A kind of loudspeaker eqalizing cricuit, including eqalizing cricuit ontology, eqalizing cricuit body central offer through-hole, and eqalizing cricuit ontology encloses
Through-hole is provided with several gas chamber channels, gas chamber channel includes entering tone channel, refraction inclined-plane and channel of speaking, and refraction inclined-plane is solid
Fixed setting offers entering tone mouth, offers and speak on channel of speaking in entering tone channel and channel junction of speaking on entering tone channel
Mouthful, entering tone mouth is uniformly distributed around through-hole is rounded, and mating above gas chamber channel to be provided with covering plate, covering plate is annular in shape,
And central protuberance and to both sides angled transition, entering tone mouth is arranged on covering plate.
Further, covering plate includes the first inclined-plane and the second inclined-plane, and entering tone channel includes the first entering tone channel and second
Entering tone channel, the first inclined-plane are provided with the first entering tone channel, and the second inclined-plane is provided with the second entering tone channel, the first entering tone channel with
Second entering tone channel relative spacing is uniformly distributed.
Further, channel of speaking includes that the first channel and second of speaking is spoken channel, and the first channel of speaking enters with first
Sound channel is fixedly connected, and the second channel of speaking is fixedly connected with the second entering tone channel.
Further, entering tone channel is specially into cylinder record.
Further, refraction inclined-plane and passage bottom angular range of speaking are 100-150 degree.
The utility model has the advantages that
Entering tone mouth is uniformly distributed around through-hole is rounded, therefore the length in channel of speaking is all the same, will not generate phase difference,
This improves output acoustic wave energy and bandwidth；It is additionally arranged refraction inclined-plane and covering plate, the gas chamber channel interior turnover made is smooth, by
Originally 90 degree of corners become tiltedly improving passability of the sound wave in gas chamber channel, therefore the smooth effect of air-flow is in energy into formula
On expression effect it is preferable；The entering tone mouth of a variety of different locations is provided on covering plate simultaneously, improve eqalizing cricuit guiding and
Direction propagation sound wave ability.
Detailed description of the invention
Fig. 1 is that the utility model has assembled entirety perspective view；
Fig. 2 is members structural schematic diagram in the utility model；
Fig. 3 is the side structure schematic view of Fig. 2；
Fig. 4 is gas chamber channel side structure schematic view in the utility model.
Wherein, through-hole 1, gas chamber channel 2, entering tone channel 3, entering tone mouth 31, the first entering tone channel 32, the second entering tone channel
33, inclined-plane 4 is reflected, channel 5 of speaking, outlet sound mouth 51, first speaks channel 52, and second speaks channel 53, and covering plate 6, first tiltedly
Face 61, the second inclined-plane 62.
Specific embodiment
By make the structure feature to the utility model and the effect of being reached have it is further understand and understanding, to compared with
Good examples and drawings cooperate detailed description, are described as follows:
As shown in Figures 1 to 4, a kind of loudspeaker eqalizing cricuit, including eqalizing cricuit ontology, the eqalizing cricuit body central open up
There is through-hole 1, as the improvement of the utility model, eqalizing cricuit ontology is provided with several gas chamber channels 2 around through-hole 1, and gas chamber is logical
Road 2 includes entering tone channel 3, refraction inclined-plane 4 and channel 5 of speaking, and refraction inclined-plane 4 is fixed at entering tone channel 3 and channel 5 of speaking
Junction offers entering tone mouth 31 on entering tone channel 3, and outlet sound mouth 51 is offered on channel 5 of speaking, and entering tone mouth 31 surrounds through-hole 1
