Description

Technical Field

[0001] The utility model relates to the technical field of electroacoustic converters, in particular to a loudspeaker. Background Art

[0002] The speaker includes a loudspeaker and a box with an opening. The loudspeaker is arranged at the opening. The loudspeaker and the inner surface of the box together form a back cavity. For the convenience of carrying, consumers often hope that the size of the Bluetooth speaker is relatively small. However, when the size of the speaker becomes smaller, the volume of the back cavity will also become smaller accordingly. When the volume of the back cavity becomes smaller, the F0 of the speaker will increase, resulting in poor bass effect.

[0003] To achieve good bass, traditional small-volume speakers often adjust the speaker's compliance or weight to achieve a low F0. However, blindly adjusting compliance and weight will reduce the speaker's production yield, undoubtedly increasing costs.

[0004] Setting sound-absorbing particles in the back cavity can enlarge the virtual back cavity, thereby making the speaker obtain a lower F0 and making the bass effect richer. However, the sound-absorbing particles sometimes enter the inside of the speaker and collide with the vibration components of the speaker to produce noise, affecting the acoustic performance of the speaker. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a loudspeaker with a new structure, which has a high production yield and can isolate sound-absorbing particles.

[0009] a first colloid connecting the mounting portion and the lower fixing portion;

[0010] A second colloid is used to connect the upper fixing portion and the top ring frame.

[0011] Furthermore, the breathable isolation net is in a cone-shaped ring shape as a whole.

[0012] Furthermore, the breathable isolation net and the frame are an integral structure formed by integral injection molding.
