Description

Microspeaker is with bodily form oscillating plate and preparation method thereof and Microspeaker
Technical field
The present invention relates to the Microspeaker oscillating plate, specifically, relate to Microspeaker that central portion at oscillating plate inserted rigid element with bodily form oscillating plate and preparation method thereof and the Microspeaker that possesses this oscillating plate.
Background technology
Usually, audio reproducing system can be divided into following type: horn loudspeaker; The Hi-Fi audio system that is used for this class of component system, and the system speaker that constitutes by audio amplifier, Squawker and the buzzer etc. that cover certain frequency range; Cover the general loud speaker of all frequency ranges by a unit; Has Microspeaker as the super light and slim size structure of microminiature video camera, walkman, PDA, notebook computer, mobile phone and IMT2000 communication terminal etc.; The receiver that is used for tracking exchage terminal etc.; A part is inserted the headset in the ear; And the buzzer that only receives the frequency of special frequency channel.
On the other hand, for PDA, notebook computer and IMT2000 communication terminal etc., the user is listening to the sound of reproduction with device position separated by a distance.Such portable equipment caters to the trend toward miniaturization of whole size and weight, dwindle its size, so its Microspeaker that adopts also needs to reduce constantly scale.
And these Microspeakers need acceptant music file along with the development of radio network technique and the structure of IMT2000, and will need high input/height output, reach the reproduction of high pitch to the wide frequency range of bass as arenas with loud speaker.
Fig. 1 is the exploded perspective view of an example that the Microspeaker of prior art is shown, and Fig. 2 is the cutaway view that the oscillating plate of Fig. 1 is shown.See figures.1.and.2 the explanation existing Microspeaker structure as follows.
Existing Microspeaker 100 comprises: the yoke 20 that is formed with groove 22 in central authorities; Magnet 30 with the inwall insertion separated by a certain interval of groove 22; Be installed on the plate 32 on the magnet; Be connected with the outside of yoke 20 and form the frame 10 of main body; Oscillating plate 50 by the supporting of the medial extremity of frame; Attached to the lower surface of oscillating plate and be clipped in yoke 20 and magnet 30 between the gap in and the voice coil loudspeaker voice coil 40 of up-down vibration; And baffle 70, its upper end at frame covers open upper portion, and is formed with at least one row's sound hole 72.And, formed the terminal 12 that external signal is provided to voice coil loudspeaker voice coil 40 in a side of frame 10.
In the Microspeaker of this structure, the voice coil loudspeaker voice coil 40 that receives external signal with and magnet 30 engage and 32 interactions such as grade of magnetized plate, thereby carry out up-down vibration, because this vibration, the oscillating plate 50 that is connected with voice coil loudspeaker voice coil top vibrates, thus by and extraneous air between pressure produce sound.
In addition, the structure of existing oscillating plate 50 comprises the central portion 50b of dome-shaped and forms annular edge part 50a to the extension of the central portion 50b outside and at its left and right sides.
Existing oscillating plate 50 is membranaceous formation with the macromolecular compound crimping of single blank normally, forms same material and same thickness thus.At this moment, therefore the oscillating plate 50 of single macromolecular compound for strengthening the intensity of central portion 50b, is made into arcuation according to the resonance frequency (Fs) that edge part 50a decides oscillating plate 50.That is, the central portion 50b of oscillating plate 50 is formed dome-shaped, thereby strengthen structural strength.But when constituting oscillating plate 50 by single film like this, produce the significantly problem of distortion of sound.
For addressing this is that, the method for making oscillating plate 50 according to Fig. 3 and step shown in Figure 4 has been proposed: make at the stacked light and high-intensity rigid element 102 of the central portion 111b of high molecular compound film 111.At this moment, for the chemical resistance and the moisture-proof of above-mentioned rigid element 102, at the stacked diaphragm 101,103 in the top and bottom of above-mentioned rigid element 102.
Promptly, as shown in Figure 3, rigid element 102 is layered between top diaphragm 101 and the bottom diaphragm 103, it is bonded to the central portion 111b of high molecular compound film 111, thus under the situation of the central portion 111b distortion that does not make oscillating plate 110, also can strengthen chemical resistance and moisture-proof, gain in strength simultaneously.
On the other hand, top diaphragm 101 and the bottom diaphragm 103 that is laminated in rigid element 102 in top and the bottom adopts thin thickness and light blank.For example, as the blank of top diaphragm 101 and bottom diaphragm 103, adopt metal stock or high molecular compound film sheet as aluminium flake.
Fig. 5 is the flow chart that the technology of making above-mentioned oscillating plate shown in Figure 4 is shown.
With reference to Fig. 5, to produce high molecular compound film 111 respectively and be bonded with after the rigid element 102 of diaphragm 101,103, bonding these two materials are finished oscillating plate 110.
More particularly, bonding layer high molecule compound film (S51), moulding (S52) is carried out stamping-out (blanking) (S53) afterwards, produces high molecular compound film 111 thus.
In addition, with rigid element 102 and top diaphragm 101 bonding (S54), again with bottom diaphragm 103 bonding (S55) afterwards, the rigid element 102 that is bonded with diaphragm 101,103 is carried out stamping-out (S56) produces rigid element 102.
To the high molecular compound film produced like this 111 and the rigid element 102 that is bonded with diaphragm 101,103 carry out bonding after, carry out drying (S57), finish oscillating plate 110 thus.
But, as shown in Figure 4, for the oscillating plate of producing like this 110, can't obtain the desirable chemical resistance and the problem of moisture-proof owing to the side open of rigid element 102 exists.
And, as described in Figure 5, owing to will therefore the shortcoming of complex manufacturing technology be arranged through repeatedly moulding, stamping-out, the bonding process such as stacked and bonding of the making of high molecular compound film, rigid element.
And, if then it being hardened or needing the extra time when dry, therefore there are long problem of Production Time in bonding polymer compound film and rigid element.
