Description
Technical field
What the present invention relates to is the relevant Mobyneb sound-producing device of notifying the user to send a telegram here with sound equipment or mode of vibration that carries on portable terminal computers (being designated hereinafter simply as machine) such as portable phone or small information communicating terminal.
Background technology
Above-mentioned portable terminal machine has incoming call for notifying the user, generally can switch and use buzz, melody song or do not have acoustic vibration, therefore need to carry simultaneously the sounding body that can send the sound that is similar to miniature loudspeaker and drive eccentric counterweight and rotate the vibrating body that produces vibrating effect by miniature motor.As this machine that carries sounding body and vibrating body simultaneously, its built-up time is longer, and is disadvantageous for the miniaturization and the lightweight of body.In recent years, also proposed a kind of scheme of multifunctional sounding body, promptly on a sounding body, possessed pronunciation simultaneously and vibrate two kinds of functions.
Fig. 8 is the exploded perspective view of the multifunctional sounding body of above-mentioned prior art, Fig. 9 is that multifunctional sounding body among Fig. 8 is from the observed view of diaphragm 7 sides, Figure 10 is the upward view after the shell with the multifunctional sounding body among Fig. 9 takes off, and Figure 11 is the sectional view when the B-B line cuts off of Fig. 9.
Multifunctional sounding body as shown in Figure 8 be engage by circular voice coil loudspeaker voice coil 8, with voice coil loudspeaker voice coil 8 single faces and passive diaphragm 7, constitute magnetic circuit 2 discoid magnetite 14, support this magnetite 14 the yoke that is the saucer shape 11, be positioned at the discoideus pole piece 12 of yoke 11 tops, on the both ends of the surface up and down of yoke 11, play the also resilient in the form of a ring suspension board 9 and 9 ', metal plate shell 15 of resiliency supported effect and these component-assembled circular basket 4 ' is together constituted.
Like this,, between the magnetic circuit 2 that constitutes by coil 8, magnetite 14 and pole piece 12, produced mutual magnetic attraction and repulsion, and begun vibration repeatedly by the electromagnetic force effect if the electric current of certain frequency is applied on the voice coil loudspeaker voice coil 8 from power supply terminal 16.At this moment, if power frequency reach a certain height---promptly be in the audio range, the vibration of the diaphragm 7 that is connected with coil 8 then can become greatly, can send the sound that buzz, melody sound, the tinkle of bells etc. can be heard thus.
On the other hand, because the intrinsic vibration coefficient of suspension board 9 and 9 ' is low, so do not vibrate substantially.But when in the lower frequency range of power frequency below audio frequency, 7 on diaphragm does not vibrate, and can not sound yet, and is fixed on suspension board 9 in the magnetic circuit 2 and 9 ' vibration this moment and will becomes big.So, begin vibration by magnetic circuit 2 and suspension board 9, the 9 ' mechanical vibrating system 10 that constitutes, and the vibrational energy of generation increased through the overall weight of vibrational system 10 thus.The vibration that produces is delivered to (not expression among the figure) on the machine that is equipped with multifunctional sounding body 3 ' by basket 4 ', to notify the user incoming call is arranged.Like this, a sounding body has just possessed pronunciation and has vibrated two kinds of functions.
On periphery wall, uniformly-spaced be provided with protruding eaves 6 to basket 4 ' internal face projection with about 120 degree as the yoke 11 ' of the mechanical vibrating system 10 of vibration generation source.This protruding eaves 6 both can be as the block that prevents the impact that yoke 11 ' and basket 4 ' are produced when bumping, and the weight that can guarantee yoke 11 ' again to a certain extent is so that the integral thickness attenuation of yoke 11 '.
As shown in figure 10, protruding eaves 6 is incorporated in the groove 17 of basket 4 ' internal face.This groove 17 is control and keeps the less way of basket 4 ' diameter, is again to prevent the radial shift that center line carried out of protruding eaves 6 with respect to basket 4 '.Displacement owing to protruding eaves 6 simultaneously prevents, also can prevent suspension board 9 and 9 ', reach the generation that coil 8 is out of shape.In addition, owing to be provided with groove 17, so breach 4 ' a and 4 ' b are necessary for embedding tab 9a, 9b, 9c and 9 ' a, 9 ' b, 9 ' c required minimal space are set, have two suspension boards 9 and 9 ' of difference of height up and down owing to being provided with simultaneously, so breach 4 ' a and 4 ' b also have difference of height.
