Radial R.The length direction of side through hole 112d ' is also approximately perpendicular to the radial R of circular frame 112 '.It is set similar to frame 112
Meter, the gross area of multiple side through hole 112c ' of frame 112 ' are less than the gross area of multiple side through hole 112d '.
Referring to FIG. 6, the performance for the loudspeaker total harmonic distortion of different embodiments of the invention compares figure.Institute in detail in this figure
The loudspeaker embodiment compared, respectively includes tri- kinds of frames of type A, B, C, and schema is illustrated in figure respectively.The frame of type A
High pitch tone chamber in side through hole (the 4X2 through-hole) gross area be less than bass tone chamber in side through hole (6X2 through-hole) gross area.Type
(3X2 larger less than side through hole in bass tone chamber for side through hole (3X2 compared with small through hole) gross area in the high pitch tone chamber of the frame of B
Through-hole) gross area.The side through hole gross area is equal to the side through hole gross area in bass tone chamber in the high pitch tone chamber of the frame of Type C.Ginseng
It can according to loudspeaker total harmonic distortion corresponding to type A, B, C (Total Harmonic Distortion, THD) ratio curve
Know, between frequency 30Hz to 200Hz, for the total harmonic distortion ratio of loudspeaker output audio, the loudspeaker of type A is small
In the loudspeaker of type B, and the loudspeaker of type B is less than the loudspeaker of Type C.Specifically, in frequency 100Hz, type A
Total harmonic distortion ratio be 4.17%, the total harmonic distortion ratio of type B is 5.60%, the total harmonic distortion ratio of Type C
It is 6.53%.In frequency 200Hz, the total harmonic distortion ratio of type A is 0.66%, the total harmonic distortion ratio of type B is
0.87%, the total harmonic distortion ratio of Type C is 1.43%.The lower expression loudspeaker of total harmonic distortion ratio can be more true defeated
Audio out.In addition, the strip side through hole on the frame of type A, B also facilitates to lower total harmonic distortion ratio.
In conclusion loadspeaker structure of the invention, by range partition wall to separate out high pitch tone chamber and bass tone chamber,
And the high and low sound for generating vibrating membrane has tone chamber independent and around channel to avoid the high and low mixture of tones, separately cooperates frame
The shape of the side through hole of frame designs and the gross area difference in high and low sound tone chamber, and then lowers total harmonic distortion ratio, is promoted
The sound quality of high and low sound output.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
