It is noted that the surrounding wall 10 can also be implemented as various shapes, such as triangular facet structure and rectangle Structure, the shape and structure of the surrounding wall 10 depend primarily on the shape feature of the loudspeaker 2.However, the surrounding wall 10 It is implemented as which kind of shape, the circular chamber 100 is respectively formed in the surrounding wall 10, for disposing the contour body 30.And the surrounding wall 10 is preferably implemented as globoidal structure, preferably to change the direction of propagation of the sound wave.
From the foregoing, it will be observed that the definition of surrounding wall 10 forms the circular chamber 100, wherein the contour body 30 is arranged on institute It states in chamber 100.When the eqalizing cricuit 1 is arranged on the loudspeaker 2, the contour body 30, which is arranged on, to be right against The position of vibration unit 50 on the loudspeaker 2, so that the loudspeaker 2 passes through the vibration due in response to audio signal After the sound wave that moving cell 50 is generated in a manner of agitating air can directly arrive at the contour body 30, because by the contour body 30 reflect and are changed radiation direction.The structure feature of the contour body 30 diagramatic content will be equipped with illustrated below, but ripe The people for knowing this technology should be understood that embodiment of the present invention is illustrative only, without limiting invention of the invention Spirit.
The contour body 30 is a stereochemical structure being made of cambered surface, i.e., the outer surface 301 of the described contour body 30 is arc Face design.In the first preferred embodiment of the present invention, the contour body 30 is implemented as a spherosome, but noticeable It is that the contour body 30 can also be implemented as oval ball, bullet header structure, or even asymmetric spherosome, and the present invention is in this side There is no restriction in face, and the first preferred embodiment of the present invention will be illustrated so that the contour body 30 is implemented as spherosome as an example, But the people for being familiar with this technology should be understood that embodiment of the present invention is illustrative only, of the invention without limiting Spirit.
When the contour body 30 is implemented as spherosome, a centre of sphere 31 is formed inside the contour body 30.The contour body 30 can be hollow spheres, be also possible to solid spherosome.In addition, the contour body 30 can be implemented as a variety of materials, than Such as plastic material, metal material, the mixture of composite material etc. or above-mentioned material nor affects on spirit of the invention. The material and internal structure of the i.e. described contour body 30 have no particular/special requirement.It is noted that the contour body 30 is with the ball 31 position of the heart is that boundary can be divided into a top half 32 and a bottom half 33 again, wherein the top half 32 and the bottom half Portion 33 collectively constitutes the contour body 30.Wherein the definition of top half 32 forms a top arc surface 321, and the bottom half 33 is fixed Justice forms a bottom arc surface 331, and the top arc surface 321 and bottom arc surface 331 are cambered surface design.By this method, When the contour body 30 is arranged above the loudspeaker 2, the bottom arc table of the bottom half 33 of the contour body 30 Face 331 towards the loudspeaker 2 the vibration unit 50, to make institute because agitating air for changing the vibration unit 50 The radiation direction of the sound wave of the generation of loudspeaker 2 is stated, meanwhile, the top half 32 of the contour body 30 can be used for driving The sound wave of external environment can be reduced in this way, or even avoid the sound wave of external environment for the loudspeaking The interference for the sound wave that device 2 generates, to guarantee the pure property of the audio of the electro-acoustic conversion device generation.
Specifically, the contour body 30 is implemented as the combination of the top half 32 and the bottom half 33, and institute It states and is respectively formed the top arc surface 321 and bottom arc surface 331 in top half 32 and the bottom half 33.With this side Formula, when the eqalizing cricuit 1 is arranged on the loudspeaker 2, the vibration of the loudspeaker 2 is arranged in the contour body 30 When the top of unit 50, the institute of the bottom arc surface 331 of the bottom half 33 of the contour body 30 towards the loudspeaker 2 Vibration unit 50 is stated, thus, the sound wave dissipated outward from the loudspeaker 2 arrives at the bottom on the contour body 30 Behind the bottom arc surface 331 of half portion 33, is reflected by the bottom arc surface 331 in the bottom half 33 and change propagation side To then depending from heart position and dissipate around.At the same time, the sound wave of external environment can also arrive at the contour body 30 The top arc surface 321 of the top half 32 changes and passes to be reflected by the top arc surface 321 on the top half 32 Direction is broadcast, and then the sound wave generated with the loudspeaker 2 is avoided to collide, then reduces, even is eliminated the electroacoustic Conversion equipment generates a possibility that noise.
It is noted that in some examples of the electro-acoustic conversion device of the invention, the institute of the contour body 30 It states top half 32 and the bottom half 33 can be integral structure, be also possible to split type structure.In addition, the top half 32 The radian on top arc surface 321 and the radian on bottom arc surface 331 of the bottom half 33 can be consistent, can also To be inconsistent.
Along straightline propagation in glitch-free situation, i.e., the described sound wave concentrates on the sound wave that the loudspeaker 2 issues The location mid-shaft of the loudspeaker 2 dissipates outward, and in this case, the sound wave that the loudspeaker 2 issues concentrates on institute On the location mid-shaft for stating loudspeaker 2.That is, the radiation direction and the loudspeaking of the sound wave that the loudspeaker 2 generates The direction of the vibration unit 50 of device 2 is consistent.However after the eqalizing cricuit 1 is arranged on the loudspeaker 2, from The sound wave exhaled on the loudspeaker 2 encounters the bottom arc surface in the bottom half 33 of the contour body 30 It is changed the direction of propagation because being reflected after 331, i.e., the described sound wave is reflected finally by bottom arc surface 331 to the contour body 30 surrounding diffusion.At this point, the radiation direction for the sound wave that the loudspeaker 2 generates and the vibration of the loudspeaker 2 The direction of unit 50 can be inconsistent.And at the same time, the sound wave of external environment encounters on the contour body 30 The top half 32 on top arc surface 321 after because being reflected be changed the direction of propagation, that is, external environment it is described Sound wave is finally dissipated to the surrounding of the contour body 30 after being reflected by the top arc surface 321.By this method, it can avoid external ring The sound wave in border arrives at the loudspeaker 2, and the sound wave generated with the loudspeaker 2 collides into noise, It ensure that the audio of the electro-acoustic conversion device, enjoyed so that the electro-acoustic conversion device can provide the more preferably sense of hearing for user By.
