Abstract
The utility model relates to a coaxial loudspeaker, in particular to a single-magnet coaxial loudspeaker which comprises an upper magnetic plate and a lower magnetic plate, a high-voice voice coil, a low-voice voice coil, a high-voice vibrating basin, and a low-voice vibrating basin. The utility model is characterized in that only a magnet is arranged between the upper magnetic plate and the lower magnetic plate, and the axis position of the high-voice voice coil and the low-voice voice coil is provided with a central-plate conductive core-column. Compared with the prior art, the utility model adopts a single-magnet structure, and one magnet provides the energy needed by two magnetic roads, so the utility model has the advantages of simple structure, low production cost, and excellent stability of the high-voice magnetic road, and the periphery of the central-plate conductive core-column at the lower part of the high-voice voice coil can also be provided with a magnetic flux regulating ring in order to regulate the density of magnetic flux in the high-voice magnetic clearance.
Description
Technical field
The utility model relates to a kind of coaxial loudspeaker, especially a kind of single magnet coaxial loudspeaker.
Background technology
Traditional coaxial loudspeaker by two independently magnet be that bass magnet and the high pitch magnet that is placed in bass magnetic circuit middle part are formed separately independently magnetic circuit.High and low two voice coil loudspeaker voice coils are suspended from separately the magnetic gap and connect each self-vibration basin and servicing unit, be subjected to the restriction of high pitch voice coil loudspeaker voice coil because of high pitch magnet external diameter, though employing neodymium iron boron magnetic body, magnetic flux density is still lower in the high pitch magnetic circuit, simultaneously magnetic structure complexity, manufacturing cost are higher, relatively poor because of the neodymium iron boron thermal stability, be in high pitch and bass voice coil loudspeaker voice coil center simultaneously, so high pitch magnetic circuit thermal stability is bad.
Technology contents
The purpose of this utility model is to provide the coaxial loudspeaker of a kind of simple in structure, low cost of manufacture, high pitch magnetic circuit Heat stability is good, especially a kind of single magnet coaxial loudspeaker.
The utility model comprises upper and lower magnetic conduction pole plate, high pitch voice coil loudspeaker voice coil, bass voice coil loudspeaker voice coil, high pitch shake basin, bass shake basin, it is characterized in that being provided with and only being provided with between the upper and lower magnetic conduction pole plate magnet, be provided with center pole magnetic conductive core column at the axis part of high pitch voice coil loudspeaker voice coil and bass voice coil loudspeaker voice coil.
Above-mentioned magnet can be located at the periphery of center pole magnetic conductive core column, and center pole magnetic conductive core column is connected as a single entity with following magnetic conduction pole plate, also can be located between center pole magnetic conductive core column and the following magnetic conduction pole plate.
Above-mentioned center pole magnetic conductive core column is in a section of high pitch voice coil loudspeaker voice coil bottom and preferably is up-small and down-big vertebra shape.
Preferably be provided with the magnetic conduction spacer body between above-mentioned high pitch voice coil loudspeaker voice coil and the bass voice coil loudspeaker voice coil, the center pole magnetic conductive core column periphery of high pitch voice coil loudspeaker voice coil bottom preferably is provided with the magnetic flux adjustable ring.
Compared with prior art, the utility model adopts single magnet structure, provide two energy that magnetic circuit is required by a magnet, advantage with simple in structure, low cost of manufacture, high pitch magnetic circuit Heat stability is good, center pole magnetic conductive core column periphery in high pitch voice coil loudspeaker voice coil bottom also can be provided with the magnetic flux adjustable ring, to regulate the magnetic flux density in the high pitch magnetic gap.
