Fig. 1 shows the pull bar acoustic structure schematic diagram with detachable operating case of the utility model embodiment, Fig. 7
Show the pull bar acoustic structure sectional view with detachable operating case of the utility model embodiment.The utility model is implemented
Example discloses a kind of pull bar sound equipment with rotary peripheral hardware base, including head unit, bottom plate, rod assembly；
The head unit includes shell body 101, battery 106, high-frequency horn 102, intermediate frequency loudspeaker 103, low frequency loudspeaker
104, power amplifier circuit board 107, decoder 108, operating case 110, battery 106, detachable operating case 109；
The shell body 101 is designed for rectangular box, and three manholes for loudspeaker installation, institute are carried on front panel
High-frequency horn 102, intermediate frequency loudspeaker 103, Low frequency horn 104 is stated to be sequentially arranged on the front panel of the shell body 101, and point
It is not connected with power amplifier circuit board 302；High-frequency horn 102 and the small volume of intermediate frequency loudspeaker 103, Low frequency horn 104 need to play low
Frequency sound, so all bigger than both remaining between its bore, magnet, voice coil loudspeaker voice coil, diaphragm oscillations amplitude is larger, thus volume compared with
Greatly.
In specific implementation, if Low frequency horn does not put into appropriate casing (dividing plate), its performance cannot play, low
Sound playback is bad, and sound seems extremely thin, and distortion is big, and transient response is also poor.Loudspeaker is driven by diaphragm oscillations
Air and sounding, vibrating diaphragm have tow sides, in vibration, will produce that two sizes are identical, but the acoustic irradiation of opposite in phase goes out
Go, because the wavelength of low-frequency sound wave is longer, the bass sound wave that the vibrating diaphragm back side occurs can be around the front of vibrating diaphragm, and with vibrating diaphragm just
The bass sound wave that face occurs is offset, and " acoustic short circuit " phenomenon occurs.
In order to avoid occur " acoustic short circuit phenomenon ", the utility model inside the shell body 101, Low frequency horn 104
