Embodiment
Below in conjunction with drawings and embodiments, the invention will be further described.
Please join at the same time shown in Fig. 1-4, the present invention provides a kind of loudspeaker enclosure 100, including upper cover 1, lower cover 2, sounding monomer 3rd, sound passage 4 and reinforcement plate 5 are led.
The lower cover 2 is covered on the upper cover 1 and surrounds receiving space 10 jointly.The upper cover 1 and the lower cover 2 can be Integrative-structure, or Split type structure.
Specifically, the upper cover 1 is equipped with the supporting walls 11 of sounding monomer 3 described in face, the supporting walls 11 are annularly tied Structure, is used to support the sounding monomer 3.
To include the first Auxiliary support wall 111 and second auxiliary for the side for leading sound passage 4 that is connected to of the supporting walls 11 Supporting walls 112 are helped, the first Auxiliary support wall 111 and the second Auxiliary support wall 112, which are arranged at intervals, forms fracture 113.
The sounding monomer 3, which houses, to be fixed in the receiving space 10.Specifically, the sounding monomer 3 is fixed on institute State supporting walls 11 and form fixing seal.
The operatic tunes 6 and back cavity 101 before the receiving space 10 is separated into by the sounding monomer 3.
That is, the sounding monomer 3 is arranged at intervals with the upper cover 1 and surrounds the preceding operatic tunes 6 jointly;The hair Sound monomer 3 surrounds the back cavity 101 jointly with the upper cover 1 and the lower cover 2.
The sound passage 4 of leading is formed in the receiving space 10.Specifically, the sound passage 4 of leading is formed on described Lid 1, it can be an integral molding structure with the upper cover 1.
The sound passage 4 of leading is collectively forming ante-chamber 102 with the preceding operatic tunes 6, and the preceding operatic tunes 6 is in communication with the outside.
Specifically, in present embodiment, the sounding monomer 3 surrounds the preceding operatic tunes 6, institute jointly with the supporting walls 11 The operatic tunes 6 is connected by the fracture 113 with the sound passage 4 of leading before stating.
The reinforcement plate 5 is fixedly supported to the first Auxiliary support wall 111 and the second Auxiliary support wall at the same time The side of the 112 close lower cover 2.Being fixed on close to the side abutting for leading sound passage 4 for the sounding monomer 3 is described Reinforcement plate 5.
That is, the reinforcement plate is fixed in being abutted close to the side for leading sound passage 4 for the phonation unit 3 5, other sides of the sounding monomer 3, which abut, is fixed on the supporting walls 11, for example is formed by glued mode and supporting walls 11 Fixing seal.Said structure cause the sounding monomer 3 form the preceding operatic tunes 6 with the upper cover 1 after its periphery formed completely Fixing seal, realizes good waterproof effect.
In present embodiment, the thickness of the reinforcement plate 5 is the steel disc of 0.15mm, and certainly, its thickness and material are not It is limited to this, in principle more Bao Yuehao.The reinforcement plate 5 includes main part 51, extension 52 and strengthening portion 53.
The main part 51 is supported in the first Auxiliary support wall 111 and the second Auxiliary support wall 112 at the same time.
The main part 51 specifically includes in the Part I 511 of strip and bends extension by the Part I 511 Part II 512.The Part I 511 is supported in the first Auxiliary support wall 111 and the second Auxiliary support wall 112, the Part II 512 is embedded at described lead in the side wall of the close lower cover 2 of sound passage 4.The sounding monomer 3 is then Specific abut is fixed on this Part I 511.
The extension 52 includes two, is extended to form respectively by 51 both ends of main part bending.Two extensions Portion 52 is embedded in the first Auxiliary support wall 111 and the second Auxiliary support wall 112 respectively.The structure setting strengthens The fixing intensity of the main part 51 and the supporting walls 11, so as to improve the sounding monomer 3 by fixed stability.
The strengthening portion 53 from the main part 51 to it is described lead 4 direction of sound passage bending extend to form, the strengthening portion 53 are fixed on described lead on the side wall of the close lower cover 2 of sound passage 4.The setting of the strengthening portion 53 causes the main part 51 is more steady reliable, avoids because being made the main part 51 come off by external force and then influencing the acoustical behavior of the sounding monomer And water resistance.
More preferably, the strengthening portion 53 includes two and spaced setting.Specifically, the strengthening portion 53 is by described Two parts 512 extend to form.
In present embodiment, the reinforcement plate 5 and the supporting walls 11 and it is described lead sound passage 4 and be integrated be molded into Type, increases reliability of structure and stability.
The plastic structure of correlation technique, under same structural strength, the reinforcement plate 5 are substituted by the reinforcement plate 5 Thickness is much smaller than the thickness of plastic structure, and the thickness of plastic structure is at least 0.5mm in correlation technique, and the reinforcement plate 5 Thickness only 0.15mm, save plastic structure occupancy fracture more than 0.35mm height space, led equivalent to adding The height of sound passage 4, so as to add the volume of the ante-chamber 102 of the loudspeaker enclosure 100, and then effectively improves described The acoustical behavior of loudspeaker enclosure 100.
Compared with prior art, the one of sound passage is led described in abutting of the loudspeaker enclosure provided by the invention in the supporting walls Side sets the reinforcement plate, and make the sounding monomer is connected to the reinforcing plate close to the side support for leading sound passage Part forms fixation, and the supporting walls are fixed in other sides of the sounding monomer by gluing, realizes the sounding monomer Periphery be completely fixed, reached water resistance, and good water-proof effect;Correlation technique plastic cement knot is substituted by the reinforcement plate Structure, under same structural strength, the thickness of the reinforcement plate is much smaller than the thickness of plastic structure, and the height space of saving can make institute State highly increases when leading the design of sound passage, so as to add the ante-chamber volume of the loudspeaker enclosure, and then effectively improves described The acoustical behavior of loudspeaker enclosure.
The foregoing is merely the embodiment of the present invention, is not intended to limit the scope of the invention, every to utilize this hair The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made, is directly or indirectly used in other relevant skills Art field, is included within the scope of the present invention.
