In the case of, other embodiments can be used and other changes can be made.It will be readily understood that such as substantially described and figure herein
Shown in each aspect of the present invention can arrange, replace, combine and design with a variety of different configurations, all these differences
Configuration all by the present invention clearly cover and become a part of the invention.
Fig. 1 is the exploded view of ultrathin loudspeaker according to an embodiment.Fig. 2 is ultrathin loudspeaker shown in FIG. 1
Cross-sectional view.
With reference to Fig. 1 and Fig. 2, ultrathin loudspeaker 10 includes diaphragm 101, washer 102, suspension link 103, sound in succession from top to bottom
Circle 104, frame 105, plate 106, magnet 107, U-shaped yoke 108 and net 109.
In some embodiments, diaphragm 101 includes dome 1011 and the circular part 1012 for surrounding dome 1011.
In some embodiments, washer 102 is arranged between diaphragm 101 and suspension link 103.Washer 102 is by insulation material
Material is made, such as rubber, plastics or paper.By using washer 102, suspension link 103 will not be hit around part 1012, so that surrounding
Part 1012 is unlikely to deform.
In some embodiments, suspension link 103 includes peripheral portion 1031, central part 1032 and by peripheral portion
1031 are connected to the coupling part 1033 of central part 1032.The upper surface of peripheral portion 1031 is attached to diaphragm 101, especially
Ground is attached to around part 1012.The lower surface of peripheral portion 1031 is attached to the upper surface of frame 105.It should be noted that peripheral portion
Upper and lower surfaces correspond respectively to the first surface and second surface of peripheral portion in the embodiment described in which.
In some embodiments, suspension link 103 may also include at least one extension (being not shown in Fig. 1 and Fig. 2),
At least one described extension is connect with the peripheral portion 1031 of suspension link 103, and the central part far from suspension link 103
1032.At least one extension can be bent for use as the pad of ultrathin loudspeaker 10, for introducing audio-source.With this side
Formula saves the space of independent pad.It therefore reduces the thickness of ultrathin loudspeaker 10.
Voice coil 104 is inserted into the hole limited by the central part 1032 of suspension link 103 and protrudes from the hole.Voice coil
104 upper surface is attached to diaphragm 101, particularly, is attached to dome 1011.In order to avoid Mechanical Contact and obtain relatively large
Power, voice coil 104 can be formed to have area as big as possible.When the insertion of voice coil 104 is by the central part of suspension link 103
When in 1032 holes limited, the central part 1032 of suspension link 1032 can be designed to the area for having as big as possible.Certainly, it answers
The size of voice coil and the size of central part are determined in the case where considering the size of entire loudspeaker 10.
When voice coil 104 pass through the upper surface in hole and peripheral portion 1031 limited by central part 1032 be attached to it is circular
When part 1012, position of the voice coil 104 in loudspeaker 10 can be kept well, and can be executed well vibrational system and be existed
Axial reciprocating in the loudspeaker be made of suspension link 103 and voice coil 104 is mobile.
In some embodiments, voice coil 104 does not include reel, to reduce the weight and height of ultrathin loudspeaker
Degree.
The plate 106 that diameter is less than the diameter of voice coil 104 is arranged in the hole limited by voice coil 104.The upper surface face of plate 106
To dome 1011.Magnet 107 is attached to the lower surface of plate 106.U-shaped yoke 108 is including central part 1081 and is located at central part
Two marginal portions 1082 of 1081 two sides, two of them marginal portion 1082 are higher than central part 1081, that is to say, that in
Center portion points 1081 is compared, and two marginal portions 1082 are closer to diaphragm 101.The central part 1081 of U-shaped yoke 108 is attached to magnet
107 lower surface.Two marginal portions 1082 of U-shaped yoke 108 are located at two gaps between frame 105 and voice coil 104
In.In some embodiments, plate 106, magnet 107 and U-shaped yoke 108 are inserted into as a whole in the hole limited by frame 105,
And the marginal portion 1082 of U-shaped yoke 108 is in the horizontal direction close to frame 105.
Damping screen 109 is arranged in below frame 105 and is attached to the lower surface of frame 105 and two sides of U-shaped yoke 108
Edge point 1082.Damping screen 109 can limit the Oscillation Amplitude of suspension link 103 and voice coil 104, and loudspeaker 10 is designed
At with relatively small thickness.In addition, relatively small Oscillation Amplitude may cause the low resonant frequency of ultrathin loudspeaker 10.It should infuse
Meaning, the upper and lower surfaces of frame correspond respectively to the first surface and second surface of frame in the embodiment described in which.
In some embodiments, the length of ultrathin loudspeaker 10 is smaller than 28mm, and the width of ultrathin loudspeaker 10 can be small
4mm is smaller than in the thickness of 16mm, ultrathin loudspeaker 10.
Viewed from above, in ultrathin loudspeaker, by using washer, suspension link will not be hit around part, therefore around part
It is unlikely to deform.Suspension link further includes at least one extension, at least one extension bending is for use as ultra-thin loudspeaking
The pad of device, for introducing audio-source.In this way, the space of independent pad is saved.Alternatively, since extension can
For use as pad, therefore independent pad can not needed.It therefore reduces the thickness of ultrathin loudspeaker.The center of suspension link
Part is designed to the area for having relatively large, so that the area of voice coil is relatively large, to avoid Mechanical Contact and obtain opposite
Big power.Due to voice coil, suspension link and around the connection structure of part, position of the voice coil in loudspeaker can be protected well
It holds, and it is mobile to execute axial reciprocating of the vibrational system in the loudspeaker being made of suspension link and voice coil well.Resistance
Buddhist nun's net can limit the Oscillation Amplitude of suspension link and voice coil, this makes loudspeaker have relatively small thickness and leads to loudspeaker
Low resonant frequency.
Fig. 3 be suspension link 103 shown in Fig. 1 and Fig. 2 for showing according to an embodiment stationary state and mobile shape
The schematic diagram of state.With reference to Fig. 3, when being in moving condition, the coupling part 1033 of suspension link 103 and central part 1032 with
