Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

1-5, Including installing the tweeter 2 and the horn support 1 on the stereo set, horn support 1 sets up the play sound side at tweeter 2, is equipped with the leading tone passageway 104 that is linked together with tweeter 2 play sound side in the horn support 1, and leading tone passageway 104 becomes the passageway of leading sound radiation from inside to outside gradually, forms the sound wave frequency with this kind of structure when being applied to the stereo set with tweeter 2 during operation, outwards vocalizes through the guide of horn support 1, can let the tweeter acoustic pressure promote 2 ~ 3dB after above combination, improves the directionality to promote the tone quality of high pitch.
