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.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

The embodiment of the utility model provides a loudspeaker, including loudspeaker monomer 1, cavity 2 and reflection awl 3, during cavity 2 was located to loudspeaker monomer 1, reflection awl 3 was located the below of cavity 2, as description attached drawing 1 and attached drawing 2 show.

The cavity 2 can be set to semi-closed form, and the bottom of cavity 2 is equipped with the through-hole, can adopt fasteners such as bolt to link to each other between loudspeaker monomer 1 and the cavity 2, and the sound that loudspeaker monomer 1 sent can spread out outside cavity 2 through the through-hole of cavity 2. A certain gap is formed between the reflecting cone 3 and the cavity 2, and the reflecting cone 3 and the cavity 2 can be connected by using a component such as a bolt.

The sound that loudspeaker monomer 1 sent can make the sound spread to the bottom outside of cavity 2 under the effect of reflection awl 3 behind the outside that cavity 2 was spread to the through-hole of cavity 2, has also changed the propagation direction of sound, has realized the side play sound of cavity 2. It can be seen that the reflecting cone 3 has two functions, one is to change the propagation direction of the sound, and the other is to guide the sound having changed direction to the outside of the bottom of the cavity 2.

As can be seen from fig. 2 in the specification, the sound is transmitted to the bottom outside of the cavity 2 by means of the combined action of the reflection cone 3 and the cavity 2, and the cavity 2 and the reflection cone 3 both form a sound transmission path, that is, a structure similar to a pipeline along which the sound can be transmitted.

The embodiment of the utility model provides a speaker still includes cavity 21, and cavity 21 has gap 22, and cavity 21 sets up in one side of the propagation path of the sound that loudspeaker unit 1 sent, and cavity 21 is close to the side of the propagation path of the sound that loudspeaker unit 1 sent in the side is located to gap 22.

From the above, it can be seen that the cavity 21 is arranged on one side of the pipe-like structure (propagation path), and since the pipe-like structure comprises the cavity 2 and the reflection cone 3, the cavity 21 can in principle alternatively be arranged on the cavity 2 and the reflection cone 3, and of course, the cavity 21 does not have to be connected to the cavity 2 and the reflection cone 3, and the cavity 21 can exist as a separate component.

Obviously, the cavity 21 should not obstruct the propagation path, and the cavity 21 may be considered as a part of the propagation path, in that the propagation direction of the sound should not be substantially changed.

It can be seen that the cavity 21 thus provided can be regarded as a helmholtz resonator, i.e. a resonant muffler, and sound is propagated along a structure similar to a pipeline in the process, due to the existence of the resonant muffler, so that sound waves of a specific frequency band are suppressed, and then the sound quality is improved, and the acoustic effect is optimized.
