Abstract
Provided is a loudspeaker with an inner-bracket-style vibration system. The loudspeaker comprises voice coils, a vibration plate, positioning support sheets, magnetic circuit systems and cone frames, wherein outer rings of the positioning support sheets are attached to the inner walls of the cone frames, and the outer circumference of the vibration plate is attached to the tops of the cone frames. The loudspeaker further comprises inner brackets. Each inner bracket consists of a ring-shaped top wall, an inner conical wall formed at the inner ring of the ring-shaped top wall, and an outer conical wall formed at the outer ring of the ring-shaped top wall. The voice coils are attached on the inner conical walls of the inner brackets. Inner rings of the positioning support sheets are attached to the outer conical walls of the brackets. The ring-shaped top walls of the brackets are attached on the lower surface of the vibration plate. The bottoms of the cone frames are attached to the bottoms of the magnetic circuit systems, and the magnetic circuit systems are positioned inside the cone frames. The height of the loudspeaker can be shortened, and the volume that the loudspeaker occupies a sound box is reduced, and cost of the whole set of a sound box system is lowered.
Description
Technical field:
The utility model relates to the stereo set technical field, specifically is a kind of loudspeaker with interior bracket type vibrational system.
Background technology:
The vibrational system of present traditional loudspeaker usually by a voice coil loudspeaker voice coil 2 ', oscillating plate 1 ', dust cap 3 ', one or more locating branch slice 4 ' constitute.Wherein voice coil loudspeaker voice coil 2 ', oscillating plate 1 ' root, locating branch slice 4 ' the inner ring position stick together with glue; Dust cap 3 ' then be bonded at oscillating plate 1 ' go up and be positioned at oscillating plate 1 ' the top of root; With prevent dust fall into magnetic circuit system 6 ' the gap in, avoid the generation of different sound.For supporting whole vibrational system, the basin frame 5 of loudspeaker ' the be provided with step surface of direction bending in basin, locating branch slice 4 ' the outer ring then be bonded on this step surface, the basin frame 5 of loudspeaker ' the bottom then be bonded in magnetic circuit system 6 ' the top.So just formed vibrational system be positioned at basin frame 5 ', basin frame 5 ' then the be positioned at location arrangements of magnetic circuit system 6 ' top.Concrete structure sees Fig. 1 for details.
When loudspeaker use above structural vibrations system, because of basin frame 5 ' integral body is the cone shape with high height, and be positioned at magnetic circuit system 6 ' the top; Add upper vibrating plate 1 ' shape and basin frame 5 ' shape similar; Also be the cone shape with high height, loudspeaker assembling back whole height is higher like this, and volume shared in audio amplifier is also bigger; Volume and placement space to audio amplifier all have higher requirement, have also increased the cost of whole sound system simultaneously.
The utility model content:
The utility model technical issues that need to address are: a kind of height that reduces is provided, the volume that takies audio amplifier is reduced, reduce the loudspeaker of bracket type vibrational system in the band of cost of a whole set of sound system.
For solving the problems of the technologies described above; The utility model adopts a kind of like this loudspeaker with interior bracket type vibrational system, and it comprises voice coil loudspeaker voice coil, oscillating plate, locating branch slice, magnetic circuit system and basin frame, and the outer ring of described locating branch slice is bonded on the inwall of basin frame; The circumferential periphery of described oscillating plate is bonded in the top of basin frame; It also comprises carriage in, described in carriage constitute by an annular upper wall, the inner conical wall that takes shape in annular upper wall inner ring place, the male-tapered wall that takes shape in place, annular upper wall outer ring, in described voice coil loudspeaker voice coil is bonded on the inner conical wall of carriage; The inner ring of described locating branch slice is bonded on the male-tapered wall of interior carriage; The annular upper wall of carriage is bonded on the lower surface of oscillating plate in described, and the bottom of described basin frame is bonded in the bottom of magnetic circuit system, and described magnetic circuit system is positioned at the basin frame.
Described oscillating plate is a plate shape.
The cross section of described basin frame is half elliptic.
The utility model compared with prior art has the following advantages: the loudspeaker of bracket type vibrational system are because of having additional interior carriage in the band of the utility model, and the bottom of basin frame is bonded in the bottom of magnetic circuit system; Add that magnetic circuit system is positioned at the basin frame; Greatly reduce the height of whole loudspeaker like this, loudspeaker shared volume in audio amplifier is also less like this, need not the volume and the placement space of audio amplifier are had higher requirements; Compact overall structure has simultaneously reduced the cost of whole sound system.
As improvement, described oscillating plate is a plate shape, and compared with prior art, plate shape has further reduced height.
As further improvement, the cross section of described basin frame is half elliptic, and compared with prior art, half elliptic has further reduced height.
