Abstract
A bowled reflective tweeter unit is characterized in that a hi-end is arranged on the bottom of bowl-shaped reflection bowl, and the surface of vibration membrane of the hi-end is similar to the bowl bottom. As a result, a high-frequency sound wave is directly reflected by the bowl bottom and diffused accordingly, which enhances the high-frequency sound wave and generates a large-range sound field, thereby preventing the occurrence of unbalance of music.
Description
Technical field
The utility model relates to the voice unit in a kind of home theater audio amplifier, especially for the bowl-shape reflective voice unit in the Hi-Fi sound-box.
Background technology
At present, the home theater audio amplifier or the Hi-Fi sound-box that are using, the loudspeaker of interior dress nearly all are to be directly installed on the Loudspeaker panel.Individual other also has loudspeaker is contained in the bugle and is installed on the panel.Or simply be contained in the audio amplifier top.But install in any case.The loudspeaker vibrating diaphragm all is that this has two drawbacks in the face of the audience, the one, and loudspeaker directive property is very narrow, just there is good effect on the top that the people must occupy isosceles triangle during listoning music, listen simultaneously as youngster individual, the people who then takes back or take over sounds the high pitch imbalance, makes us uncomfortable.The 2nd, loudspeaker is minimum at the power that the audio amplifier the inside receives, and sound is also minimum, and high pitch sounds not loud often fuzzy, lacks stereovision.So, want to hear hi-fi music for those, the sort of high parsing power, the well-bedded people who makes many people's while music appreciatings, the voice unit that present audio amplifier is used can not satisfy their requirement fully.
Summary of the invention
Have the directive property and the sensitivity of broad during for the playback of further raising loudspeaker unit, the utility model provides a kind of reverberation bowl of making by the shape of bowl, the bowl-shape reflective voice unit of bowl end dress high pitch head.
The concrete scheme that the utility model solves its technology is: at a shape such as the bowl-shape bowl end, by support, a high pitch head is installed, the vibrating diaphragm face of high pitch head is close with the bowl end, and the high frequency sound wave that the high pitch hair is given birth to is directly beaten on curved surface at the bottom of the bowl, reflection diffusion again.High frequency sound wave has obtained obvious enhancing.It is well arranged to dialyse, and a sound field has in a big way been arranged, and when making many people music appreciating, has eliminated uneven sense basically.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing one is a profile of the present utility model.
Accompanying drawing two is front views of the present utility model.
In accompanying drawing one, reverberation bowl (1), cone core (2), support (3), high pitch head (4).
Embodiment
In accompanying drawing one and two, reverberation bowl (1) can be made of any materials, but inner surface must be smooth and bright like a mirror, cone core (2), and support (3) and high pitch head (4) are glued, and behind the Installation and Debugging optimum distance, support (3) are bonded on the reverberation bowl (1) again.With fast tapping reverberation bowl (1) being fixed on Loudspeaker panel during use gets final product.
Claims (2)
1, a kind of bowl-shape reflective voice unit, by reverberation bowl (1), cone core (2), support (3) and high pitch head (4) are formed, and it is characterized in that: cone core (2), support (3), high pitch head (4) are arranged at reverberation bowl (1) bottom.
2, bowl-shape reflective voice unit according to claim 1 is characterized in that: the vibrating diaphragm surface of high pitch head (4) is relative with reverberation bowl (1) bowl end curved surface.
