Description

Speaker module and electronic equipment

Technical Field

The present application relates to the field of electroacoustic conversion technology, and more particularly, the present application relates to a speaker module and an electronic device.

Background

At present, for example, electronic products such as mobile phones or flat panels are mainly used for pursuing stereo effect, and two speakers are usually required. One of the speakers is used as a loudspeaker (commonly called a speaker or a horn) for playing ring tones or music, and is disposed at the bottom of the mobile phone. The other speaker is used as an earpiece in a conversation (commonly called receiver or earpiece), and is placed on top of the handset. The side wall of the frame of the mobile phone and the front face of the top are simultaneously provided with holes, so that the two loudspeakers can be matched to realize a stereo effect.

However, with the stereo design described above, sound from the speaker at the top of the handset may also emanate from openings in the side walls of the handset bezel (i.e., the loud speaker holes), in addition to the openings in the front of the top of the handset (i.e., the receiver holes). Like this, when only using the conversation function, the phenomenon of revealing of conversation sound can appear in the trompil on the cell-phone frame lateral wall, and then leads to user's privacy to reveal. In order to improve the problem of sound leakage in the call mode, the existing solution is to use a separate sound tube to cooperate with a speaker located at the top of the mobile phone for dedicated call, but this will result in increased production cost and volume of the speaker.
