Abstract
The utility model discloses a loudspeaker adopting a metal membrane, which comprises a loudspeaker frame, U iron, a magnet, a voice coil and a vibrating membrane, wherein the U iron is installed on the loudspeaker frame, the magnet is installed on a U-shaped cavity of the U iron, the voice coil is installed above the magnet, the vibrating membrane is installed on the voice coil, and the vibrating membrane is a metal vibrating membrane made of metal. In the loudspeaker, the metal vibrating membrane replaces the traditional vibrating membrane made of paper and the like, thus improving the rigidity of the vibrating membrane, the metal vibrating membrane can be processed very thin, thus reducing the weight of the loudspeaker, the heat conductivity is higher, so hat the transmission speed of sound can be improved, the sound of the loudspeaker is clearer, the sensitivity of the loudspeaker is improved, the distortion rate of the loudspeaker is lowered, the power of the loudspeaker is improved, and the loudspeaker has better property.
Description
Technical field
The utility model relates to the loudspeaker stereo equipment technical field, is specifically related to a kind of raising and leads device loudspeaker.
Background technology
The part that sound system tonequality is had the greatest impact is loud speaker (loudspeaker), and the critical component that influences loud speaker tonequality is vibrating diaphragm (being also referred to as bulging paper, sound film etc.), just as people's vocal cords.In the conventional art, vibrating diaphragm mainly adopts sheet material to make, and as the scraps of paper, plastic sheet etc., has developed the honeycomb and the foaming structure MULTILAYER COMPOSITE material that improve rigidity afterwards again.The advantage of this vibrating diaphragm is that rigidity is strong, and is not yielding.Shortcoming is that compound back weight lays particular stress on, and sensitivity reduces, and needing more, multiple current drives vibrating diaphragm.During the flaky material vibration, can produce torsional deformation as the shake scraps of paper or plastic sheet, send Pi crack noise, an and ringed line linking to each other with voice coil loudspeaker voice coil from the vibrating diaphragm root of the actuating force of cone loudspeaker, this is the most concentrated place of stress, when frequency raises deformation can take place, just as cool with scraps of paper fan, speed is quicker, and the place of holding will be twisted and be fractureed.
And loudspeaker horn for a long time major part all be to adopt vibrating diaphragm such as papery, because of the papery rigidity a little less than, it is less to make that loud speaker bears power, if increasing power output, just must increase bulging paper thickness, also increased simultaneously bulging paper weight, the sensitivity of Loudspeaker diaphragm (drum paper/sound film) will reduce.Especially now loudspeaker are main flow with compact, and as thin type horns such as television set speaker, earphone horn, computer loudspeaker, the vibrating diaphragm that more needs to have excellent properties promotes loudspeaker usefulness.Simultaneously also be fit to be used on other loudspeaker classes such as the home audio of the high-power super carrying of needs, commercial sound equipment, very excellent performance improvement is all arranged.
The utility model content
The technical problems to be solved in the utility model provides the loudspeaker horn of the employing metal vibrating diaphragm that a kind of rigidity is strong, in light weight, heat conductivity is good, acoustical quality is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of loudspeaker horn that adopts the metal vibrating diaphragm, comprise horn basin rack, U iron, magnet, voice coil loudspeaker voice coil and vibrating diaphragm, U iron is installed on the horn basin rack, magnet is installed in the U-shaped chamber of U iron, voice coil loudspeaker voice coil is installed in the magnet top, and vibrating diaphragm is installed on the voice coil loudspeaker voice coil, it is characterized in that: the metal vibrating diaphragm of described vibrating diaphragm for making with metal material.
Preferably, the material of described metal vibrating diaphragm is an aluminum metal, also can adopt other metal species such as copper, iron, magnesium, titanium, beryllium certainly, and perhaps their alloy material also can be done surface treatment or wait other processing with the compound use of other material on the metal vibrating diaphragm.
The utility model replaces the vibrating diaphragm of the materials such as papery of conventional loudspeakers loudspeaker by adopting the metal vibrating diaphragm, can improve the rigidity of vibrating diaphragm, the metal vibrating diaphragm can be accomplished very thin, therefore can alleviate loudspeaker weight again, and its heat conductivity is higher, can improve the conduction of velocity of sound, make speaker sound more clear, improve loudspeaker sensitivity, reduce the loudspeaker distortion rate, and can improve loudspeaker power, make loudspeaker have more performance.
Description of drawings
Fig. 1 is an incision structural representation of the present utility model.
Among the figure, 1 is horn basin rack, and 2 is U iron, and 3 is magnet, and 4 is voice coil loudspeaker voice coil, and 5 is vibrating diaphragm.
Embodiment
In the present embodiment, with reference to Fig. 1, the loudspeaker horn of described employing metal vibrating diaphragm, comprise horn basin rack 1, U iron 2, magnet 3, voice coil loudspeaker voice coil 4 and vibrating diaphragm 5, U iron 2 is installed on the horn basin rack 1, and magnet 3 is installed in the U-shaped chamber of U iron 2, and voice coil loudspeaker voice coil 4 is installed in magnet 3 tops, vibrating diaphragm 5 is installed on the voice coil loudspeaker voice coil 4, the metal vibrating diaphragm of described vibrating diaphragm 5 for making with metal material.
The material of described metal vibrating diaphragm is an aluminum metal, also can adopt other metal species such as copper, iron, magnesium, titanium, beryllium certainly, and perhaps their alloy material also can be done surface treatment or wait other processing with the compound use of other material on the metal vibrating diaphragm.
Below the utility model is described in detail, the above only is the preferred embodiment of the utility model, when not limiting the utility model practical range, be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
Claims (2)
1. loudspeaker horn that adopts the metal vibrating diaphragm, comprise horn basin rack, U iron, magnet, voice coil loudspeaker voice coil and vibrating diaphragm, U iron is installed on the horn basin rack, magnet is installed in the U-shaped chamber of U iron, voice coil loudspeaker voice coil is installed in the magnet top, vibrating diaphragm is installed on the voice coil loudspeaker voice coil, it is characterized in that: the metal vibrating diaphragm of described vibrating diaphragm for making with metal material.
