The coil-moving speaker of phase plug.
A kind of coil-moving speaker using phase plug of the utility model includes T iron, magnet steel, washer, frame, plays wave, sound
Circle, cone, dust cap and phase plug；The T iron, the magnet steel, the washer and the frame form magnetic circuit system, the bullet
Wave, the voice coil, the cone, the dust cap and the phase plug form vibrational system；It is the T iron, the magnet steel, described
Washer and the frame are set gradually from top to bottom；The T iron run through the magnet steel and the washer, the T iron respectively with institute
Stating between magnet steel, the washer has gap；The outer edge for playing wave is connect with the frame；The voice coil is arranged in the magnetic
It is connect in the gap of road system with the inner hole for playing wave；The connection of the outer edge of the cone and the frame, it is described dust-proof
Cap is arranged in the cone and bonds with the voice coil；The phase plug is arranged in the cone and is located next to the voice coil
Top.
Preferably, the material that the T iron and the washer use is TQ235.
Preferably, the material of the magnet steel uses ferrite magnetic steel or alnico magnet.
Preferably, the material of the magnet steel is ferrite Y35.
Preferably, the material of the frame is cast aluminium.

Preferably, the material of the phase plug is papery.
Implement a kind of coil-moving speaker using phase plug of the utility model, there is technical effect beneficial below:
A kind of coil-moving speaker using phase plug of the utility model takes the phase that a papery is bonded on cone
Plug, this phase plug position is just in the top of dust cap and dust cap is bonded on voice coil, when loudspeaker is in high-frequency vibration,
It is a kind of high dither state at voice coil to dust cap, treble sounds are almost from dust cap toward external radiation, due on dust cap
Face is exactly phase plug, and when the sound wave that dust cap issues passes through the phase hole of phase plug, phase hole expands high frequency sound pressure level, to solve
Determined coil-moving speaker high frequency the not high problem of sound pressure level.
Detailed description of the invention
For more clearly bright the utility model embodiment or technical solution in the prior art, below will to embodiment or
