The present embodiment is 5mm.The width of the first spaced-apart beams between adjacent two the second senders 2 is less than or equal to 2.5mm, in this reality
Execute in example as 2.5mm.The width of the second spaced-apart beams 4 between adjacent two the second senders 2 in same annulus is less than
In 2.5mm, it is 2.5mm in the present embodiment.The edge of the second sender 2 is big from the width of the first outside radiation direction of sender 1
In equal to 4mm, it is 5mm in the present embodiment.The width of the 4th spaced-apart beams 7 between transition sender 6 and the first sender 1 is little
In equal to 2.5mm, it is 2.5mm in the present embodiment.The width of the 5th spaced-apart beams 8 between transition sender 6 and the second sender 2
Degree, less than or equal to 2.5mm, is 2.5mm in the present embodiment.Adjacent the 6th spaced-apart beams 9 between two transition senders 6
Width is less than or equal to 2.5mm, is 2.5mm in the present embodiment.Transition sender 6 along from the first sender 1 to external radiation side
To width more than or equal to 5mm, be 5mm in the present embodiment.
Certainly, this utility model is not limited to this, in other embodiments, and can be for different materials, according to requirement of strength
Layout sender and select suitably sized.
Sound box mesh cover shown by the present embodiment goes out sound structure and is particularly suited for corresponding woofer and passive speaker
Arrange.Because low-frequency sound frequency of vibration is relatively low, and sound wave has the most diffractive, the block of guard is relatively low, therefore corresponds to
The diameter of the first sender 1 that the sound box mesh cover of woofer and passive speaker goes out sound structure is less.
Additionally, in the periphery of the second sender 2, as required, also can arrange additional sender 10, additional sender 10 is also
For arcuate socket, concentric with the first sender 1 and the second sender 2.
Embodiment two
With reference to Fig. 2, in the present embodiment, being with the difference of embodiment one, the width of the first sender 1 is more than
In 19mm.Owing to the first sender 1 is relatively big, so being not provided with transition sender 6, between the first sender 1 and the second sender 2
The width of the 3rd spaced-apart beams 5 less than or equal to 3mm, be 3mm in the present embodiment.
Sound box mesh cover shown by the present embodiment goes out sound structure and is particularly suited for corresponding tweeter setting.Due to high frequency
Acoustical vibration frequency higher, sound wave directivity is relatively strong, therefore be the reduction guard stop to high frequency sound wave to greatest extent, correspondence
Being relatively large in diameter of first sender 1 gone out in sound structure of tweeter.

One go out sound structure 100, go out sound structure 200 corresponding to the second of tweeter and the 3rd go out sound corresponding to passive speaker
Structure 300, first go out sound structure 100, second go out sound structure 200 and the 3rd go out sound structure 300 all use above-described embodiment one or
Sound box mesh cover shown by embodiment two goes out sound structure, and second goes out the diameter of the first sender in sound structure 200 more than first
Go out sound structure 100 and the 3rd and go out the diameter of the first sender in sound structure 300.
This sound box mesh cover uses above-mentioned sound box mesh cover to go out sound structure, has not only had enough intensity but also penetrance shadow to sound
Ring less.Further, owing to low-frequency sound frequency of vibration is relatively low, sound wave has the most diffractive, and the block of guard is relatively low, therefore
Sound structure 100 and the 3rd going out the first of sound structure 300 and go out corresponding to passive speaker is gone out corresponding to the first of woofer
The diameter of sound hole is less；Accordingly, owing to the acoustical vibration frequency of high frequency is higher, sound wave directivity is relatively strong, is therefore maximum
Limit reduces the guard stop to high frequency sound wave, and the second of corresponding tweeter goes out the first sender in sound structure 200
It is relatively large in diameter.By the different settings to low frequency and high-frequency region, while proof strength, more reasonably reduce guard pair
The impact of acoustic transparency.
