Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a wide sound field stereo set that resonant frequency point is low, includes front bezel 1, and the back mounted of front bezel 1 has medium loudspeaker 2, loudspeaker 3 and an installation section of thick bamboo 4, and the back mounted of an installation section of thick bamboo 4 has mounting panel 5, and the back fixedly connected with back plate 6 of mounting panel 5, the surface of mounting panel 5 are provided with first woofer 7 and second woofer 8.

In the present embodiment, when in use, the second woofer 8 and the first woofer 7 are connected in series to lower the resonance frequency point, and as a result, the effect of the low resonance frequency point of the subwoofer can be obtained by connecting the small woofers in series, which avoids the influence on the overall layout of the living room due to the impossibility of large space limitation, which is basically done in a narrow and long way, so that the speaker unit is made small, but the small resonance frequency point of the woofer becomes high, so that the effective frequency for reproduction is not low, which influences the effect of music reproduction, and the effects of the middle and high tones are smoother when in playing by the cooperation between the middle woofer 2 and the tweeter 3, thereby improving the playing effect, and the mounting of the mounting tube 4, the second woofer 8 and the first woofer 7 is facilitated by the mounting plate 5, the front plate 1 and the middle sound horn 2 play a role in protection.

Specifically, a side plate 9 is fixedly connected to the surface of the rear plate 6, and an electric box 10 is fixedly connected to the side edge of the side plate 9.
