Abstract
The utility model relates to a 360-degree omnidirectional ultra high frequency loudspeaker, belonging to the field of a sound amplifying system. The loudspeaker is composed of an iron core, an acoustic expander, a metal foil vibrating diaphragm, a permanent magnet, a magnetic conduction board, a screw rod and a bottom cover. The acoustic expander is arranged on the bottom cover; the permanent magnet and the magnetic conduction board surround the outer end surface of the iron core; the metal foil vibrating diaphragm surrounds the outer end surfaces of the permanent magnet and the magnetic conduction board; a plurality of conductive copper sheets are arranged on the metal foil vibrating diaphragm; a 360-degree circular metal foil is the vibrating diaphragm; a conductive coil is formed by the plurality of conductive copper sheets in a 360-degree encircled manner. With simple structure, the loudspeaker realizes that sound has no directive property in the horizontal direction, thus leading the sound to be spread to any position in the entire space, leading the highest frequency to reach an ultra high frequency band of 100kHz and meeting the requirements of different users.
Description
Technical field
The comprehensive hyperfrequency loud speaker of the utility model 360 degree belongs to the public address system field, particularly relates to a kind of loud speaker.
Background technology
The tweeter that uses all is outwards outwards to expand with 180 degree planes with the point sound source pronunciation now, because there is directive property in sound, frequency is high more, and directive property is strong more, and the coverage rate of the strong more sound of directive property is just low more.Common tweeter pronounces with point sound source, the intensity of sound of sending is weakened gradually by middle alignment both sides, so the position of audition the best is on the horizontal direction linear position of dead ahead, sound weakens to both sides, both sides and back to loud speaker be can't hear sound fully, can only be the highest in vertical direction with the outwards expansion of 90 degree, sound skewness and sound area coverage are little, exist the significant deficiency that sound be can't hear in loud speaker backside space position.Common tweeter is owing to be subjected to the limitation of diaphragm materials characteristics design organization plan, and highest frequency can only be gone up 20kHz.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of non-directive of sound in the horizontal direction is provided, and sound is evenly distributed big with the sound area coverage, and highest frequency can be gone up the comprehensive hyperfrequency loud speaker of 360 degree of 100kHz.
The purpose of this utility model reaches by following measure, it is by iron core, the acoustics expander, the metal forming vibrating diaphragm, permanent magnet, magnetic conductive board, screw rod, bottom is formed, the acoustics expander is installed on bottom, screw rod fixed bottom cover and acoustics expander, on the outer face of iron core, be arranged at intervals with permanent magnet and magnetic conductive board, permanent magnet and magnetic conductive board are looped around on the outer face unshakable in one's determination, on the outer face of permanent magnet and magnetic conductive board around the metal forming vibrating diaphragm, the metal forming vibrating diaphragm is provided with several conductive copper sheets, 360 degree endless metal paper tinsels are as vibrating diaphragm, several conductive copper sheet 360 degree annulars form conductive coil, the annular vibrating diaphragm of 360 degree is put into the 360 degree toroidal magnetic fields of forming by permanent magnet and magnetic conductive board, conductive copper sheet conductor conducting direction on endless metal paper tinsel vibrating diaphragm just forms perpendicular quadrature with 360 degree toroidal magnetic field magnetic line of force directions, when conductive copper sheet is switched on, the stressed traction metal forming of conductive copper sheet vibrating diaphragm vibration pronunciation.The comprehensive hyperfrequency loud speaker utilization of 360 degree Fu Laiming Left Hand Rule, for the conductor dbus that becomes to intersect vertically with magnetic field with electric current, make conductor cause motion bearing strength with the right angle orientation of magnetic field and electric current, adopt 360 degree endless metal paper tinsel vibrating diaphragms, several conductive copper sheets form conductive coil as conductor loop on the metal forming vibrating diaphragm, 360 degree endless metal paper tinsel vibrating diaphragms are put into the 360 degree toroidal magnetic fields of being made up of strong magnetic permanent magnet and magnetic conductive board, the conductive copper sheet conducting direction just forms perpendicular quadrature with 360 degree toroidal magnetic field magnetic line of force directions like this, because vibrating diaphragm and magnetic field all are 360 degree annulars, so on the metal forming vibrating diaphragm 360 degree ring surfaces all is evenly to pronounce, the acoustics expander is outwards propagated the sound that sends on the 360 degree endless metal paper tinsel vibrating diaphragms along the transaudient sound of vibrating diaphragm above-below direction 180 degree.
Metal forming vibrating diaphragm of the present utility model adopts aluminium foil, 0.1 millimeter of thickness.
Acoustics expander of the present utility model adopts 360 degree annulars.Two acoustics expanders snap together.
Conductive copper sheet of the present utility model adopts and is plated on the aluminium foil vibrating diaphragm, reduced with the weight of stent support conductive coil support and conductive coil has been fixed on the weight of glue on the vibrating diaphragm, the vibrating body weight that vibrating diaphragm and conductive coil are formed is lighter, vibrating body weight is light more, and it is high more that the high frequency frequency can reach.
Magnetic conductive board of the present utility model is an annular, and permanent magnet is an annular, and permanent magnet and magnetic conductive board are stacked to be placed on the acoustics expander, and iron core is placed in permanent magnet and the magnetic conductive board, and the indentation of the stacked interval of permanent magnet and magnetic conductive board is placed, and forms concavo-convex at interval.
The utility model is simple in structure, realized sound non-directive in the horizontal direction, solved the sound skewness that common loudspeaker causes because of the sound directivity problem and the sound area coverage is little and the significant deficiency of sound be can't hear in loudspeaker backside space position, make the optional position in whole space can both have sound to propagate into, highest frequency can be gone up the hyper band of 100kHz, satisfies requirements of different users.
