What the inclination of body 210 extended to form leads sound wall 250.Acoustic aperture 241 is offered out on side wall 240.It leads sound wall 250 and leads sound wall 250 substantially
In tabular, extended to form from the side wall 240 for offering out 241 side of acoustic aperture towards the inclination of framework 210.
The generally rectangular shaped cyclic structure of framework 210, internal the first mounting hole formed for accommodating loudspeaker monomer 100
212.Side in framework 210 close to roof 230 is formed with the groove 211 of annular, and the becket 220 is fixed by groove 211
In framework 210.
Becket 220 includes sheet metal ring body 222 and the pin part connecting with the sheet metal ring body 222
223, pin part 223 is bent along the edge of sheet metal ring body 222 to be extended, fixed by aforementioned grooves 211 and shell 200
Connection.Specifically, pin part 223 is plugged in groove 211, and sheet metal ring body 222 partially protrudes into the first mounting hole 212
In.Loudspeaker monomer 100 is fixed in the sheet metal ring body 222.In such embodiment, sheet metal ring body 222 with
Biggish location area can be formed between loudspeaker monomer 100, and then promotes the positioning accuracy of loudspeaker monomer 100；Meanwhile
Pin part 223 and framework 210 have biggish connection area, and then promote the installation strength of sheet becket ontology 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 in channel 500 of speaking,
Sheet metal ring body 222 can be set to planar structure, i.e. face where sheet metal ring body 222 is plane.Into one
Step ground, face where pin part 223 can perpendicular to sheet metal ring body 222, in order to the processing of entire loudspeaker enclosure, and
And pin part 223 can also be optimized to the support effect of sheet metal ring body 222.
The region for corresponding to framework 210 in the roof 230 of shell 200 and leading sound wall 250 offers the second mounting hole 231.
Second mounting hole 231 is connected with the first mounting hole 212.Shell 200 further includes the first lid being mounted in the second mounting hole 231
Plate 300.First cover board 300 includes first cover board body 310 and the first sheet metal 320 with third mounting hole 311, the first gold medal
Belong to piece 320 to be installed in third mounting hole 311, the first cover board body 310 is mounted in the second mounting hole 231 and by welding in fact
Now it is fixedly connected with roof 230.First sheet metal 320 is with vibrating diaphragm 110 and 220 face of becket and interval is arranged.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 board 400 may include the second cover board body 410 and the second gold medal for 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 board sheet
Body 410 is realized by welding and is fixedly connected with the side wall 240 of shell 200.Preferably, in the present embodiment, the second cover board sheet
Body 410 is made of plastic material.
After assembling, interval setting forms ante-chamber, the becket 220, first between vibrating diaphragm 110 and the first sheet metal 320
It cover board 300, side wall 240 and leads sound wall 250 and together constitutes connection ante-chamber and the channel 500 of speaking of acoustic aperture 241 out.Due to gold
It is smaller to belong to the occupied space of ring 220, therefore compared to existing loudspeaker enclosure, speaking for the loudspeaker enclosure of invention offer is logical
Road 500 is bigger (can specifically be presented as that the height in channel 500 of speaking expands), and then is lifted out sound effective value.Specifically, in loudspeaking
, can be by the height increase at least 0.2mm in channel 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 adopting the above structure, it is also possible that channel 500 of speaking
The more flexible freedom of shape, be conveniently adjusted the channel 500 of speaking.
One
Optionally, above-mentioned first cover board body 310 and the first sheet metal 320 can be formed by the way of integrated injection molding,
Similarly, the second cover board body 410 and the second sheet metal 420 can also be formed by the way of integrated injection molding, framework 210 and gold
Belonging to ring 220 can also be formed by the way of integrated injection molding, enhance the structural strength of entire loudspeaker enclosure with this, while reducing and raising
The processing technology of sound device case, reduces its processing cost.In addition, work as shell 200 after adopting the above structure, in molded housing 200,
Mold positioning directly can be carried out by the first mounting hole 221, without being positioned by other structures, meanwhile, mold
Sliding block will not alleviate the burr generated at friction for the negative of processing quality with this with the friction of 420 large area of the second sheet metal
Face is rung.
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 can also be installed on the one side on the first cover board body 310 far from loudspeaker monomer 100.When using the former,
First sheet metal 320 will occupy a part of space, and the height in the channel 500 that causes to speak still has certain extending space；When
When using the latter, the setting of the first sheet metal 320 will lead to becoming large-sized for entire loudspeaker enclosure, cause loudspeaker enclosure in movement
Installation in equipment is restricted.
To solve the above-mentioned problems, in the embodiment of the present invention, the first cover board body 310 has third installation through-hole 311, the
One sheet metal 320 is installed in third installation through-hole 311.That is, opposite with the second cover board 400 in the first cover board 300
On direction, the first sheet metal 320 no longer additionally takes up space, so that the height in channel 500 of speaking can further expand
Exhibition.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
