Abstract
The utility model relates to a full voice-frequency coaxial loudspeaker of an outer magnet type, which is formed by that a lower leading pole plate of a low-frequency loudspeaker unit body is connected with a mid-frequency loudspeaker unit body which has uniform axle center and opposite magnetic pole with the low-frequency loudspeaker unit body, and meanwhile, a high-frequency loudspeaker unit body which has uniform axle center with the mid-frequency loudspeaker unit body is arranged in a leading core column ring of the mid-frequency loudspeaker unit body. Middle and high pitches which are sent out by the mid-frequency and high-frequency loudspeaker unit bodies are respectively led to the center of a cone cavity of the low-frequency loudspeaker unit body through leading note pipes. The utility model has the advantages of simple structure, compact structure, clear full voice-frequency transmission, high sensitivity, small distortion and no magnetic leakage, and is a full voice-frequency coaxial loudspeaker which has comprehensive quality and is suitable for making various powers.
Description
The utility model relates to a kind of loud speaker, particularly coaxial full-band loudspeaker.
Chinese patent 95236091.8 discloses a kind of " the internal magnetization whole tone is coaxial loudspeaker frequently ", and structure is simpler, novel, can send perfectly whole tone frequency.But this loud speaker is an internal magnetization, thereby voice coil diameter is restricted, and magnet is little, and acoustic pressure is low, only is applicable to the small-power loud speaker; In addition, the unification of middle and high sound unit, tone color is clear inadequately.
The purpose of this utility model provides a kind of high, medium and low audio frequency and broadcasts clearly, highly sensitive, and distortion is little, and magnetic leakage free, simple in structure, the large and small power that is suitable for making, whole tone be coaxial loudspeaker frequently.
The technical scheme that realizes above-mentioned purpose is: by the basin frame and be connected and installed in sound basin in the basin frame, pressure ring, ripple props up sheet, permanent magnet, last magnetic conduction pole plate, the following magnetic conduction pole plate of band magnetic conductive core column circle and be positioned the magnetic conduction pole plate with magnetic conductive core column and enclose between voice coil loudspeaker voice coil formation woofer cell cube in the formed magnetic air gap, on the following magnetic conduction pole plate of woofer cell cube, connect concentric and the opposite mid frequency ludspeaker cell cube of magnetic pole, this mid frequency ludspeaker cell cube is then by magnetic conduction pole plate under the back of the body T shape that is connected with magnetic conductive core column's circle, the intermediate frequency magnet, last magnetic conduction pole plate, ball teleblem sheet, voice coil loudspeaker voice coil and bracket component thereof and leading note cover constitute, the middle pitch that the mid frequency ludspeaker unit sends is upwards by the voice guide hole on the magnetic conduction pole plate stem stem under the back of the body T shape, pelvic cavity through middle pitch sound guide tube guiding woofer cell cube, in the magnetic conductive core column of mid frequency ludspeaker cell cube circle, also installed concentric by the magnetic cover, the high frequency magnet, last magnetic conduction pole plate, ball teleblem sheet, high frequency voice coil loudspeaker voice coil and bracket component thereof, sealing cover draws the tweeter cell cube that take over to constitute in magnetic cover high pitch suitable for reading, and the high pitch that the tweeter cell cube produces is taken over and the high pitch sound guide tube is directed to the pelvic cavity center of woofer cell cube through drawing.
Accompanying drawing is a general structure schematic diagram of the present utility model.
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Woofer cell cube of the present utility model adopts tapered loud speaker, it by taper sound basin 1, pressure ring 2, ripple prop up sheet 3, voice coil loudspeaker voice coil 22 constitutes vibrational system; Constitute magnetic circuit system by the magnetic air gap that forms between mutual bonding all-in-one-piece permanent magnet 6, the following magnetic conduction pole plate 7 of going up magnetic conduction pole plate 5, band magnetic conductive core column circle and magnetic conductive core column's circle and the last magnetic conduction pole plate; The last magnetic conduction pole plate 5 of magnetic circuit system and the bottom of basin frame 4 riveted joint or be screwed is connected, and each parts of vibrational system are bonding mutually to be installed in the pelvic cavity of basin frame 4, and the lower end of voice coil loudspeaker voice coil 22 is positioned in the magnetic air gap of magnetic circuit system.The mid frequency ludspeaker cell cube that is connected with woofer cell cube concentric is to constitute the intermediate frequency magnetic circuit system by magnetic conduction pole plate on magnetic conduction pole plate 8, intermediate frequency magnet 9, the intermediate frequency under the back of the body T shape intermediate frequency that is connected with magnetic conductive core column circle 17 10 is bonding mutually; Intermediate frequency ball teleblem sheet, voice coil loudspeaker voice coil and 13 middle parts that are installed on magnetic conduction pole plate 10 on the intermediate frequency of bracket component, and voice coil loudspeaker voice coil is positioned on the intermediate frequency in the magnetic air gap between magnetic conduction pole plate 10 and the magnetic conductive core column circle 17; Be covered with the leading note aluminium cover 11 that is connected with magnetic conduction pole plate 10 on the intermediate frequency in ball teleblem sheet outside.The mid frequency ludspeaker cell cube is that the back of the body T shape center stem stem circle outer peripheral face by magnetic conduction pole plate 8 under the intermediate frequency is connected with threads engaged with magnetic conductive core column's circle inner peripheral surface of the following magnetic conduction pole plate 7 of woofer cell cube.Some voice guide holes 20 that the middle pitch that the mid frequency ludspeaker cell cube is sent is upwards offered on the back of the body T core post circle by magnetic conduction pole plate 8 under the intermediate frequency, the taper pelvic cavity of middle pitch sound guide tube 23 guiding woofer cell cubes through being connected with back of the body T core post circle.The tweeter cell cube is by magnetic cover 14, magnet 15, last magnetic conduction pole plate 16, ball teleblem sheet, high frequency voice coil loudspeaker voice coil and bracket component 18 and sealing cover draw in magnetic cover 14 high pitchs suitable for reading takes over 19 formations, and draw with its high pitch and to take over 19 periphery screw thread and be connected with the back of the body T core post circle inner peripheral surface threads engaged of the following magnetic conduction pole plate 8 of mid frequency ludspeaker cell cube, integral body is arranged in the magnetic conductive core column circle 17 of mid frequency ludspeaker cell cube, and with low, mid frequency ludspeaker cell cube concentric.The high pitch sound guide tube 21 that is opened on woofer cell cube taper pelvic cavity center that also is connected with suitable for reading that draws adapter 19 at high pitch.At last, be covered with Antimagnetic hood 12, last Zhoukou City of Antimagnetic hood 12 and the sealing-in mutually of basin frame 4 bottoms, leading note cover 11 bottom connections of its inner bottom surface and mid frequency ludspeaker cell cube in whole magnetic circuit system outside.In addition, the utility model has also adopted tri-frequency divider, is distributed to each basic, normal, high band loudspeaker cell cube behind the audio signal frequency division with input.
