(playing the details of ripple)
Below, with reference to Fig. 4～Fig. 6, the details playing ripple 10 is illustrated. Fig. 4 is the profile playing ripple that embodiment 1 relates to. Fig. 5 and Fig. 6 is the profile of the major part playing ripple that embodiment 1 relates to.
In bullet ripple 10 as shown in Figure 4, par 10c and fluctuation portion 10d alternately has peak portion a1, a2, a3, a4, a5, a6 and valley b1, b2, b3, b4, b5 from inner circumferential side edge part 10a towards outer circumferential side edge part 10b. When speech coil framework 13 (with reference to Fig. 3) vibration on the fore-and-aft direction of speaker 100, peak portion a1～a6, valley b1～b5 and inner circumferential side edge part 10a stress. Inner circumferential side edge part 10a fixes due to the bonded portion 17 of its shape, therefore compared to peak portion a1～a6 and valley b1～b5, is hardly damaged.
As shown in Figure 5, specifically, par 10c is from the medial extremity a0 of inner circumferential side edge part 10a scope to a c1, this c1 is the point leaving side length r0 of the medial extremity a0 edge part 10b to outer peripheral side from inner circumferential side edge part 10a, and par 10c radially has length r0 bullet ripple 10. Fluctuation portion 10d is the scope the end d1 radially from a c1 to outer circumferential side edge part 10b side (with reference to Fig. 4) playing ripple 10. Here, some c1 is between valley b1 and peak portion a2. Thus, par 10c comprises peak portion a1 and valley b1, and fluctuation portion 10d comprises peak portion a2～a6 and valley b2～b5.
As shown in Figure 6, bullet ripple 10 has predetermined thickness t0, peak portion a1 and has height t1, and valley b1 has degree of depth t2. Specifically, the height t1 of peak portion a1 is equivalent to have the mutually level imaginary plane E2 distance to the downside first type surface playing ripple 10 from by supporting surface E1, by supporting surface E1 between the flange 12b of outer circumferential side edge part 10b and the second support 12. Additionally, the degree of depth t2 of valley b1 is equivalent to from imaginary plane E2 to the distance of the upside first type surface playing ripple 10. The height t1 of peak portion a1 is below the thickness t0 playing ripple 10. Additionally, the degree of depth t2 of valley b1 is below the thickness t0 playing ripple 10.
On the other hand, the highly preferred height t1 more than peak portion a1 of peak portion a2～a6, and the degree of depth of valley b2～b5 is preferably greater than the degree of depth t2 of valley b1. If additionally, the height of peak portion a2～a6 is more than the thickness t0 playing ripple 10, and the degree of depth of valley b2～b5 is more than the thickness t0 playing ripple 10, then the discrepancy in elevation of peak portion a1 and valley b1 is certainly less than the discrepancy in elevation between peak portion a2～a6 and valley b2～b5, it is thus preferred to.
Additionally, the radical length r0 of par 10c is preferably less than the 1/6 of the radical length Wd playing ripple 10. The radical length Wd (with reference to Fig. 2) playing ripple 10 is diametrically from the length of the inner circumferential side edge part 10a to outer circumferential side edge part 10b playing ripple 10. Additionally, the radical length r0 of par 10c is preferably less than the 1/12 of the radical length Wd playing ripple 10. On the other hand, the radical length r0 of par 10c can also be below 10mm. Radical length r0 for par 10c is less than the 1/12 of radical length Wd or less than the 1/6 of Wd and the relation that radical length r0 is below 10mm of par 10c that play ripple 10, will be described hereinafter.
For the ease of explanation, defining short transverse in playing ripple, the above-below direction played in ripple is equivalent to the fore-and-aft direction in speaker, specifically, play the upward direction in ripple and be equivalent to the forward direction in speaker, play the backward directions be in downward direction equivalent in speaker in ripple. Even if speaker towards change, the fore-and-aft direction in this speaker does not also change with the corresponding of above-below direction played in ripple. Such as, even if speaker is arranged down, the forward direction in speaker is also still equivalent to play the upward direction in ripple.
(action of speaker)
Below, the action of speaker is illustrated.
Refer again to Fig. 1, provide for making speaker 100 produce the signal of telecommunication of sound to voice coil loudspeaker voice coil 19. Then, voice coil loudspeaker voice coil 19 produces moment by magnetic produced by magnetic circuit device 18, and speech coil framework 13 is mobile to the fore-and-aft direction (being Z-direction here,-Z direction) of speaker 100 by the moment of voice coil loudspeaker voice coil 19. By the action of speech coil framework 13, vibrating diaphragm 15 vibrates, and this vibration is delivered to the medium around vibrating diaphragm 15, thus producing sound.
