electrodes). The annular conducting strip is arranged for being matched with the charging base, and an elastic conducting contact pin is arranged on the charging base. Because the inner ring and the outer ring are concentrically arranged, the microphone is placed in the charging seat at any angle, and the annular conducting strip can be contacted with the contact pin of the charging seat mountain, so that charging is performed.

As can be seen from the above analysis, compared with the prior art, the multifunctional speaker microphone provided by the utility model has at least the following main technical advances: (1) The screen panel sets up a plurality of arc holes horizontally, plays the guide effect to the sound wave, has reduced the sound pickup of vertical direction, has reduced the interference of output loudspeaker sound wave to the sound head for the pickup of sound head is cleaner. (2) The loudspeaker and the passive plate are obliquely arranged downwards, so that the interference of sound waves emitted by the loudspeaker box to the sound head is reduced. (3) The outer net of loudspeaker also is provided with a plurality of arc holes, has reduced the sound wave that loudspeaker sent and has produced the interference to the sound head, lets the pickup cleaner. (4) The sound head is connected with the box body of the sound box through the vibration reduction support, so that the problem that noise or impact sound is generated due to shaking in the use process is solved. Therefore, through the improvement of the aspects, the pickup of the microphone of the multifunctional sound box is cleaner, and the sound quality is improved.

It will be understood that equivalents and modifications will occur to those skilled in the art based on the present utility model and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present utility model.
