Embodiment
The present invention is described in further detail below by specific embodiment and with reference to accompanying drawing.
As Figure 1-5, the embodiments of the invention provide a kind of loudspeaker enclosure, the loudspeaker enclosure can be used as microphone device It is installed on mobile device, the mobile device can be specifically mobile phone, tablet personal computer, player etc. equipment.
Above-mentioned loudspeaker enclosure includes housing 200, the second cover plate 400 to form receiving space is assembled with housing 200 and is received Hold the loudspeaker monomer 100 in the receiving space, wherein:
Loudspeaker monomer 100 can be the preferable monomer structure of water resistance, and the structure of the loudspeaker monomer 100 is relatively more Sample, if can sounding, in a kind of concrete structure, the loudspeaker monomer 100 can include frame, in frame Magnetic circuit system, the vibrational system being connected above magnetic circuit system and with frame, frame herein can realize magnetic circuit system and After the installation of vibrational system, magnetic circuit system and vibrational system collective effect, it is possible to achieve sounding.Vibrational system can include being used for The vibrating diaphragm 110 of vibration sounding.
200 generally rectangular shaped shell structure of housing, side have opening, and the second cover plate 400 lid is located at the opening.Shell Side wall 240 that body 200, which includes roof 230, extension is bent from the edge of roof 230 forms, from roof 230 towards the second cover plate 400 The framework 210 of extension, framework 200 is installed on close to the becket 220 of the side of roof 230 and from side wall 240 towards frame What the inclination extension of body 210 was formed leads sound wall 250.Acoustic aperture 241 is offered out in side wall 240.Lead sound wall 250 and lead sound wall 250 substantially In tabular, it tilts what extension was formed from the side wall 240 for offering out the side of acoustic aperture 241 towards framework 210.
210 generally rectangular shaped cyclic structure of framework, it is internally formed the first mounting hole for housing loudspeaker monomer 100 212.Fixed in framework 210 close to groove 211 of the side of roof 230 formed with annular, the becket 220 by groove 211 In framework 210.
Becket 220 includes sheet metal ring body 222 and the pin part being connected with the sheet metal ring body 222 223, edge bending extension of the pin part 223 along sheet metal ring body 222, it is fixed by aforementioned grooves 211 and housing 200 Connection.Specifically, pin part 223 is plugged in groove 211, and the first mounting hole 212 is stretched into the part of sheet metal ring body 222 In.Loudspeaker monomer 100 is fixed in the sheet metal ring body 222.In such a embodiment, sheet metal ring body 222 with Larger location area can be formed between loudspeaker monomer 100, and then lifts the positioning precision of loudspeaker monomer 100;Meanwhile Pin part 223 has larger connection area with framework 210, and then lifts the installation strength of sheet becket body 222.It is above-mentioned Sheet metal ring body 222 can be curved-surface structure, for the ease of processing, while be further ensured that the space for passage 500 of speaking, Sheet metal ring body 222 can be arranged to planar structure, i.e., the face where sheet metal ring body 222 is plane.Enter one Step ground, face where pin part 223 can perpendicular to sheet metal ring body 222, in order to the processing of whole loudspeaker enclosure, and And support effect of the pin part 223 to sheet metal ring body 222 can also be optimized.
The region for corresponding to framework 210 in the roof 230 of housing 200 and leading sound wall 250 offers the second mounting hole 231. Second mounting hole 231 is connected with the first mounting hole 212.Housing 200 also includes the first lid being arranged in the second mounting hole 231 Plate 300.First cover plate 300 includes the first cover board body 310 and the first sheet metal 320 with the 3rd mounting hole 311, the first gold medal Category piece 320 is installed in the 3rd mounting hole 311, and the first cover board body 310 is arranged in the second mounting hole 231 and real by welding Now it is fixedly connected with roof 230.First sheet metal 320 and vibrating diaphragm 110 and the face of becket 220 and interval setting.It is preferred that Ground, in the present embodiment, the first cover board body 310 are made of plastic material, it is preferred to use elastic plastic material is made.
Second cover plate 400 can include the second cover board body 410 and the second gold medal being installed on the second cover board body 410 Belong to piece 420, the second sheet metal 420 and the first sheet metal 320 are positioned opposite on the direction of vibration of loudspeaker monomer 100.Second Cover board body 410 offers the 4th mounting hole 411, and the second sheet metal 420 is installed in the 4th mounting hole 411.Second cover plate sheet Body 410 is realized and is fixedly connected with the side wall 240 of housing 200 by welding.Preferably, in the present embodiment, the second cover plate sheet Body 410 is made of plastic material.
It is arranged at intervals after assembling, between the sheet metal 320 of vibrating diaphragm 110 and first and forms ante-chamber, the becket 220, first Cover plate 300, side wall 240 and lead sound wall 250 and together constitute connection ante-chamber and go out the passage 500 of speaking of acoustic aperture 241.Due to gold The space belonged to shared by ring 220 is smaller, therefore logical compared to existing loudspeaker enclosure, speaking for the loudspeaker enclosure of invention offer Road 500 is bigger (can specifically be presented as that the height for passage 500 of speaking expands), and then is lifted out sound effective value.Specifically, raising one's voice , can be by the height increase at least 0.2mm for passage 500 of speaking in the case that the total height of device case is constant, this improvement will be to raising The sound effective value that goes out of sound device case plays significant improvement result.In addition, after using said structure, it is also possible that passage 500 of speaking Shape more flexibly freely, be conveniently adjusted the passage 500 of speaking.
One
Alternatively, the above-mentioned sheet metal 320 of first cover board body 310 and first can be molded by the way of integrated injection molding, Similarly, the second cover board body 410 and the second sheet metal 420 can also be molded by the way of integrated injection molding, framework 210 and gold Category ring 220 can also be molded by the way of integrated injection molding, strengthen the structural strength of whole loudspeaker enclosure with this, while reduce and raise The processing technology of sound device case, reduces its processing cost.In addition, after housing 200 is using said structure, in molded housing 200, Mould positioning directly can be carried out by the first mounting hole 221, without being positioned by other structures, meanwhile, mould Sliding block will not with the friction of the large area of the second sheet metal 420, with this alleviate at friction caused by burr for the negative of crudy Face rings.
It is to be appreciated that above-mentioned first sheet metal 320 can be installed on the first cover board body 310 towards loudspeaker monomer 100 one side, the one side away from loudspeaker monomer 100 on the first cover board body 310 can also be installed on.When using the former, First sheet metal 320 will take a part of space, and the height for the passage 500 that causes to speak still has certain extending space;When During using the latter, the setting of the first sheet metal 320 will cause becoming large-sized for whole loudspeaker enclosure, cause loudspeaker enclosure in movement Installation in equipment is restricted.
In order to solve the above problems, in the embodiment of the present invention, the first cover board body 310 has the 3rd installation through-hole 311, the One sheet metal 320 is installed in the 3rd installation through-hole 311.It is that is, relative with the second cover plate 400 in the first cover plate 300 On direction, the first sheet metal 320 no longer additionally takes up space, and then the speak height of passage 500 is further expanded Exhibition.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
