Description
Technical field
The utility model is related to sound equipment and its parts technical field, amplify bugle more particularly, to a kind of loud speaker.
Background technology
Sound speaker is a kind of energy transducer electric signal being changed into acoustical signal, and the performance quality of loud speaker is to sound quality
Influence it is very big.Bugle can be set usually in loud speaker, increase amplifying effect.In modern public address application, to the skill of public address
Art requirement is higher and higher, not only meets sound pressure level, more to meet the high-end technical indicators such as Sound image localization, the sound field uniformity.
Public address to meet large area place such as outdoor sports ground plays demand, mostly uses combination Hi-Mid disjunctor matrix bugle loudspeaker system
System.
The Chinese patent of Publication No. 202873035U discloses a kind of multichannel one bugle, including upper, middle and lower three
One is made in sound channel, respectively low, senior middle school, the combination of bass bugle.Stroke to flange be in upper and lower two flanges line midpoint or
In the horizontal symmetry-line at midpoint so that three acoustic centres coincide into a bit, become point sound source；The upper flaring face of upper sound channel is under
The lower flaring face of sound channel is inclined 5 ° upper, inclined 12 ° lower respectively, and middle sound channel refers to 5 ° of downward bias off axis；0 ° of the outer rim of upper lower flange,
Each at 180 ° there are one convexes, are matched with locating slot in shell.
However, using the multichannel one bugle of above-mentioned technical proposal, when sound is propagated at each bugle, Neng Goushi
The complementation when propagating of existing senior middle school's bass is interfered, and still, when sound starts to propagate at point sound source, sound can not be ensured each
Uniform transmission is spread in a sound channel, diffusion is uneven so that sound is in transmission process because of the uneven generation inside bugle
Path difference causes the time difference, phase etc., so as to cause phase distortion, causes Sound image localization inaccurate, interference is serious, and sound quality is not
Smooth-going.
Utility model content
The utility model provides a kind of loud speaker and amplifies bugle, has the uniform expansion for ensureing middle pitch in transmission process
It dissipates, the advantages of wide coverage, solve above-mentioned traditional integrated bugle in the prior art causes because sound dispersion is uneven
Sound quality irregularity the technical issues of.
In order to solve the above technical problems, a kind of technical solution provided by the utility model is：A kind of loud speaker expansion is provided
Sound bugle, including middle pitch angle of flare are provided with sound channel in the middle pitch angle of flare, and the sound channel is along bugle extension side
Middle pitch pronunciation mouth is formed to through middle pitch angle of flare and in its tail end, phase plug is provided at the middle pitch pronunciation mouth.
In the specific implementation, sound enters angle of flare to the utility model from middle pitch pronunciation mouth along the periphery of phase plug
It is interior, it is close to angle of flare inner wall when propagating, ensure that the uniform diffusion of middle pitch, improves sound quality.
Above-mentioned loud speaker amplifies bugle, and the one side that the phase plug is contacted with middle pitch pronunciation mouth is provided with middle pitch and leads phase
Angle.When sound enters middle pitch angle of flare from the periphery of phase plug, along middle pitch lead phase angle and middle pitch pronunciation mouth between gap into
Enter in middle pitch angle of flare, diffusion is uniform.
Above-mentioned loud speaker amplifies bugle, and the phase plug is arranged to pronounce at mouth in middle pitch by screw.
Above-mentioned loud speaker amplifies bugle, and high pitch angle of flare, the sound channel edge are provided on the middle pitch angle of flare
High pitch angle of flare extending direction forms high pitch pronunciation mouth through high pitch angle of flare and in its tail end.Wherein, sound channel is in height
The tail end of sound angle of flare forms high pitch pronunciation mouth, and the bugle that originally amplifies can spread middle pitch and high pitch simultaneously.
Above-mentioned loud speaker amplifies bugle, and the inner wall of the middle pitch angle of flare and high pitch angle of flare is in paraboloid structure, should
Paraboloid extends along the external of the two sides of the middle pitch angle of flare and high pitch angle of flare.Sound wave communication process in angle of flare
In, sound wave is spread along paraboloid towards the both sides of bugle, and the diffusion angle of sound is big, wide coverage.
Above-mentioned loud speaker amplifies bugle, is provided on the outer wall of the middle pitch angle of flare and reinforces ripple muscle and side is reinforced
Muscle.
Above-mentioned loud speaker amplifies bugle, and the outer wall of the high pitch angle of flare is provided with uniformly distributed reinforcing rib.
Compared with prior art, the advantageous effect acquired by the utility model is：In middle pitch angle of flare and high pitch angle of flare
Inwall processing at paraboloid structure, improve sound dispersion angle, increase sound coverage area；Pass through the knot of phase plug
Structure so that sound is spread uniformly in middle pitch angle of flare, sound quality smooth-going.
Description of the drawings
Fig. 1 is the structural exploded view of the utility model embodiment；
Fig. 2 is the backsight structural representation of the utility model embodiment；
Fig. 3 is the forward sight structural schematic diagram of the utility model embodiment.
Specific implementation mode
Below in conjunction with the accompanying drawings and embodiment is described further the utility model.
Embodiment
Shown in Fig. 3, a kind of loud speaker amplifies bugle, including middle pitch angle of flare 1, in the middle pitch angle of flare 1
It is provided with sound channel 3, the sound channel 3 forms middle pitch along bugle extending direction through middle pitch angle of flare 1 and in its tail end
Pronounce mouth 11, and phase plug 12 is provided at the middle pitch pronunciation mouth 11.The setting of phase plug 12 so that sound wave is even into middle pitch
It is spread in angle of flare 1 and in its inner wall, diffusion angle is big, sound wide coverage.
