Abstract
The utility model discloses a metal loudspeaker vibration diaphragm coated with a ceramic layer, which is mounted on a loudspeaker and comprises a metal vibration diaphragm base layer made of metal materials. The ceramic layer arranged on the surface of the metal vibration diaphragm base layer covers the whole surface of the vibration diaphragm, and the ceramic layer is an oxidized ceramic layer generated on the metal vibration diaphragm base layer by adopting micro-arc anodic oxidization technology. The metal loudspeaker vibration diaphragm correspondingly improves hardness and strength of the vibration diaphragm by adopting the micro-arc anodic oxidization technology to form the oxidized ceramic layer with high hardness on the surface of the metal vibration diaphragm, strengthens impact resistant performance of the vibration diaphragm, leads the surface of the vibration diaphragm to be difficult for oxidization, improves output sound quality of the vibration diaphragm, and enhances sound effect of the loudspeaker.
Description
Technical field
The utility model relates to the loudspeaker stereo equipment technical field, is specifically related to a kind of structure that is used for the metal vibrating diaphragm on the loudspeaker.
Background technology
The part that sound system tonequality is had the greatest impact is a loud speaker, 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.In order to address this problem, people have just invented the metal vibrating diaphragm, the metal vibrating diaphragm has the ratio spring rate of metal material and acoustic propagation velocity than paper material height, advantage such as humidity resistance is good, thermal conduction characteristic is good, that its tonequality has is penetrating, bright, characteristics clearly, therefore, the metal vibrating diaphragm has obtained application more and more widely.At present, the metal vibrating diaphragm mainly adopts aluminium, titanium, beryllium and corresponding alloy material, all is simple metal layer structure.The shortcoming of this structure is: its hardness and insufficient strength height, cause vibrating diaphragm easy deformation under specific circumstances, and shock-resistant ability is also limited, and the easily oxidation of vibrating diaphragm surface, thereby influences the normal audio of loudspeaker.
The utility model content
The technical problems to be solved in the utility model provides a kind of hardness height, intensity height, is difficult for the metal Loudspeaker diaphragm that is coated with ceramic layer of oxidation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of metal Loudspeaker diaphragm that is coated with ceramic layer, this vibrating diaphragm is installed on the loudspeaker, comprise with metal material and make metal vibrating diaphragm basic unit, it is characterized in that: the surface in metal vibrating diaphragm basic unit is provided with ceramic layer, ceramic layer covers on the whole surface of vibrating diaphragm, that is to say that tow sides have.
Further, described ceramic layer is that employing micro-arc anodic oxidation technology is created on the oxidation ceramic layer in the metal vibrating diaphragm basic unit.
The utility model generates the oxidation ceramic layer of one deck high rigidity by adopting the micro-arc anodic oxidation technology on the surface of metal vibrating diaphragm, thereby corresponding hardness and the intensity that has improved vibrating diaphragm, strengthened the shock resistance of vibrating diaphragm, it is oxidized that the vibrating diaphragm surface is difficult for, strengthen the output tonequality of vibrating diaphragm, improved the acoustics of loudspeaker.
Description of drawings
Fig. 1 is the horn integral structural representation;
Fig. 2 is an incision structural representation of the present utility model.
Among the figure, 1 is horn basin rack, and 2 is magnet, and 3 is washer, and 4 is voice coil loudspeaker voice coil, and 5 is vibrating diaphragm, and 51 is metal vibrating diaphragm basic unit, and 52 is ceramic layer, and 6 is dust cap, and 7 are flanging, and 8 is T iron, and 9 for playing ripple.
Embodiment
In the present embodiment, see figures.1.and.2, the described metal Loudspeaker diaphragm that is coated with ceramic layer belongs to parts of loudspeaker, whole loudspeaker comprise horn basin rack 1, magnet 2, T iron 8, washer 3, voice coil loudspeaker voice coil 4, play ripple 9, vibrating diaphragm 5 and dust cap 6, and the top of loudspeaker is flanging 7; Vibrating diaphragm 5 comprises with metal material makes metal vibrating diaphragm basic unit 51, is provided with ceramic layer 52 on the surface of metal vibrating diaphragm basic unit 51, and ceramic layer 52 covers on the whole surface of positive and negative of vibrating diaphragm 5.
Wherein ceramic layer 52 is that employing micro-arc anodic oxidation technology is created on the oxidation ceramic layer in the metal vibrating diaphragm basic unit 51.
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. metal Loudspeaker diaphragm that is coated with ceramic layer, this vibrating diaphragm is installed on the loudspeaker, comprises with metal material making metal vibrating diaphragm basic unit, it is characterized in that: the surface in metal vibrating diaphragm basic unit is provided with ceramic layer, and ceramic layer covers on the whole surface of vibrating diaphragm.
2. the metal Loudspeaker diaphragm that is coated with ceramic layer according to claim 1 is characterized in that: described ceramic layer is to be created on oxidation ceramic layer in the metal vibrating diaphragm basic unit by the micro-arc anodic oxidation technology.
