The above structure has only one loudspeaker body. If you need to amplify the handset mode, you need to place the mobile phone upside down in the slot of the mobile phone, and you cannot switch between the handset mode or the built-in loudspeaker at will; the above structure The mobile phone slot of the mobile phone is directly connected to the sound amplifying port through the cylindrical sound guide cavity. Although it can improve the sound quality and increase the volume, the sound expansion is limited due to the small structure of the sound guide cavity and the sound amplifying port. Reach a certain level of external sound, the sound of the mobile phone should not be too low

The present invention discloses a loudspeaker. The loudspeaker is fixedly connected with a lower loudspeaking body and an upper loudspeaking body, wherein the lower loudspeaking body comprises a flexural shell and a plurality of sound sending bodies, and the sound sending bodies are located in the lower loudspeaking port of the flexural shell; the upper loudspeaking body comprises an upper loudspeaking port, a slot and a leading-note cylinder, the upper loudspeaking port is located at the periphery of the lower loudspeaking body, the leading-note cylinder is located in the flexural shell, and the leading-note cylinder is communicated with the sound sending bodies, the slot is located at the side wall of the upper loudspeaking port, and the slot is communicated with the leading-note cylinder. Through adoption of the structure, the loudspeaker is convenient to use and operate, small in shock, good in loudspeaking effect, good in tone quality and high in sound integrity.
Description
technical field [0001] The invention relates to the technical field of mobile phone accessories, in particular to a loudspeaker. Background technique [0002] As the mobile phone has more and more functions and is more and more convenient to use, it has become one of the indispensable tools for people. Now people use mobile phones to listen to music, watch videos, mobile phone navigation, etc. If you use the earpiece mode, the sound quality is good, but it will be inconvenient to use it for a long time or when driving. You can use earphones. Using earphones for a long time will not only damage the ears damage, and the earphones have requirements on the distance, so they can’t be used as you like. You can also use the built-in amplifying device of the mobile phone, but if the volume of the mobile phone is too high for a long time, it will cause damage to the mobile phone, and it is easy to generate noise, so people usually use an external amplifying device. Speakers are used...
