The utility model has the advantages that: improved frequency bandwidth, can make 40 hertz to 20,000 hertz full frequency band loud speaker; Owing to adopted radially magnetic circuit and " simulating radially magnetic circuit ", the magnetic line of force is more evenly distributed in magnetic gap, reduce harmonic distortion, help improving tonequality.
Below in conjunction with the nearly step explanation of accompanying drawing.
Fig. 1 broadband loudspeaker cut-away view;
Fig. 2 adds the broadband loudspeaker cut-away view of magnetic conductive tube;
Single magnet steel broadband loudspeaker cut-away view of Fig. 3 diametrical magnetization;
The high and low sound voice coil loudspeaker voice coil of Fig. 4 is cut apart use magnetic gap partial schematic diagram;
Two magnet steel broadband loudspeaker cut-away views of Fig. 5 diametrical magnetization.
Garden tubular magnet steel (2) and upper conduction magnetic board (3), following magnetic conductive board (1) by axial magnetized among Fig. 1 reach a field heart conducting magnetic column (5) the formation magnetic circuit system that joins with following magnetic conductive board, basin frame (11) is gone up the bass vibration component is installed, the bass vibration component comprises: the bass voice coil loudspeaker voice coil (4) that has skeleton connects bass vibrating diaphragm (10), and be provided with bass latch plate (9), link to each other with ring (12) between bass vibrating diaphragm and basin frame.The high pitch vibration component is installed at heart conducting magnetic column top, field, be that high pitch latch plate (7) is also referred to as the fixing heart conducting magnetic column on the scene top of centring disk, the outer tape splicing has the high pitch voice coil loudspeaker voice coil (8) of skeleton, and tweeters diaphragms (6) covers on the high pitch latch plate, and links to each other with high pitch voice coil loudspeaker voice coil upper end.The magnetic gap that forms between a shared upper conduction magnetic board of high and low sound voice coil loudspeaker voice coil and the heart conducting magnetic column.
Fig. 2 indicated on Fig. 1 basis in ring-like upper conduction magnetic board along setting up a magnetic conductive tube (13), its objective is that the magnetic line of force that makes by magnetic gap is more evenly distributed, make longer, wideer that magnetic gap does, be also referred to as " simulation diametrical magnetization " herein.
The input of single magnetic circuit coaxial loudspeaker high pitched signal can be divided into induction type and non-induction type.Non-induction type is the signal that will export in the audio signal output device and sends into high bass voice coil loudspeaker voice coil respectively.The closed-loop path of induction type for the high pitch voice coil loudspeaker voice coil is made the multi-turn wire-wound, form sensor transformer with a bass voice coil loudspeaker voice coil and a heart conducting magnetic column simultaneously, the audio signal full frequency band inputed to the bass voice coil loudspeaker voice coil, then on the sensed high pitch voice coil loudspeaker voice coil of high-frequency signal, the magnetic field force induced effect of high pitch tone currents of formation and promote the tweeters diaphragms pronunciation.
Fig. 3 is the broadband loudspeaker that a kind of magnet steel by diametrical magnetization (14) and E type magnetic conductor (17) form magnetic circuit system, E type magnetic conductor (17) is that reason annular magnetic conductive board is the E type with a vertical section of heart conducting magnetic column, saved upper conduction magnetic board, what magnetic gap can be done like this is very wide, long arbitrarily, the harmonic distortion when making electromagnetic interaction when the low frequency large amplitude further reduces.
Therefore can utilize the diametrical magnetization mode to make the coaxial loudhailer of single magnetic circuit shown in Figure 3, the shared magnetic gap of high and low voice coil loudspeaker voice coil; Also can make the loud speaker of single-tone circle list magnetic circuit.
Shown in Figure 4 is in single magnetic circuit coaxial loudspeaker, heart conducting magnetic column top, field can be made step-likely, staggers and places high and low voice coil loudspeaker voice coil, reaches and cuts apart the purpose of using magnetic gap.
Figure 5 shows that the double magnetic circuit coaxial loudspeaker also is a kind of form of broadband loudspeaker, magnet steel (15) is sleeved on magnet steel (16), forms double magnetic circuit, and the high pitch voice coil loudspeaker voice coil is interior, the bass voice coil loudspeaker voice coil outside, audio signal is imported respectively.
The diametrical magnetization of garden tubular magnet steel has following dual mode.
The first, garden tubular magnet steel radially is divided into tile-shaped magnet steel more than three, utilize traditional axial charging machine that each piece is distinguished radial magnetizing, watt shape magnet steel after will magnetizing again afterwards is assembled into the garden tubular, thereby reaches the radial magnetizing purpose.
Second, using special-purpose magnet charger that garden tubular magnet steel is carried out overall radial magnetizes, its magnet charger architectural feature is for adopting the closed magnetic circuit that magnetizes (traditional magnet charger is non-closed magnetic circuit), be equipped with two magnetized heads that can change (the magnet charger magnetic circuit part that magnetized head promptly joins with magnet steel), one of them magnetized head and magnet steel inner surface join, another magnetized head and magnet steel outer surface join, two magnetize coil respectively on two magnetized head fixed mounts, like this, form the closure magnetic circuit that magnetizes by magnet steel, magnetized head, outer conducting magnetic column.