When the sound of speaker stops producing, play the speech coil framework 13 after ripple 10 keeps action and be returned to the precalculated position of magnetic circuit device 18. Thus, play ripple 10 and bear counteractive power produced by maintenance speech coil framework 13, produce stress in the inside playing ripple 10. If the voice output of speaker 100 is big, then the stress produced in the inside playing ripple 10 is also big.
But, owing to, in playing ripple 10, the height in the peak portion being in the par of inner circumferential side is equal to or less than the thickness t0 of annular slab, and the degree of depth of valley is equal to or less than the thickness t0 of annular slab, and the stress therefore produced in the inner circumferential side playing ripple 10 is little. Thus, even if speaker 100 exports big sound, though playing ripple 10 to stand big stress, it is also difficult to damage. It is difficult to damage additionally, due to play ripple 10, there is the exportable bigger sound of speaker 100 playing ripple 10.
(the analysis result of embodiment)
Below, with reference to Fig. 7～Fig. 9, the result that the embodiment relate to embodiment 1 and comparative example thereof are analyzed is described. Fig. 7 is the curve chart of the stress playing each position of ripple illustrating embodiment. Fig. 8 is the sectional stereogram playing ripple of comparative example. Fig. 9 is the curve chart of the stress playing each position of ripple illustrating comparative example.
In an embodiment, employ corresponding to the bullet ripple playing ripple 10. In a comparative example, the bullet ripple playing ripple 910 be equivalent to shown in Fig. 8 is employed. Play ripple 910 except par 910c and outer circumferential side edge part 910b, there is the structure identical with playing ripple 10. Par 910c has the discrepancy in elevation of peak portion 9a1 and valley 9b1, peak portion 9a1 and the valley 9b1 discrepancy in elevation equal to or more than the fluctuation portion 10d peak portion a2～6n comprised and valley b2～b5. Outer circumferential side edge part 910b is different from outer circumferential side edge part 10b, has upwardly extending sidewall on its edge, but outer circumferential side edge part 910b for stress described later almost without impact.
In embodiment and comparative example, analyze the stress produced at the position radially playing ripple. As experiment condition, use the multiple values in the scope of 0.1N～10N as to the input playing ripple inner peripheral portion. Illustrate the result of embodiment at Fig. 7, illustrate the result of comparative example at Fig. 9.
As it is shown in fig. 7, the stress value of peak portion a1～a6, valley b1～b5 is below 11MPa, it does not have significant difference.
As it is shown in figure 9, the stress value of peak portion 9a1 is very high compared with every other peak portion a2～a6, valley b2～b5. The stress value of valley 9b1 is height compared with the stress value of valley b1 (with reference to Fig. 7).
Embodiment is compared with comparative example, and the position of inner circumferential side, the such as stress value of peak portion a1, valley b1 etc. are little. Thus it is contemplated that: embodiment and comparative example being assembled in speaker and made speaker produce big sound respectively, embodiment is also also difficult to compared to comparative example damage. And, assemble the speaker of embodiment compared to the speaker assembling comparative example, exportable bigger sound.
(concrete example of speaker)

Wd=(10Ws-Wv)/2 ... (computing formula)
Additionally, the diameter Wv of voice coil loudspeaker voice coil determines substantially according to the bore Ws of speaker mostly. Such as, in the speaker that bore is 13cm, using diameter is the voice coil loudspeaker voice coil of 20mm. In the speaker that bore is 16cm, using diameter is the voice coil loudspeaker voice coil of 25～30mm. Additionally, in the speaker that bore is 25cm, using diameter is the voice coil loudspeaker voice coil of 45～50mm. Additionally, in the speaker that bore is 30cm, using diameter is the voice coil loudspeaker voice coil of 50～65mm.
Here, calculate Wd/6 and Wd/12 in the speaker of the bore with 13cm, 16cm, 25cm and 30cm, and show the result in table 1 below and table 2. In having the speaker of bore of 13cm, the diameter of spendable voice coil loudspeaker voice coil is a kind, therefore to be easy to illustrate, in Table 1, using its diameter as voice coil loudspeaker voice coil minimum diameter Wvmin.
[table 1]
[table 2]
As shown in Table 1 and Table 2, in having the speaker of bore of more than 13cm and below 30cm, bore is the Wd/6 in the speaker of below 16cm and bore has the value close to 10mm more than the Wd/12 in the speaker of 16cm. Thus, in having the speaker of bore of more than 13cm and below 30cm, the radical length r0 of par 10c is preferably below 10mm.
