Abstract
The utility model discloses a belt high pitch loudspeaker vibrating diaphragm, have the kapton film that prints the aluminium strip including upper bracket, lower carriage and one side, the kapton film sets up between upper bracket and lower carriage, the coating has transparent waterborne damped glue rete on the kapton film, the coating of waterborne damped glue rete has the back or the front of printing the aluminium strip on the kapton film. The utility model discloses the repercussions distortion of reducible belt high pitch vibrating diaphragm and the harmonic distortion of belt high pitch vibrating diaphragm, the control that makes the vibrating diaphragm motion receive magnetic circuit more reaches the more accurate level of the electric change of voice.
Description
Technical field
The utility model relates to electronics electroacoustic field, specifically a kind of ribbon high pitch loudspeaker vibrating diaphragm.
Background technology
Famous semiconductor science man WalterSchottky(Walter Schottky) with SiemensHalske(Siemens Ha Er Coase) nineteen twenty-three invented ribbon high pitch loudspeaker, owing to can not find the very strong magnet of magnetic at that time, the impedance of vibrating diaphragm and to bear power very little, cause inefficiency, so apply not extensive at that time.People utilized aluminium matter vibrating diaphragm and mated with more ferromagnetic material composition magnetic circuit and vibrational system afterwards, and obtain good efficiency and tonequality, ribbon high pitch loudspeaker starts to popularize gradually in high-end speakers systematic difference.
The current ribbon-type high-pitch vibrating diaphragm popularized has two kinds substantially: one be pure aluminum foil as vibrating diaphragm, the loud speaker of this kind of vibrating diaphragm makes and requires that high cost is high, uses face relative narrower; Another kind namely on the market most ribbon high pitch loudspeaker vibrating diaphragm adopt polyimides (PI) material (film of this material produced by Dupont be called " Kapton ") to do vibrating diaphragm substrate, substrate is printed aluminium foil circuit or copper foil circuit, and both synthesize ribbon high pitch loudspeaker vibrating diaphragm.The vibrating diaphragm of this material and technique is from performance, high frequency limit is not as the former, but due to the complex that it is polyimides and aluminium foil or Copper Foil, the distinctive shear wave sounding of metallics is made to obtain the suppression of certain degree owing to not being simple metal material on the one hand, on the other hand because the internal damping performance of polyimides (PI) material in vibration is better than the former, purer compared with the former in the tonequality of people's ear audible part range, too much harmonic wave is not had to cause sound coloration, so the former is good and cheap more welcome relatively.
Be no matter pure aluminum foil or in substrate, print the ribbon high pitch loudspeaker vibrating diaphragm of aluminium foil circuit or copper foil circuit with polyimides (PI) material (film of this material produced by Dupont be called " Kapton ") for vibrating diaphragm substrate, there is the defect that common: namely diaphragm surface is too smooth, self-damping performance is still short of, cause the composition of similar loud speaker sounding repercussions distortion or harmonic distortion too much, thus have impact on the fidelity of speaker system.
Repercussions distortion refers to not by the sounding phenomenon that magnetic circuit system controls, to ring according to seismic inertia without gong time hand " illiteracy sound " like beating gongs always and stop to inertia force that just to stop sound the same, vibration of membrane of shaking produces inertial oscillation acoustically also referred to as remained shock outside magnetic circuit control; Harmonic wave refers to overtone phenomenon, and namely the audio frequency of fundamental frequency 2 times is referred to as first overtone, and the audio frequency that fundamental frequency is 3 times is referred to as secondary overtone, by that analogy.No matter be repercussions or harmonic wave be all the sound be attached on original audio signal, sound unnecessary in audio signal, also be a kind of sound primary sound (signal original frequency) being carried out to sound coloration, these two kinds of sound wave compositions are all too much a kind of infringements to Hi-Fi audio signal playback quality, so also cry repercussions distortion and harmonic distortion.
Summary of the invention
The purpose of this utility model is to provide a kind of ribbon high pitch loudspeaker vibrating diaphragm, to solve the defect that existing ribbon high pitch loudspeaker vibrating diaphragm has repercussions distortion and harmonic distortion.
For achieving the above object, the utility model provides following technical scheme:
A kind of ribbon high pitch loudspeaker vibrating diaphragm, comprise upper bracket, lower carriage and the one side Kapton film with printing aluminium strip, described Kapton film is arranged between upper bracket and lower carriage, and described Kapton film is coated with clear aqueous damping glue rete.
As further program of the utility model: described aqueous damping adhesive film is coated in the back side with printing aluminium strip on Kapton film.
As the utility model further scheme: described aqueous damping adhesive film is coated in the front of Kapton film.
Compared with prior art, the beneficial effects of the utility model are: change because surface is too smooth and be short of the performance of internal damping, to increase the coefficient of friction of vibrating diaphragm in Air Coupling and viscosity, strengthen the air viscous force of diaphragm oscillations, thus reduce to a greater degree or reduce vibrating diaphragm repercussions and humorous wave interference, improve the acoustics fidelity performance of ribbon high pitch loudspeaker; The repercussions distortion of ribbon-type high-pitch vibrating diaphragm and the harmonic distortion of ribbon-type high-pitch vibrating diaphragm can be reduced, vibrating diaphragm is moved more by the control of magnetic circuit system, reaches electric change of voice level more accurately.
Accompanying drawing explanation
Fig. 1 is the ribbon-type high-pitch vibrating diaphragm cross-sectional view of existing polyimide film printing aluminium foil or copper foil circuit.
Fig. 2 is the cross-sectional view of ribbon high pitch loudspeaker vibrating diaphragm.
Fig. 3 is the structural representation of front surface coated in ribbon high pitch loudspeaker vibrating diaphragm.
Fig. 4 is the structural representation of backside coating in ribbon high pitch loudspeaker vibrating diaphragm.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-4, a kind of ribbon high pitch loudspeaker vibrating diaphragm, comprise upper bracket 1, lower carriage 2 and the one side Kapton film 3 with printing aluminium strip 4, described Kapton film 3 is arranged between upper bracket 1 and lower carriage 2, described Kapton film 3 is coated with clear aqueous damping glue rete 5, aqueous damping adhesive film 5 can be coated in the front of Kapton film 3, also can be coated in the back side with printing aluminium strip 4 on Kapton film 3.
No matter the utility model is pure aluminum foil or be vibrating diaphragm substrate with polyimides (PI) material and print the ribbon high pitch loudspeaker vibrating diaphragm of aluminium foil circuit or copper foil circuit in substrate all can at its backside coating one deck aqueous damping glued membrane, change its due to surface too smooth and be short of the performance of internal damping, to increase the coefficient of friction of vibrating diaphragm in Air Coupling and viscosity, strengthen the air viscous force of diaphragm oscillations, thus reduce to a greater degree or reduce vibrating diaphragm repercussions and humorous wave interference, improve the acoustics fidelity performance of ribbon high pitch loudspeaker.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
