The embodiment of the present invention provides a kind of vibrating diaphragm, speaker, sound chamber assembly and terminal, will carry out specifically respectively below Bright.
Embodiment one
The present embodiment provides a kind of vibrating diaphragm.This vibrating diaphragm can apply in the speaker of terminal.This terminal can be intelligence The equipment such as mobile phone, panel computer.
Coil-moving speaker is the most extensively applied, so that the audio electrical signal that terminal produces is converted into acoustic signals, Thus produce sound.The core of coil-moving speaker is voice coil loudspeaker voice coil and vibrating diaphragm.Voice coil loudspeaker voice coil is placed in magnetic field.When what terminal produced During audio electrical signal flowing through voice coil, voice coil loudspeaker voice coil can be produced vibration by the effect of magnetic field force (i.e. Lorentz force) in magnetic field.With The vibrating diaphragm that voice coil loudspeaker voice coil is connected consequently also produces vibration, and drives the air around vibrating diaphragm to produce vibration, thus produces sound.
The structural representation of the vibrating diaphragm that the embodiment of the present invention provides it is shown with reference to Fig. 1, Fig. 1.This vibrating diaphragm can apply to In speaker.Vibrating diaphragm 10 is thin film.The shape of vibrating diaphragm 10 is suitable with the shape of speaker, and the shape of vibrating diaphragm 10 can be circle Shape.
Vibrating diaphragm 10 includes main part 11, rib 12 and installation portion 13.Main part 11 is the border circular areas in the middle of vibrating diaphragm 10, The surface of main part 11 is continuous print flat surface.Rib 12 is the annular region of main part 11 periphery.At vibrating diaphragm 10 one On individual surface, on rib 12, along the circumferential direction spaced set has multiple reinforcement 121.Reinforcement 121 can increase vibrating diaphragm The rigidity of 10.The cross section of reinforcement 121 is the triangle or arc raised up along the surface of vibrating diaphragm 10.On rib 12, often Region between two reinforcements 121 is flat surface.Installation portion 13 is the marginal area of vibrating diaphragm 10, and with rib 12 even Connect.The surface of installation portion 13 is flat surface.Installation portion 13 is used for making vibrating diaphragm 10 be installed to other assemblies (such as, speaker) On.
Vibrating diaphragm 10 is whippy thin film, can be in the thickness direction up-down vibration of vibrating diaphragm.Vibrating diaphragm 10 passes through installation portion After 13 are installed to speaker, the main part 11 of vibrating diaphragm 10 and rib 12 are as vibration area.When vibrating diaphragm 10 vibrates, vibration area The air driving vibrating diaphragm both sides vibrates, therewith to produce sound.
Referring to figs. 2 and 3.The vibrating diaphragm 10 that Fig. 2 show in Fig. 1 is along the sectional view in A-A direction, and Fig. 3 is the vibrating diaphragm in Fig. 2 The close-up schematic view of part B.Multiple micro-hole it is formed with on vibrating diaphragm 10.Micro-hole can be only formed in the main body of vibrating diaphragm 10 In portion 11 or installation portion 12, it is also possible to be concurrently formed on main part 11 and rib 12, it is also possible to be concurrently formed at main part 11, on rib 12 and installation portion 13.In actual application, vibrating diaphragm 10 can be one-body molded by carbon nanomaterial.As it is shown on figure 3, Multiple micro-holes on vibrating diaphragm 10 are honeycomb texture.Each micro-hole in honeycomb texture is regular hexagon.Micro-hole is positive six Limit shape makes vibrating diaphragm 10 Stability Analysis of Structures, strengthens the rigidity of vibrating diaphragm 10 simultaneously.Multiple micro-hole is formed so that vibrating diaphragm 10 on vibrating diaphragm 10 Inside be hollow structure, it is possible to reduce vibrating diaphragm 10 density.Vibrating diaphragm 10 uses carbon nanomaterial to make, and carbon nanomaterial has Less density, it is thus possible to reduce the density of vibrating diaphragm 10 further.Therefore, use the vibrating diaphragm 10 that carbon nanomaterial is made, and And on vibrating diaphragm 10, form micro-hole, it is possible to effectively alleviate the quality of vibrating diaphragm 10.
