Embodiment 1
[0047] Such as figure 1 As shown, the first embodiment of the present invention provides a sounding apparatus 100, including: division unit 110, a treble sound structure 120, and a bass sound structure 130:
[0048] The division unit 110 connects the high tone sound structure 120 and the low tone sound symbol structure, the high tone sound structure 120 and the low tone sound structure 130 to each other, the treble sound structure 120 is a ring high-wave speaker, the bass The sound radiating end of the vocal structure 130 is provided to the ring high-tube.
[0049] The division unit 110 can distinguish the sound signal of the different frequency bands, which are enlarged, and then sent to the sound structure of the respective frequency band and reproduce, suitable for high quality sound, effectively improve the sound quality of the sounding device.
[0050] By setting the treble sound structure 120 and the bass sound structure 130, the sounding device 100 enables the output of the...
Embodiment 2
[0074] Such as Figure 7 , Figure 8 As shown, the present invention provides a wind tunneling system including: a connection device 200, a control device 300, and a sound device 100:
[0075] The connecting device 200 is connected to the sounding device 100, which is configured to control the sound intensity of the havan device 100.
[0076] The control device 300 can be placed outside the flow field, convenient for the user to operate; when the test, the sounding device 100 is fixed in the flow field through the connecting device 200.
[0077] The wind tunneling device is formed by the sound tuning device and the connecting device to obtain a test device that can be applied to the short-tank sound of the engine in the sound tunnel, avoiding the high cost of real flight, high test difficulty, difficult to implement, It has the advantage of low experimentation cost, simple and easy, and reliable and easy to test.
[0078] Typically, the maximum sound intensity of the sounding device...
