Fig. 5 shows the half section structure diagram of shell body.The shell body designs for rectangular box, band on front panel
There are three manholes for loudspeaker installation, respectively installation through-hole 1, installation through-hole 2 403, installation through-hole 3 405, on
Panel is provided with the rectangular slot 401 for guidance panel installation, is provided with side panel and receives the recessed of box installation for wireless charging
Groove, rear board upper center inwardly have recess, stretched for pull bar, and the elongated slot being adapted to the rod assembly is provided with the middle part of lower end
406。
The high-frequency horn 102, intermediate frequency loudspeaker 103, Low frequency horn 104 are sequentially arranged at before the shell body 109
On plate, it is connected respectively with power amplifier circuit board 302；High-frequency horn 102 and the small volume of intermediate frequency loudspeaker 103, Low frequency horn 104 need
Low-frequency sound is played, so all bigger than both remaining between its bore, magnet, voice coil loudspeaker voice coil, diaphragm oscillations amplitude is larger, therefore body
Product is larger.
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 vibrating diaphragm back side occur bass sound wave can around the front of vibrating diaphragm, and with vibrating diaphragm front
The bass sound wave of generation is offset, and " acoustic short circuit " phenomenon occurs.
In order to avoid occur " acoustic short circuit phenomenon ", the utility model inside the shell body 109, Low frequency horn 104
Periphery, set dividing plate 304 to separate Low frequency horn, the grade sound-silencing measures of sound-absorbing sponge 305 are provided with dividing plate inwall, absorption is shaken

201；Fixture 202 is fixed on the rear board of shell body 109, and middle part is longitudinally arranged the chute being oriented to for pull bar, the drawing
Bar 203 longitudinally can pull out and withdraw along the chute.In order to avoid pull bar protrudes the shell body, the utility model embodiment
Rod assembly integrally embedded in the shell body backboard recess in.The part position of the rod assembly is without departing from shell body
The back side.
When needing to move pull bar sound equipment, pull bar 203 is pulled out along the chute, tilts and pulls the pull bar sound equipment；
Now, the support feet of pull bar sound equipment is not contacted with ground, and pull bar sound equipment will not be hindered to move；During static placement, pull bar sound equipment
Support feet contacts with ground, prevents pull bar sound equipment from sliding.
The wireless charging receives box 108 on the panel of the casing of sound equipment side, is internally provided with wireless charging and connects
Take-up circle, the wireless charging receive box output end and are connected with the battery.
Receive what box matched with wireless charging, also including the pull bar sound equipment also includes wireless charging base 501, nothing
Line charging base is built-in with wireless charging transmitting coil.
Most of wireless charging device is all to use Qi standard productions in the market, for versatility and in view of into
This factor, this wireless charging receiving coil used using new embodiment and the wireless charging transmitting coil meet Qi
Standard.
In 1.2 versions of Qi standards, the effective charging distance of highest is 45 millimeters, it is contemplated that charge efficiency factor, outer
The slight barrier of shell and 1.1 standards of compatible legacy version, when pull bar sound equipment is in charged state, the wireless charging base
Box is received with the wireless charging to be close to, the wireless charging transmitting coil is parallel with the wireless charging receiving coil, and phase
It is the distance between mutual to be less than or equal to 20 millimeters.
