[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, the present invention provides a loudspeaker with a self-cleaning resonating cavity, including a housing 1 and a loudspeaker body 2 fixed on the housing 1. The housing 1 has a resonating cavity inside, and the loudspeaker body 2 is located inside the resonating cavity. The loudspeaker body 2 includes an upper housing 101 and a lower housing 102. The lower housing 102 is fixedly installed on the lower part of the upper housing 101 by a screw. The inner walls of the upper housing 101 and the lower housing 102 are respectively provided with transmission channels 5. The two transmission channels 5 are symmetrically arranged. The transmission channels 5 are irregularly shaped. The transmission channel 5 on the upper housing 101 is used for air intake, and the transmission channel 5 on the lower housing 102 is used for exhaust and dust removal.

[0024] The speaker with a self-cleaning resonating cavity described above emits sound through the speaker body 2 during installation and use, and then enhances the bass effect in conjunction with the resonating cavity of the housing 1.

[0025] To solve the problem of dust accumulation inside the resonance cavity, transmission channels 5 are provided on the inner walls of the upper housing 101 and the lower housing 102. When the diaphragm of the speaker vibrates, the two transmission channels 5 perform air intake and exhaust actions respectively. Since the transmission channel 5 of the lower housing 102 can remove dust from the inside of the resonance cavity under the action of vibration and airflow.

[0026] In this embodiment, during air intake, a guide channel is formed inside the transmission channel 5 located in the lower housing 102, and during gas reversal, a diversion channel is formed inside the transmission channel 5.

[0027] Since the transmission channel 5 is composed of multiple arc-shaped channels, the arc-shaped channels act as guides when the air is being introduced. However, when the gas flows in reverse, the arc-shaped channels weaken the transmission potential energy, thus achieving the function of a one-way valve. This allows the transmission channel 5 of the upper housing 101 to only perform air intake, while the transmission channel 5 of the lower housing 102 only performs exhaust and dust removal.

[0028] In the embodiment, the upper shell 101 is provided with a first through hole 6, and a socket 3 for connecting a plug from outside is fixedly installed on the upper shell 101 near the first through hole 6, and the socket 3 is electrically connected with the speaker body 2 through a wire penetrating through the first through hole 6.

[0029] When electrically connected with the external device, the wire is first connected with the speaker body 2, then the wire is fixedly connected with the socket 3 through the first through hole 6, and then the plug of the external device is plugged into the socket 3 to complete the electrical connection operation, thereby controlling the speaker body 2.

[0030] In the embodiment, the upper shell 101 is provided with a first through hole 6, and a socket 3 for connecting a plug from outside is fixedly installed on the upper shell 101 near the first through hole 6, and the socket 3 is electrically connected with the speaker body 2 through a wire penetrating through the first through hole 6.

[0031] When air is taken in through the transmission channel 5 of the upper shell 101, the baffle 4 can effectively block part of dust from entering the transmission channel 5 under the influence of gravity, and when the assembled shell 1 is fixedly installed by the bolt 7 and the nut, the upper shell 101 and the lower shell 102 are fixedly installed.

[0032] In the embodiment, the lower shell 102 is externally provided with a third through hole 104 for being fixed on a device, the upper shell 101 is internally provided with a plurality of shunt plates 106 arranged in a circumferential array near a mounting groove of the speaker body 2, part of the shunt plates 106 are fixedly connected with first partition plates 105, the first partition plates 105 are arranged in a longitudinal and transverse staggered manner, and the lower shell 102 is internally fixedly connected with second partition plates 107 arranged in a longitudinal and transverse staggered manner.

[0033] When the utility model is installed on a device, the third through hole 104 is used in cooperation with a screw or other tools to fix and install, meanwhile, the shunt plates 106 are arranged in a circumferential array near the mounting groove of the speaker body 2 in the upper shell 101, part of the shunt plates 106 are fixedly connected with the first partition plates 105, the first partition plates 105 are arranged in a longitudinal and transverse staggered manner, and the second partition plates 107 arranged in a longitudinal and transverse staggered manner are fixedly connected in the lower shell 102, thereby realizing the shunting of sound and the bass enhancement operation of the small cavities formed between the plurality of first partition plates 105 and the small cavities formed between the plurality of second partition plates 107.

[0034] The working principle of the utility model is as follows:

[0035] When using in the installation, the sound is emitted through the loudspeaker body 2, and then the bass effect is enhanced by matching the resonance cavity of the cabinet 1; in order to solve the problem of dust accumulation in the resonance cavity, transmission channels 5 are arranged on the inner walls of the upper shell 101 and the lower shell 102, when the diaphragm of the loudspeaker vibrates, the two transmission channels 5 respectively perform the air intake and exhaust action, and the transmission channel 5 of the lower shell 102 at the lower part can perform the dust removal operation on the dust in the resonance cavity under the action of vibration and airflow.