The close-up schematic view of vibrating diaphragm of the prior art it is shown with reference to Fig. 4, Fig. 4.Vibrating diaphragm 20 of the prior art For solid construction.Vibrating diaphragm 20 is by the material such as PEN (PEN), PAR (poly-virtue fat), PEI (polymine) Make.
Common vibrating diaphragm uses the materials such as PEN, PAR, PEI to make, and the rigidity of vibrating diaphragm is little.During diaphragm oscillations, shake The Vibration Condition of film regional is inconsistent, thus easily produces diaphagras, causes the sound using the speaker of common vibrating diaphragm Arbitrarily downgrade reduction.
Vibrating diaphragm in the embodiment of the present invention, owing to have employed carbon nanomaterial, and is formed on vibrating diaphragm and multiple just has Hexagonal micro-hole so that the rigidity of the common vibrating diaphragm of ratio of rigidity of vibrating diaphragm is big.During diaphragm oscillations sounding, it is possible to have The generation of effect suppression diaphagras such that it is able to improve the sound pressure level of the speaker using this vibrating diaphragm.
Referring again to Fig. 1.The region shown in dotted line 15 in Fig. 1 be vibrating diaphragm 10 effectively vibrate area.Shown in dotted line 14 Region be the common vibrating diaphragm of same homalographic effectively vibrate area.Owing to the vibrating diaphragm in the embodiment of the present invention uses carbon nanomaterial Make, and formed on vibrating diaphragm and multiple there is orthohexagonal micro-hole, improve the rigidity of vibrating diaphragm, it is possible to suppression vibrating diaphragm Diaphagras.Therefore, in the case of vibrating diaphragm area equation, the vibrating diaphragm in the embodiment of the present invention has bigger than common vibrating diaphragm Effectively vibrate area.
Below equation is the computing formula of speaker sound pressure level:
P = B × L × ρ × S 4 π × 10 - 5 R × m
Wherein, P is the sound pressure level of speaker, and B is the magnetic induction in speaker, and L is the effective of speaker coil Length, ρ is atmospheric density, S be in speaker vibrating diaphragm effectively vibrate area, R is the DC impedance of coil, and m is speaker Oscillating mass.
Owing to being formed with multiple micro-hole on vibrating diaphragm, and vibrating diaphragm uses carbon nanomaterial to make, in the embodiment of the present invention Vibrating diaphragm than common vibrating diaphragm, there is less density, therefore the vibrating diaphragm with homalographic is less than the quality of common vibrating diaphragm, it is thus possible to Enough reduce the oscillating mass m of speaker.Simultaneously as the vibrating diaphragm in the embodiment of the present invention improves the rigidity of vibrating diaphragm, it is possible to have The diaphagras of effect suppression vibrating diaphragm, has bigger effectively vibration area S with the vibrating diaphragm of homalographic than common vibrating diaphragm.By above-mentioned public affairs Formula understands, and in the case of other parameter constants, reduces the oscillating mass m of speaker, increases effective vibration area S of vibrating diaphragm, Sound pressure level P of speaker can be increased.
From the foregoing, it will be observed that the vibrating diaphragm that the embodiment of the present invention provides, including in main part and rib, main part and rib Multiple micro-hole it is formed with at least one.The program provide vibrating diaphragm, due in the main part and rib of vibrating diaphragm extremely It is formed with multiple micro-hole, it is possible to reduce the density of vibrating diaphragm on few one, thus when vibrating diaphragm is applied to speaker, it is possible to reduce The oscillating mass of speaker, thus improve the sound pressure level of speaker.
