Embodiment
Hereafter the present invention will be further described with specific embodiment by reference to the accompanying drawings.
Embodiment 1:
With reference to figure 1-4, a kind of compact audio frequency paraphase module, comprising: loudspeaker unit 1 and audio frequency radiant tube 2;
Described audio frequency radiant tube 2 comprises the arrival end 21 that is communicated to described loudspeaker unit 1 rear, and one is positioned at the sound basin periphery of loudspeaker unit 1 and exports 22 with its coaxial arc-shaped arranged; Therefore, the sound wave at described loudspeaker unit 1 rear sends from described outlet 22 after the paraphase of audio frequency radiant tube, reaches approximate same sounding point with described loud speaker list 1 yuan.Therefore above-mentioned compact audio frequency paraphase module can reach the effect that gamut is similar to point sound source, and close to zero phase difference between the sound of senior middle school's low frequency, sound field and accuracy in pitch are obtained for reinforcement.
Because sound wave propagation in described audio frequency radiant tube 2 can be interfered and resistance, this interference and resistance increase along with the size increase of loudspeaker unit 1, and in order to pursue better tonequality, inevitably select larger sized loudspeaker unit, so in order to weaken above-mentioned interference and resistance, make following design to audio frequency radiant tube 2: described outlet 22 is greater than the width of arrival end 21 corresponding thereto on direction along the width on circular arc distribution arrangement, outlet 22 is less than the width of arrival end corresponding thereto on direction along the width in circular arc radial direction.By above-mentioned setting, the outlet 22 of audio frequency radiant tube 2 relatively and arrival end 21, length has been elongated, reduced on width, therefore become on the whole " flat ", such structure makes audio frequency radiant tube 2 while achieving gamut and being similar to the effect of point sound source, also can reduce above-mentioned interference and resistance as far as possible to the impact of sound wave.
In order to realize above-mentioned structure, described audio frequency radiant tube 2 has a changeover portion 23, its respectively with arrival end 21 with export 22 and be communicated with.The side that described changeover portion 23 is connected as described outlet 22 by the side be connected with described arrival end 21, has and increases gradually along the width on the circular arc distribution arrangement of outlet 22, along the structure of the tapering width in the radial direction of outlet 22.Therefore, the outlet 22 of audio frequency radiant tube 2 is elongated gradually in length, width is also reduced gradually.The design of this changeover portion 23 makes audio frequency radiant tube 2 while achieving gamut and being similar to the effect of point sound source, and audio frequency radiant tube 2 has the effect of homalographic transition or gradual change area transition.
The present embodiment also has following decision design:
The cross section of described arrival end 21 is oval, and its major axis is less than described outlet 22 along the width on circular arc distribution arrangement, and minor axis 21 is greater than the width that described outlet is radially gone up.Because the cross-sectional area of arrival end 21 will do greatly as far as possible, but for compact audio frequency paraphase module, its space is very limited, therefore takes the scheme of trading off in a limited space, and the cross section of arrival end 21 is done ovalisation.
In addition, described arrival end 21 is straight tube, with loudspeaker unit 1 towards consistent.
Embodiment 2
With reference to figure 5-6, the difference of the present embodiment and embodiment 1 is: described audio frequency radiant tube 2 is two, and the total length of two audio frequency radiant tubes 2 is not identical.And described audio frequency radiant tube 2 has the structure of telescopic.
Therefore, when the casing of the adaptive small volume of compact audio frequency paraphase module, the length of audio frequency radiant tube 2 can be lengthened to coordinate less box volume, in order to coordinate different volumes, just need different phase-reversing tube length, usually, many phase-reversing tubes can be designed to the same length, also can lengthen during lengthening simultaneously.And the present inventor proves by experiment, audio frequency radiant tube 2 can be different length, now, the audio frequency radiant tube of 2 different lengths is also 2-in-1, equivalence becomes a pipe, and the cavity of casing produces resonance, and 2 phase-reversing tubes lengthen respectively or shorten, adjustment can be made meticulousr, the required box volume coordinated can be adjusted to the most fast.
Embodiment 3
With reference to figure 7-8, the difference of the present embodiment and embodiment 1 is:
The cross section end of the arrival end 21 of described audio frequency radiant tube is circular, and its diameter is less than described outlet 22 along the width on circular arc distribution arrangement, and is greater than the width that described outlet 22 radially goes up.For the audio frequency paraphase module using large scale loudspeaker unit 1, its space is relatively large, the cross section of the arrival end 21 of audio frequency radiant tube can be designed to circle, obtain maximum cross-sectional area; Certainly, for the audio frequency paraphase module using large scale loudspeaker unit 1, it is also feasible that the design that continuation use cross-sectional area is ellipse obtains compact structure more.。
Embodiment 4
With reference to figure 9-10, the difference of the present embodiment and embodiment 2 is: the arrival end of described audio frequency radiant tube 21 is bend pipe, and its entrance has angle towards shape with loudspeaker unit 1, outlet and loudspeaker unit 1 towards consistent.In the present embodiment, described angle is 90 °.Certainly, also can be designed as other angle.Object arrival end 21 being designed to bend pipe is the length increasing audio frequency radiant tube.
Embodiment 5
With reference to figure 12-13, a kind of audio amplifier made by compact audio frequency paraphase module used described in embodiment 1, comprises casing 1, compact audio frequency paraphase module 2, sealing-in parts;
Described casing 1 has the hole 11 installed needed for described compact audio frequency paraphase module 2, described sealing-in parts are installed between described hole 11 and described compact audio frequency paraphase module 2.
As mentioned above, only need audio frequency paraphase module 2 to be connected with casing 1 and seal and can form a complete audio amplifier, therefore user can make a choice in tonequality and portability according to the needs of oneself, when needs portability, audio frequency paraphase module 2 and small box is sealed; When needs high tone quality, by audio frequency paraphase module 2 and large box sealing.In addition, design due to casing has not needed the technical problem considering electronics and acoustics, the designer of all trades and professions can design most suitable application as required, audio amplifier and existing product are organically combined, derive diversified application, while not destroying existing product outward appearance, hide well and placed audio amplifier.
Because the length of reflex cabinet sound intermediate frequency radiant tube 21 is relevant to the size of casing 1, therefore, box volume and the unmatched problem of radiant tube length is had if above-mentioned compact audio frequency paraphase module 2 is sealed on small box.For this problem, be two by the audio frequency radiant tube 21 of described compact audio frequency paraphase module 2 in the present embodiment, and the sound basin that its outlet is distributed in described loudspeaker unit 22 is peripheral.Certainly, also more according to needs, audio frequency radiant tube 21 can be designed to three or more, belong to simple replacement, repeat no more.
Like this, when the volume of described casing 1 and the total length of described audio frequency radiant tube 21 do not match, use described seal by the exit seal of one or more audio frequency radiant tube 21, the total length of audio frequency radiant tube 21 can be reduced, make audio frequency paraphase module 2 can adaptive large scale casing and small size casing.
