Micro loudspeaker

Abstract

The invention discloses a micro loudspeaker which comprises a vibrating diaphragm and a housing, wherein the vibrating diaphragm comprises a ball top and a folding ring part, and is supported and fixed through the housing; a combined part is arranged at the part, connected with the housing, of the edge of the vibrating diaphragm; the combined part of the vibrating diaphragm is adhered and fixed to the housing through an adhesive layer; the combined part of the vibrating diaphragm is combined with a bonding surface of the upper surface of the housing; an excessive glue groove used for accommodating excessive glue is formed in the edge of the outer side of the bonding surface and is covered with the edge of the outer side of the combined part of the vibrating diaphragm. The micro loudspeaker disclosed by the invention has the advantages that the excessive glue groove is formed in the bonding surface of the vibrating diaphragm and the housing, so that excessive glue generated during the process of vibrating diaphragm fixing can be fully adsorbed, the situation that the periphery of the vibrating diaphragm cannot be fixed and a magnetic circuit system is damaged due to uneven gluing is avoided, and meanwhile, the normal flow direction of glue can be ensured and the glue is prevented from moving upwards, therefore, the fixing of the vibrating diaphragm is completed better and the performance of the loudspeaker is ensured.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a micro speaker. Background technique [0002] In the structure of traditional micro-speakers, the diaphragm as one of the components of the vibration system is usually bonded and fixed with the shell as the support system. However, in the specific fixing process, there will often be uneven glue application, and glue overflow is one of its manifestations. In this case, the outer ring of the diaphragm will be lifted due to excessive glue application, which cannot be well fixed. Fix it to the shell, and at the same time, the overflowing glue may drip into the magnetic circuit or other structures of the speaker along the outer periphery of the glue layer, which will affect the performance of the micro-speaker. [0003] Therefore, it is necessary to improve the structure of the existing micro-speaker, especially the bonding and fixing process of the vibrating membrane, properly handl...
