Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker with a diaphragm that is convenient to install. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but for the sound effect, it is the most important component. There are many types of speakers and the prices vary greatly. Audio electrical energy causes the paper cone or diaphragm to vibrate through electromagnetic, piezoelectric or electrostatic effects, and resonates with the surrounding air to produce sound.

[0003] In the existing technology, the speaker diaphragm is installed inside the speaker housing. When the speaker needs to be replaced and repaired, the diaphragm is difficult to remove inside the speaker housing, which is very troublesome and reduces the efficiency of maintenance work, and needs to be developed urgently.
