Description

Technical Field

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

[0002] Micro earphones are a popular choice for many users due to their compact size and portability. They are often used in situations where concealment is required or where carrying large earphones is inconvenient. Micro earphone speakers operate on the principle of MEMS technology, where a tiny diaphragm vibrates under the action of an electric field, thereby producing sound.

[0003] Publication number CN 212910041 U discloses a loudspeaker using a novel sound diaphragm. The loudspeaker includes a bracket, one end of which is provided with an annular column having a through hole for accommodating a magnetic cover, thereby solving the problem of large mass and low sound pressure output of the existing loudspeaker vibration system.

[0004] The speaker adopts the new sound diaphragm. The coil clamped between the inner sound diaphragm and the outer sound diaphragm is lighter, which reduces the mass of the entire vibration system and thus improves the sound pressure output. However, the device does not have a dust-proof device for the speaker. When external dirt falls onto the surface of the speaker, it affects the pronunciation of the speaker, making the speaker's pronunciation non-standard and affecting its use. Therefore, improvement is needed. Utility Model Content
