Description
Technical field
The present invention relates to a kind of loudspeaker, especially one kind can with play wave part be fixed on loudspeaker monomer go out on sound face,
And by play wave part make monomer thinning and can stablize simultaneously vibrating diaphragm can balance vibration loadspeaker structure.
Background technique
Existing loadspeaker structure is a kind of electronic device for electronic signal being converted into voice signal, mainly in voice coil
Mutual exclusion can be generated after energization between magnet, similar piston type is formed and acts on, thus the vibrating diaphragm pushed in front of magnet of taking advantage of a situation, it will shake
Sound wave in front of film is radiate around, be will use the bullet wave of round in structure in addition to fix the voice coil, is due to playing wave
It is set between magnet and vibrating diaphragm, therefore loudspeaker just can not reduce in volume, also because of the limitation in volume, just can not answer
Light and short electronic product is stressed for many.
Technicalization at present electronic product (such as: slim TV, laptop, tablet computer, PDA, MP3 play
Device or mobile phone etc.), have the characteristics that frivolous characteristic or in order to meet whole type for ease of carrying, whole design
Specification, size production on it is all very small, the space in turn resulting in accommodating loudspeaker is also very limited, therefore many flat board speakings
Device just in response to and give birth to, and the panel speaker of this kind of smaller size is often frivolous in order to pursue, therefore can be by inside loudspeakers
Wave structure removal is played, so that overall structure is thinning, but the way so to restructure, in small-power output, due to vibrating diaphragm
Oscillation Amplitude is little, therefore does not allow to be also easy to produce distortion phenomenon；But in high-power output, the Oscillation Amplitude of the vibrating diaphragm is larger, this
When vibrating diaphragm will generate unbalanced vibration and shake, therefore but also the output of sound becomes highly unstable, therefore existing thin
Type loudspeaker is only able to satisfy low-power output efficiency and just generates corresponding limitation for being applied to high-power output.
Therefore, if a kind of loadspeaker structure can be provided, loudspeaker monomer is fixed on using a bullet wave part and is gone out on sound face, so that
When loudspeaker is driven sending vibration by high power, it can effectively be positioned by the bullet wave part and balance vibration vibration of membrane shape
State enables sound smoothly to export, and should be a best solution.
