Description

Technical Field

[0001] The utility model relates to the field of loudspeakers, and in particular to an anti-howling loudspeaker. Background Art

[0002] As a commonly used electronic product, loudspeakers are used in many aspects of life. Common loudspeakers include wired loudspeakers and wireless loudspeakers. Among them, portable loudspeakers are usually used in occasions such as tour guide explanations, teaching, sales, publicity, and small gatherings. When using them, the loudspeaker is mostly clamped on the collar with a collar clip. However, in actual use, it is found that the use of a collar clip will cause the loudspeaker to be too close to the user's body and will frequently contact the user's body, causing the loudspeaker to whistle or even make a harsh sound, thereby destroying the speaking atmosphere and affecting the use effect. Utility Model Content

[0003] In view of this, the utility model provides an anti-howling loudspeaker.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] An anti-howling loudspeaker comprises a loudspeaker body and a hanger, wherein the hanger is detachably mounted on the loudspeaker body; the hanger comprises a chuck and a connecting column, wherein the connecting column is fixed on the chuck and is located between the chuck and the loudspeaker body, and a card slot is formed between the chuck and the loudspeaker body; a first magnetic block is provided on one end of the connecting column close to the loudspeaker body, and a second magnetic block is provided on the loudspeaker body, and the first magnetic block and the second magnetic block can attract each other.

[0018] Optionally, in a possible implementation manner, a third magnetic block is further provided on the chuck.

[0019] In the above technical solution, the third magnetic block is provided to facilitate the installation of the entire loudspeaker. When the loudspeaker is in use, the user can mount the loudspeaker on a collar or clothes by cooperating with the third magnetic block through another magnetic block. The installation method is simple and convenient, and can also further increase the distance between the loudspeaker body and the human body, thereby further reducing the risk of howling.
