Fig. 1 is a schematic diagram of the structure of a bass speaker provided by an embodiment of the utility model. Fig. 2 is a schematic diagram of the cross-sectional structure of a bass speaker provided by an embodiment of the utility model.

As shown in combination with FIG. 1 and FIG. 2 , an embodiment of the present application provides a bass speaker 100, which may include a housing assembly 10 and at least one speaker group 20 located in the housing assembly 10. The speaker group 20 includes a first speaker 21, a second speaker 22, and a third speaker 23, and the first speaker 21, the second speaker 22, and the third speaker 23 all include a front side of a radiation basin and a back side of a radiation basin that are arranged oppositely.

It should be noted that the front of the radiation basin refers to the concave surface of the radiation basin of the speaker. The back of the radiation basin refers to the end facing the speaker where the magnet is set, that is, the convex surface of the radiation basin. When the radiation basin vibrates, both the front and back of the radiation basin vibrate in the same direction.

It should be noted that in the embodiments of the present application, "relative" refers to relative in a broad sense, and is not limited to frontal relative arrangement. "Towards" refers to the direction in a broad sense, and is not limited to the facing direction.

Exemplarily, one, two, three, four or more speaker groups 20 may be disposed in the housing assembly 10 . In the implementation of the present application, the number of the speaker groups 20 is not further limited.

In the first direction, the radiation basin front 211 of the first speaker and the radiation basin front 221 of the second speaker are relatively spaced apart and sealedly connected to the shell assembly 10 respectively, so as to form a first sealed cavity 113 between the radiation basin front 211 of the first speaker and the radiation basin front 221 of the second speaker.

The second speaker 22 and the third speaker 23 are spaced apart along the second direction, and the second direction is perpendicular to the first direction. The front face 231 of the radiation basin of the third speaker is sealed and connected to the housing assembly 10, and a second sealed cavity 114 is formed between the second speaker 22 and the third speaker 23. The front face 231 of the radiation basin of the third speaker faces away from the front face 221 of the radiation basin of the second speaker, and the front face 231 of the radiation basin of the third speaker is connected to the outside of the housing assembly 10. The back face 222 of the radiation basin of the second speaker and the back face 232 of the radiation basin of the third speaker are both located in the second sealed cavity 114.

The bass speaker 100 in the embodiment of the present application is provided with a housing assembly 10, and a speaker group 20 is provided between the housing assembly 10, so that the housing assembly 10 can protect the speaker group 20 and prevent the speaker group 20 from being damaged. By providing the speaker group 20 to include a first speaker 21, a second speaker 22 and a third speaker 23, and the first speaker 21 and the second speaker 22 share a sealed cavity, and the second speaker 22 and the third speaker 23 share a sealed cavity, after the first speaker 21, the second speaker 22 and the third speaker 23 are connected to the same electrical signal, the front 211 of the radiation basin of the first speaker can push the front 221 of the radiation basin of the second speaker, and the back 222 of the radiation basin of the second speaker can push the back 232 of the radiation basin of the third speaker, so that the first speaker 21, the second speaker 22 and the third speaker 23 all move in the same direction and at the same frequency, so that the distortion rate of the bass speaker 100 can be reduced and the sound effect can be improved. Exemplarily, by setting the distortion rate of the three speakers to one third of the distortion rate when one speaker is set.

It should be noted that since the first sealed cavity 113 is formed between the first speaker 21 and the second speaker 22, when the first speaker 21 and the second speaker 22 move in the same direction, the front face 211 of the radiation basin of the first speaker and the front face 221 of the radiation basin of the second speaker can push each other, so that the first speaker 21 and the second speaker 22 move at the same frequency and in the same direction, which can reduce distortion and enhance bass sound effects.

Similarly, a second sealed cavity 114 is formed between the second speaker 22 and the third speaker 23, so that when the second speaker 22 and the third speaker 23 move in the same direction, the back side 222 of the radiation basin of the second speaker and the back side 232 of the radiation basin of the third speaker can push each other, so that the second speaker 22 and the third speaker 23 move at the same frequency and in the same direction, which can reduce distortion and enhance bass sound effects.

In a possible implementation, the first speaker 21 and the second speaker 22 are connected in anti-phase parallel or anti-phase series. The third speaker 23 and the second speaker 22 are connected in anti-phase parallel or anti-phase series.

In this way, the first speaker 21, the second speaker 22 and the third speaker 23 can be conveniently controlled to vibrate in the same direction, thereby increasing the volume of the bass, so that more bass that is not easy to express can be expressed, and distortion can be reduced and the bass sound effect can be improved.

As shown in FIG2 , when in use, since the first speaker 21 and the second speaker 22 are connected in anti-phase parallel or anti-phase series. The third speaker 23 and the second speaker 22 are also connected in anti-phase parallel or anti-phase series, after receiving the same electrical signal, the first speaker 21, the second speaker 22 and the third speaker 23 move in the same direction, for example, the first speaker 21, the second speaker 22 and the third speaker 23 all move along the solid arrow in FIG2 . Alternatively, the first speaker 21, the second speaker 22 and the third speaker 23 all move along the dotted arrow in FIG2 . This reduces bass distortion and improves sound quality.

It should be noted that the first speaker 21, the second speaker 22 and the third speaker 23 move in the same direction, which means that at any moment the movement directions of the first speaker 21, the second speaker 22 and the third speaker 23 are the same, that is, the vibration frequencies and vibration directions of the first speaker 21, the second speaker 22 and the third speaker 23 are the same.
