Abstract

The invention discloses a loudspeaker and a mobile terminal with the same. The loudspeaker comprises a first coil, a second coil, a shed frame, inner magnetic steel, a pair of first external magnetic steel, a pair of second external magnetic steel and a magnetic bowl. The first coil and the second coil are integrated and fixed together and fixed on the shed frame together. The inner magnetic steel, the first external magnetic steel and the second external magnetic steel are fixed on the magnetic bowl. The magnetic bowl is fixed on one side, away from the first coil and the second coil, of the shed frame. When the loudspeaker provides changeable magnetic fields, the first coil and the second coil sense the changeable magnetic fields and generate sensing current, thereby wirelessly charging a cell. According to the invention, by integrating the first coil and the second coil in the loudspeaker, the charging function and the loudspeaker function are achieved simultaneously; inner space of the mobile terminal is saved; cost of the whole machine is reduced; and the endurance time of the cell is increased.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a loudspeaker and a mobile terminal with the loudspeaker. Background technique [0002] With the rapid development of mobile terminals such as mobile phones and rapid technological updates, the market demand for mobile terminal products and Internet access products continues to expand. Due to the portability of mobile terminal products, the requirements for ultra-thin and ultra-light are also getting higher and higher. The functions of existing mobile terminals such as mobile phones are becoming more and more powerful, and a considerable number of functions are integrated, such as: mobile phone battery life, wireless charging technology Become a mobile hotspot technology. The existing battery life and wireless charging functions of mobile phones have at least the following disadvantages: 1. high cost; 2. increased thickness of the whole machine; 3. poor portability of ...