In recent years, be tending towards improving, when incoming call being arranged, wish that more its vibratory output increases with the mode of vibration notice for the requirement of the sensitivity of call-in reporting.But, the structure of above-mentioned multifunction vibration body 3 ' such as Fig. 8 or shown in Figure 10, because 2 suspension boards 9 and 9 ' and protruding eaves 6 overlap, and clamp protruding eaves 6, so when mechanical vibrating system 10 up-down vibration, the addendum modification up and down of protruding eaves 6 can not exceed the allowed band of the elasticity displacement of suspension board 9 and 9 '.That is to say, because the up-down vibration of magnetic circuit 2 is controlled in certain scope by suspension board 9 and 9 ', so be difficult to produce big vibratory output.
In addition, as mentioned above, because protruding eaves 6 possesses the function of the block of resistance to impact, so need have certain intensity.Thus, need certain thickness and be difficult to make it attenuation, also limited the up-down vibration amount of magnetic circuit 2.
So,, the motion as Figure 12, Figure 13 and multifunctional sounding body 3 shown in Figure 14 has been arranged then in order to increase vibratory output.Figure 12 is the front view of multifunctional sounding body 3, and Figure 13 is the sectional drawing when the C-C section cuts off of the multifunctional sounding body 3 among Figure 12.The multifunctional sounding body 3 of Figure 12 with the main difference point of the multifunctional sounding body 3 ' of Fig. 8～Figure 11 is, not overlapped fitting together between protruding eaves 6 that about 120 degree in set every interval, magnetic circuit 2 outsides are provided with and 2 suspension boards 9 and 9 '.Because take this configuration mode,, see from the front 2 suspension boards 9 and 9 ' overlap each other to be in the same place so tab 9a, 9b, 9c and 9 ' a, 9 ' b, the 9 ' c of 2 suspension boards 9 and 9 ' (not shown) can be configured in same position.Like this,, and be provided with the embedded space 18 of protruding eaves 6,, also can make not overlay configuration of protruding eaves 6 and suspension board 9 and 9 ' so promptly use suspension board 9 and 9 ' that yoke 11 is given resiliency supported by the configuration up and down of suspension board 9 and 9 '.
On the contrary, because tab 9a, 9b, 9c and 9 ' a, 9 ' b, the 9 ' c of 2 suspension boards 9 and 9 ' are configured in same position, be on the inner peripheral surface of circular basket 4 ', for elasticity support 2 suspension boards 9 and 9 ' up and down, must between tab 9a, 9b, 9c and 9 ' a, 9 ' b, 9 ' c, establish pad 1 (as shown in figure 13).Owing on 1 suspension board 3 tabs are arranged, therefore need 3 pads.But, the situation of 3 pads is set respectively, not only improve manufacturing cost, and reduced packaging efficiency.Therefore, used the annular shim that 3 pads are connected in one.Shown in Figure 14 is the structural representation of annular shim 1 and magnetic circuit 2, and Figure 15 is the enlarged drawing of the keypoint part of protruding eaves 6 and pad 1.
When the machine that will be assembled with the multifunctional sounding body 3 among Figure 12 and Figure 13 when user mistake fell, multifunctional sounding body 3 will be subjected to the impact of external force.At this moment, if impulsive force is applied to projection direction (the arrow Y direction of Figure 14 of above-mentioned protruding eaves 6, i.e. 120 degree directions at interval) words on, because the front end and the gap d between the pad 1 10 minutes little (as shown in figure 15) of protruding eaves 6,6 effects that can play block of protruding eaves prevent the excessive displacement of mechanical vibrating system 10.
But, be that radially (all directions among Figure 14 beyond the Y direction) are impacted in actual use mostly, at this moment, because the gap d 2 between protruding eaves 6 and the pad 1 is bigger with respect to d1, so make the addendum modification of mechanical vibrating system 10 exceed outside the anticipation easily.Therefore, the impact that this addendum modification produces also makes suspension board 9 and 9 ' that big displacement takes place easily and then produces plastic deformation, the resonance characteristics deterioration that vibration is produced, and the parts of basket 4 inside are bumped mutually in operation and send fricative.
In the above-mentioned Mobyneb sounding body 3, owing on the inner peripheral surface of basket 4, need to set up new parts pad 1,, groove 17 is set on the inner peripheral surface of basket 4 ' so the multifunction vibration body 3 ' in can image pattern 8～Figure 11 is such.
