Description

Common sound source sound box structure

Technical Field

The utility model relates to a stereo set product technology field especially relates to a better stereo set of acoustic effect.

Background

Audio products are electronic and electrical devices widely used by people, and the conventional audio products are usually formed by separately mounting high-low sound speakers on the same surface. Although the structure is simple in design and convenient to install, the sound positioning often has deviation to cause phase distortion, and the sound connection is not natural enough. There are also tweeters that are mounted coaxially on the back of the woofer (the frequency response curve is shown in fig. 6) or inside the woofer (the frequency response curve is shown in fig. 7), but these two mounting methods require a high level for the woofer, and require a large enough hole in the center post of the T-iron (rear cleat) of the woofer, otherwise the tweeter cannot be mounted or is extremely poor in effect. In addition, the sound wave output of the conventional high and low sound coaxial sound is transmitted through the whole bass channel, and when the sound wave output passes through the woofer, the sound wave output generates reflection interference with a T iron (rear splint) through hole and a cone (drum paper) of the woofer, and finally, the actually tested high sound curve has very large fluctuation, so that the distortion is obvious, as shown in fig. 4 and 5, the peak-valley fall of a high frequency part is large, and the curve is distorted. And due to the influence of the structure, the adjustment and calibration of the later stage sound box are very difficult.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to prior art's shortcoming, provide a simple structure, easily design, simple to operate, timing are easy, the better common sound source sound structure of acoustic effect.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a common sound source sound structure, including box, loudspeaker and frequency divider subassembly, loudspeaker are including woofer and tweeter, and woofer and frequency divider subassembly are installed respectively in the box its characterized in that: loudspeaker and woofer coaxial arrangement, loudspeaker install in woofer, and loudspeaker's front portion stretches out and protrusion one section in woofer's the place ahead from woofer's center.

Preferably, the tweeter is locked in the woofer by a screw.

Furthermore, a screw hole is formed in the center of a U-shaped iron of the tweeter, a fixing piece is inserted into the tail end of the tweeter, a supporting piece is embedded into the front end of the fixing piece, and the rear section of the U-shaped iron is embedded and fixed in the supporting piece; and the screw rod sequentially penetrates through the fixing piece and the supporting piece and is screwed into the screw hole of the U-shaped iron, so that the high pitch loudspeaker and the low pitch loudspeaker are locked and fixed. The fixing piece and the supporting piece are matched to install the high pitch loudspeaker, so that the mutual transmission of vibration of the high pitch loudspeaker and the low pitch loudspeaker during working can be basically eliminated.

Furthermore, the fixing piece is of a T-shaped structure, and the outer end of the fixing piece is clamped on the tail end face of the woofer; the outer end face of the fixing piece is provided with a tripod to clamp the fixing piece and buffer part of vibration, and the screw penetrates through the tripod and penetrates into the fixing piece.

Or the tweeter is fixed in the woofer through glue.

Or the tweeter is clamped and fixed with the woofer through a buckle structure. Other fixing modes also have the same or similar effect, and the key point is that the high-low sound loudspeakers work on the same axis at the same time, so that the effect of sharing the sound source is achieved.

The utility model discloses an install loudspeaker in woofer and stretch out in woofer preceding, so low to woofer's requirement, regardless of woofer's bore size all can install to be favorable to the design work. The high pitch output of the sound equipment is actually the high pitch itself when in work, and the high pitch does not pass through the low pitch, so the low pitch horn has little influence on the high pitch, the sound fidelity is higher, the sound image is positioned perfectly, the music resolution is higher, the sound is more sweet, real and natural, and the adjustment and calibration on the sound box at the later stage are easier, thereby further improving the sound quality of the sound equipment and improving the quality of the sound equipment product.

Detailed Description

In this embodiment, referring to fig. 1, 2 and 3, the common sound source sound structure includes a box 1, a speaker and a frequency divider assembly, the speaker includes a woofer 2 and a tweeter 3, and the woofer 2 and the frequency divider assembly are respectively installed in the box 1; loudspeaker 3 and woofer 2 coaxial arrangement, loudspeaker 3 installs in woofer 2, and loudspeaker 3's front portion stretches out and protrusion one section in woofer 2's the place ahead from woofer 2's center, makes the high pitch output actually be the high pitch itself promptly like this, need not pass through woofer 2, high, woofer mutual independence work, mutually noninterfere, so woofer 2 is minimum to the influence of high pitch.

Referring to fig. 4 and 5, the tweeter 3 is locked in the woofer 2 by a screw 4.

A screw hole is arranged in the center of a U-shaped iron 5 of the tweeter 3, a fixing piece 7 is inserted at the tail end of the woofer 2, a supporting piece 6 is embedded at the front end of the fixing piece 7, and the rear section of the U-shaped iron 5 is embedded and fixed in the supporting piece 6; the screw rod 4 is threaded into the screw hole of the U-shaped iron 5 through the fixing piece 7 and the supporting piece 6 in sequence, so that the tweeter 3 and the woofer 2 are locked and fixed. The fixing piece 7 is matched with the supporting piece 6 to install the tweeter 3, so that the mutual transmission of vibration of the tweeter 3 and the woofer 2 during working can be basically eliminated.

The fixing piece 7 is of a T-shaped structure, and the outer end of the fixing piece is clamped on the tail end face of the woofer 2; a tripod 8 is provided on an outer end surface of the fixing member 7 to clamp the fixing member 7 and to buffer a part of vibration, and the screw rod 4 penetrates into the fixing member through the tripod 8.

Of course, the tweeter 3 may be fixed in the woofer 2 by an adhesive, or the tweeter 3 may be fixed in a snap-fit manner with the woofer 2 (these two ways are not shown). Other fixing modes also have the same or similar effect, and the key point is that the high-low sound loudspeakers work on the same axis at the same time, so that the effect of sharing the sound source is achieved.
