Abstract
Disclosed in the utility model is a horn assembly that comprises a horn, a support, and a circuit board. An accommodation space is formed by encircling of the support and the circuit board; and the horn is arranged inside the accommodation space, so that the accommodation space is separated into a front acoustic chamber and a rear acoustic chamber. And the support includes a top, a first sidewall and a second sidewall; the front acoustic chamber is arranged between the horn and the first sidewall; and the rear acoustic chamber is arranged between the horn and the second sidewall. According to the horn assembly provided by the utility model, the front acoustic chamber and the rear acoustic chamber are respectively arranged at the left and right sides of the horn. When the horn assembly is assembled in electronic equipment, the small internal space in the electronic equipment can be occupied, so that other components around the horn can be arranged and stacked successfully. Moreover, the volume of the rear acoustic chamber is larger than that of the front acoustic chamber, thereby obviously improving the low frequency effect of the horn assembly and thus improving the tone qualities of the horn assembly and the electronic equipment.

Embodiment
Combine accompanying drawing that the utility model is done further explain through embodiment below.
The utility model horn assembly is separately positioned on preceding sound chamber and sound chamber, back the left and right sides of loudspeaker; Also can make the volume of the volume in sound chamber, back greater than preceding sound chamber; Reduced the assembly space that horn assembly takies in electronic equipment; The layout of being convenient to other components and parts with pile up, can keep or improve simultaneously the tonequality of horn assembly.
First embodiment:
Horn assembly shown in Figure 1 mainly comprises loudspeaker 1, support 2, circuit board 3, vibrating diaphragm 4 and foam 5, and wherein, support 2 is enclosed an accommodation space with circuit board 3, and loudspeaker 1 are arranged in this accommodation space, and accommodation space is separated into preceding sound chamber 7 and sound chamber, back 8.
Support 2 comprises top 21, the first side wall 23, second sidewall 22, and the first side wall 23 is connected with vertical bending the in the two ends at top 21 respectively with second sidewall 22.Support 2 also can comprise dividing plate 24 and fixed head, and the two all is arranged between the first side wall 23 and second sidewall 22 and is parallel with the first side wall 23 or second sidewall 22, and the both sides that are respectively applied for loudspeaker 1 position.The parts that the support 2 of this execution mode is formed in one, the first side wall 23 and second sidewall 22 21 extend out from the top respectively, and support 2 also can adopt a plurality of parts assemblings to form certainly.Circuit board 3 is a pcb board, its with loudspeaker 1 between circuit be connected.Support 2 passes through foam 5 secure seal with the junction that circuit board 3 surrounds, and to guarantee tonequality, foam 5 also can adopt other seals to replace certainly.
The horn assembly of this execution mode is separately positioned on loudspeaker 1 both sides with preceding sound chamber 7 and sound chamber, back 8; With in the prior art before sound chamber 7 and back sound chamber 8 separate respectively in the mode of the rear and front end of loudspeaker 1 and compare, make the global shape of horn assembly be the less relatively square shape of thickness.When being assemblied in this horn assembly in the electronic equipment; When the finite volume of electronic equipment own, and though the volumetric ratio in sound chamber, front and back for example what, and loudspeaker be installed in the accommodation space concrete mode how; Because horn assembly integral body is thinner; Less in the thickness direction occupation space, can both save assembly space to a certain extent, the smooth layout of other components and parts around convenient with pile up.
Generally, the high frequency Fh quality of the volume size in preceding sound chamber 7 decision horn assembly, the low frequency F0 quality of the volume size decision horn assembly in back sound chamber 8.Separate in the horn assembly of the rear and front end of loudspeaker 1 in a kind of preceding sound chamber of using always in the prior art 7 and sound chamber, back 8; Keep at the volume in preceding sound chamber 7 under a certain size the situation, reduce the overall volume of horn assembly, just reduce the thickness of square shape through the volume that dwindles sound chamber, back 8; With the normal arrangement that adapts to other components and parts around the horn assembly in the electronic equipment with pile up; Though the structural volume of back sound chamber 8 correspondences of this horn assembly is less relatively, the inner space that takies when being assemblied in the electronic equipment is corresponding less, yet its tonequality is relatively poor; Bandwidth is narrower, and especially bass effect is bad.And in this execution mode; Volume in preceding sound chamber 7 keeps under a certain size situation with the elimination sharp and rounded sounds, and the volume in back sound chamber 8 is greater than the volume in preceding sound chamber 7, and low frequency F0 will change to direction less than normal; Thereby effectively promote the bass effect of horn assembly, reach the purpose of improving tonequality.Therefore the horn assembly of this execution mode is not only taken into account the convenience of horn assembly assembling, and has significantly improved the tonequality of loudspeaker and electronic equipment, can strengthen user experience.
Through test; Please refer to the frequency response curve and the distortion curve of Fig. 3 and this execution mode horn assembly shown in Figure 4; Be used to reflect reduction characteristic and the distortion rate of horn assembly for the voice signal of different frequency; It is thus clear that the frequency response curve of this horn assembly is relatively straight, distortion rate is relatively low, and especially low-frequency effect is better.Sound chamber 7 formed the sounding pattern of rear side sounding before the sound that the present embodiment horn assembly sends loudspeaker 1 imported from the back side; With prior art the emergence pattern that the preceding sound chamber of the positive importing of sound loudspeaker forms positive positive sounding is compared; Tonequality remains unchanged basically; Can satisfy user's demand fully, overcome people and thought the acoustical quality very poor technological prejudice of loudspeaker back side sounding for a long time.
Second embodiment:
As shown in Figure 2; What present embodiment was different with first embodiment is to turn loudspeaker 1 to be arranged on the direction that is provided with in the support 2; The front end face that makes loudspeaker 1 is towards circuit board 3; The back side is towards the top 21 of support 2, and the leading note gap of reserving between dividing plate 24 and the circuit board 1 can import preceding sound chamber 7 from positive (being front end face) with the sound that loudspeaker 1 send, thereby forms the sounding pattern of the face side sounding of horn assembly.In this execution mode, vibrating diaphragm 4 can and circuit board 3 between reserve certain interval, sound that loudspeaker 1 send can be got into through this gap smoothly before sound chamber 21, further improve tonequality.
The Fig. 3 of the frequency response curve of the horn assembly of present embodiment and distortion curve and first embodiment and result shown in Figure 4 are similar.
The horn assembly of the above two kinds of embodiment of the utility model can be widely used in the various electronic such as mobile phone, notebook computer, broadcast receiver, media player as built-in loudspeaker; Not only can save the inner space of equipment; The development trend that adapts to electronics miniaturization and precise treatment; Can also improve the tonequality of loudspeaker, satisfy user's user demand.
Above content is the further explain that combines concrete execution mode that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
