Description

A kind of two-way speaker
Technical field
The present invention relates to electroacoustic field, particularly relate to a kind of two-way speaker.
Background technology
Along with electronic consumer products such as mobile phone, flat board, portable computer etc. is increasingly towards miniaturization, lightening direction Development, people are more and more higher to the requirement of electronic product pronunciation equipment, it is desirable to sound effect is good, tonequality is good.Stereo recording In journey, sound is assigned to two independent sound channels, such that it is able to reach good sound locating effect, meets people to a left side The requirement that the sense of R channel position is experienced.Reach stereosonic sound effect, at least need two loudspeaker units, i.e. L channels Loudspeaker unit and right channel loudspeaker unit.In theory, the volume in sound chamber is the biggest, and loudspeaker unit performance is the best, sound Effect is the best, is affected yet with by complete machine layout and small ultra-thin, the configuration design of speaker and sound cavity space ten Dividing limited, the loudspeaker unit of left and right acoustic channels is difficult to accomplish concordance, and sound can substantially feel the situation having small one and large one sometimes. Normal human ear is 3dB to the sense of sound, i.e. left and right acoustic channels difference have 3dB or above just can feel sound is discord, as Really the loudspeaker unit dischargeable capacity difference one times then sound intensity of left and right acoustic channels has the difference of 6dB.
As it is shown in figure 1, loudspeaker unit includes upper casing 1, lower casing 2, loudspeaker unit 3, FPC plate 4 and connects wire 5, on Shell 1 and lower casing 2 constitute loudspeaker unit sound chamber, and loudspeaker unit 3 is positioned in sound chamber, the loudspeaker unit sound chamber of present electronic product Volume is typically designed 0.5～1.5cm3, i.e. 1cm3Left and right.If as in figure 2 it is shown, the sound chamber of left channel loudspeaker unit 10 is effective Volume is 0.7cm3, the sound chamber dischargeable capacity of right channel loudspeaker unit 20 is 1.2cm3, when both use the loudspeaker list of same specification During unit, its sound difference there are about 5dB, and sound effect is poor.Prior art generally uses the interior wall thickness reducing loudspeaker unit casing Increasing sound chamber volume, effect is extremely limited, needs to change Design of Dies, relatively costly, and casing the thinnest after can affect product Intensity and reliability；Also the volume by the bigger loudspeaker unit sound chamber of reduction is had to make the two close, although this way can To ensure two channel sound balances, but after sound chamber diminishes, the performance of loudspeaker unit can be impacted, the overall sound of speaker Effect can decline.
Summary of the invention
The technical problem to be solved is: provide the two-way speaker that a kind of concordance is good.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of two-way speaker, including first Loudspeaker unit and the second loudspeaker unit, described first loudspeaker unit includes the first sound chamber, described second loudspeaker unit Including the second sound chamber, described second sound chamber is more than the first sound chamber, and it is cotton that described first sound intracavity is provided with tuning.
Further, the size that described tuning is cotton is: VTuning is cotton=ρAir/ρTuning is cotton*(VSecond sound chamber-VFirst sound chamber), wherein VTuning is cottonRepresent The volume that tuning is cotton, ρAirRepresent atmospheric density, ρTuning is cottonRepresent tuning minuteness degree, VSecond sound chamberRepresent the effective volume in the second sound chamber, VFirst sound chamberRepresent the effective volume in the first sound chamber.
Further, described first sound chamber includes that upper casing and lower casing, described tuning cotton are positioned on described lower casing.
Further, described tuning cotton is positioned at turning and/or passage.
Further, described tuning cotton is invested on described lower casing by a layers of two-sided.
Further, described tuning cotton is that BASF is cotton.
Further, described tuning cotton is cuboid.
The beneficial effects of the present invention is: setting tuning at less sound intracavity cotton, the sound viscosity utilizing tuning cotton can Slowing down the propagation of sound, improve the sound concordance in two sound chambeies, the present invention need not the inner wall thickness of thinning casing, without It is modified to mould, easily realizes, low cost.

Detailed description of the invention
By describing the technology contents of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate attached Figure is explained.
The design of most critical of the present invention is: set tuning at less sound intracavity cotton, utilizes the sound viscosity that tuning is cotton The propagation of sound can be slowed down, improve the sound concordance in two sound chambeies, it is not necessary to the inner wall thickness of thinning casing, without change Mould, easily realizes, low cost.
Refer to Fig. 3 and Fig. 4, a kind of two-way speaker, including the first loudspeaker unit and the second loudspeaker unit, Described first loudspeaker unit includes that the first sound chamber, described second loudspeaker unit include the second sound chamber, and described second sound chamber is big In the first sound chamber, it is cotton that described first sound intracavity is provided with tuning.
Knowable to foregoing description, the beneficial effects of the present invention is: set tuning at the first less sound intracavity cotton, utilize and adjust The sound viscosity that sound is cotton, slow down the propagation of sound, is equivalent to increase the volume in the first sound chamber, can make the first sound chamber and The volume in the second sound chamber is close, improves the sound concordance in two sound chambeies.
Further, the size that described tuning is cotton is: VTuning is cotton=ρAir/ρTuning is cotton*(VSecond sound chamber-VFirst sound chamber), wherein VTuning is cottonRepresent The volume that tuning is cotton, ρAirRepresent atmospheric density, ρTuning is cottonRepresent tuning minuteness degree, VSecond sound chamberRepresent the effective volume in the second sound chamber, VFirst sound chamberRepresent the effective volume in the first sound chamber.
Seen from the above description, the volume size that tuning used is cotton is the density cotton by tuning and the first sound chamber and second The volume differences in sound chamber determines, volume that used tuning cotton can be more precisely calculated, and error is less, workable.
Further, described first sound chamber includes that upper casing and lower casing, described tuning cotton are positioned on described lower casing.
Further, described tuning cotton is positioned at turning and/or passage.
Seen from the above description, tuning cotton is located on lower casing, when being arranged on the turning in sound chamber or less leading to Time at road, its tuning effect is preferable.
Further, described tuning cotton is invested on described lower casing by a layers of two-sided.
Seen from the above description, in order to prevent, tuning is cotton to be shifted at sound intracavity, with sticking double faced adhesive tape on lower casing.
Further, described tuning cotton is that BASF is cotton.
Further, described tuning cotton is cuboid.
Seen from the above description, tuning cotton is designed as cuboid convenient calculating volume and cuts.
