Abstract
The utility model discloses a dual-driver loudspeaker, aiming at providing a dual-driver loudspeaker with high conversion efficiency and sensitivity, compact structure and large driving force. The dual-driver loudspeaker comprises a bracket; a magnetic cover is arranged behind the bracket; an alnico and a pole shoe are fixed in the magnetic cover; diaphragm voice coils are arranged at the circumference of the alnico and the pole shoe; and the diaphragm voice coils are connected with the diaphragm before the pole shoe. The dual-driver loudspeaker is characterized in that the diaphragm is simultaneously connected with two diaphragm voice coils; each diaphragm voice coil is driven by the magnetic cover, the alnico and the pole shoe and is arranged in the same bracket. In the utility model, as the diaphragm is simultaneously driven by two diaphragm voice coils, the driving force on the diaphragm voice coil is increased, the power and the sensitivity of the loudspeaker are improved greatly, and the effect of small dimension and large power is achieved.
Description
Technical field
The utility model relates to loud speaker, relates in particular to a kind of dual-drive speaker.
Background technology
It includes support common loud speaker, and support is the magnetic cover at the back, and magnetic cover internal fixation has magnet steel, pole piece, is the vibrating diaphragm voice coil loudspeaker voice coil around magnet steel and the pole piece, and the vibrating diaphragm of vibrating diaphragm voice coil loudspeaker voice coil and pole piece front is connected.The loud speaker of this routine gives the actuating force of vibrating diaphragm voice coil loudspeaker voice coil little, and the conversion efficiency and the sensitivity of loud speaker are low, for the actuating force that obtains big vibrating diaphragm voice coil loudspeaker voice coil can only realize that what bring thus is that the loud speaker volume is big, cost is high through the size that increases loud speaker.
The utility model content
The purpose of the utility model provides a kind of conversion efficiency and highly sensitive, compact conformation, dual-drive speaker that actuating force is big.
In order to achieve the above object, the technical scheme of the utility model is: include support, support is the magnetic cover at the back; Magnetic cover internal fixation has magnet steel, pole piece; Around magnet steel and the pole piece is the vibrating diaphragm voice coil loudspeaker voice coil, and the vibrating diaphragm of vibrating diaphragm voice coil loudspeaker voice coil and pole piece front is connected, and it is characterized in that described vibrating diaphragm is connected with two cover vibrating diaphragm voice coil loudspeaker voice coils simultaneously; Every suit vibrating diaphragm voice coil loudspeaker voice coil is driven by magnetic cover, magnet steel and pole piece respectively, and is installed in the same support.
Dual-drive speaker according to such scheme is made because vibrating diaphragm has two cover vibrating diaphragm voice coil loudspeaker voice coils to drive simultaneously, has strengthened the actuating force to the vibrating diaphragm voice coil loudspeaker voice coil, and the power of loud speaker and sensitivity also improve greatly, have reached the powerful effect of small size.
