The direction of propagation of sound wave is parallel on section so that hearer's sense of hearing in the range of 360 degree is consistent, avoids influencing sound quality.
Preferably, the present embodiment reflection frame 20 further includes mounting base 23 and multiple spaced connecting plates 22, Mei Yilian
One end of fishplate bar 22 is connected to mounting base 23, and the other end is connected to reflection 21 peripheries of cone, mounting base 23, connecting plate 22 and anti-
Pencil 21 cooperatively forms sound outlet hole, and mounting base 23 is detachably connected with frame 11 and offers the opening of corresponding connection outlet sound mouth.
When reflection frame 20 is metal material, reflection cone 21 can be bored by plectane punch forming, wherein connecting plate 22 in reflection
It is integrally formed with reflection cone 21 during 21 punch formings, is conducive to produce, improve production efficiency, and connecting plate 22 passes through weldering
The mode for connecing, being clamped or being spirally connected is connected to mounting plate；
When reflection frame 20 is plastic material, reflection 21 injection moldings of cone, wherein mounting plate and connecting plate 22 can be bored in reflection
It is integrally formed with reflection cone 21 in 21 injection moulding process, is conducive to produce, improve production efficiency；
Mounting base 23 and frame 11 are threadedly coupled simultaneously gripper drum paper 12, easy to disassemble；Reflection cone 21 is made by connecting plate 22
For support, reflection cone 21 is fixed on to the relative position of outlet sound mouth, sound mouth is formed between the periphery and frame 11 of reflection cone 21,
Multiple spaced connecting plates 22 separate sound mouth in multiple sound outlet holes along 21 setting of reflection cone, when drum paper 12 is to anti-
When pencil 21 sends out sound wave, the reflective surface sound wave of reflection cone 21 can blaze abroad along 360 degrees omnidirection.
Further, the multiple connecting plates 22 of the present embodiment are in the circumferential uniform intervals setting of reflection cone 21, and sound is to reflect
The mode of formula is spread out of by multiple sound outlet holes, is not interfere with each other between audio, effectively realize sound quality it is more pure, sound Geng is loud and clear,
Acoustic effect is good.
The present embodiment connecting plate 22 includes four, and one end of four connecting plates 22 connects to be formed along the periphery of reflection cone 21
Cross, the other end connect mounting base 23 along the periphery of opening, and effectively reflection cone 21 is bonded in mounting base 23.
The present embodiment mounting base 23 offers mounting hole, and frame 11 offers connecting hole, mounting base 23 by connector with
Mounting hole and connecting hole cooperation are fixedly connected on frame 11.
Mounting base 23 opens up several spaced mounting holes, when mounting base 23 be plectane when, several mounting holes each along
23 periphery of mounting base is arranged, and when mounting base 23 is square plate, several mounting holes may be contained within the corner of mounting base 23；Frame 11
Several spaced connecting holes, a mounting hole and a connecting hole are opened up relative to bolt passes through mounting hole and connecting hole to buckle
Connection or bolt pass through mounting hole and connecting hole to be threadedly coupled, effectively easy to disassemble.
Preferably, 6 millimeters to 8 of the size range of the spacing between the cone 231 of the present embodiment reflection cone 21 and drum paper 12
Millimeter, the reflecting surface that reflection cone 21 is effectively ensured are directed to the reflection efficiency of sound wave, when the distance between cone 231 and drum paper 12 mistake
Closely, the sound wave of loud speaker 100 cannot be completely by the reflective surface of reflection cone 21；When the distance between cone 231 and drum paper 12
Too far, 100 volume of loud speaker expands, and is unfavorable for realizing volume miniaturization.
Further, the cone 231 of the present embodiment reflection cone 21 is located on outlet sound mouth central axes, effectively keeps sound wave uniform
Propagate to surrounding.
Preferably, the periphery of the present embodiment drum paper 12 is formed with ring 121, and ring 121 is contained in reflection frame 20, ring
121 radius is more than the radius of reflection cone 21.
Ring 121 vibrates and generates resonance (sympathetic response) with the air of surrounding and send out sound wave, and sound wave around reflection by boring
Multiple sound outlet holes of 21 settings are propagated outward so that sound wave is propagated with 90 degree to 180 degree direction, expands spread scope, realization sound
Sound is diffused into 360 degree.
Cone is effectively ensured along axial movement, the limit lateral movement of loud speaker 100 to be arranged, while playing blocking paper
The empty effect for daring circulation before and after basin.
In order to increase the stability of bulging paper 12, surface of the present embodiment mounting base 23 towards frame 11 is recessed to be formed with annular
Limiting slot, drum paper 12 are convexly equipped with annular convex platform to 20 direction of reflection frame, and annular convex platform is caught in annular spacing groove.
When limiting slot is sheathed on bulge loop 122, mounting plate and frame 11 will lock bulge loop 122, effectively more firm connection drum
Paper 12 avoids vibration so that periphery splits when the outstanding side of drum paper 12 is used in persistence.
It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every
Under the inventive concept of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or
Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
