Basin is directly connected with baffle 20 also and external communication, and in the present embodiment, guard 30 covers two installing holes 21, the setting of guard 30
It is then that protection speaker is not affected by, reduces the damage of cone, can effectively prevent dust through installing hole simultaneously
21 enter inside audio amplifier.
The offering the sound being to send for audio amplifier and can effectively pass of mesh 31 on guard 30, guard 30 is curved
Arrange so that the moulding of whole guard 30 is more attractive in appearance, and mesh 31 is closely to arrange, and realizes the mesh that guard 30 is dust-proof further
's.
As shown in Figure 1, Figure 2 with shown in Fig. 5, it is preferable that baffle 20 lateral symmetry offers for UNICOM's containing cavity 40 with outside
Two leading note grooves 23 in space, two leading note grooves 23 are between paraphase hole 22 and installing hole 21, and leading note groove 23 is arranged in class sector,
All it is installed with in each leading note groove 23 in horizontally disposed multiple leading note plates 231.
Offering so that containing cavity 40 is connected with the external world of leading note groove 23, beneficially the circulation of air-flow, improves audio amplifier
Acoustical quality.There is in the most also making the containing cavity 40 of audio amplifier the environment of relatively dry, the electronic component of protection audio amplifier, improve
Service life.
In the present embodiment, preferred leading note groove 23 is arranged in class sector, handsome in appearance, can change as required during actual production
The shape of leading note groove 23, does not limits.Wherein, leading note groove 23 is not covered by guard 30, direct and space outerpace UNICOM.
The effect guiding and reinforcing is played in the setting of leading note plate 231, reasonable in design and easy to process.
As shown in Figure 2 and Figure 5, it is further preferred that baffle 20 bottom symmetrical offers two auxiliary tanks 24, each auxiliary tank
The multiple accessory plates 241 being inclined to set all it are installed with in 24.
Auxiliary tank 24 is covered by guard 30, not direct and space outerpace UNICOM, but the setting of auxiliary tank 24 and leading note
Groove 23 functional similarity, auxiliary tank 24 offer the circulation adding air blast further, the arranging of accessory plate 241 play equally guiding with
And the effect reinforced, reasonable in design.
As shown in Figures 6 to 9, it is preferable that the lateral surface spaced set of the first handle 50 has string the first fin 51,
