Problems solved by technology

[0004] However, the piezoelectric ceramic speaker 20 only has a sounding function, so the vibrator 30 is still needed, and the vibrator 30 still occupies a certain volume, and at the same time increases the material cost and assembly cost

Embodiment 1

[0017] see figure 2 , an embodiment of the mobile terminal of the present invention is proposed, and the mobile terminal includes a casing 100 and a speaker 200 . The speaker 200 is arranged on the casing 100 , and the speaker 200 generates sound by driving the casing 100 to vibrate.

[0018] In some embodiments, the speaker 200 includes a piezoelectric horn 300 .

[0019] In other embodiments, the speaker 200 includes a piezoelectric horn 300 and a moving coil horn (not shown).

[0020] The piezoelectric horn 300 can be mounted on the casing 100 or can be packaged in the casing 100 .

[0021] Of course, in some embodiments, the position of the piezoelectric horn 300 on the casing 100 can be moved, which can facilitate consumers to adjust the piezoelectric horn 300 so that its effect is optimal.

[0022] When a call comes in, the piezoelectric horn 300 can convert the electrical signal into mechanical vibration, thereby driving the casing 100 to vibrate and produce sound. ...

Embodiment 2

[0025] Similar to Embodiment 1, the difference lies in that the mobile terminal further includes a sensor and a processor disposed on the mobile terminal.

[0026] Wherein, the sensor is used for sensing the distance between the mobile terminal and the user's ear.

[0027] The processor is used to compare the distance sensed by the sensor with the preset range, and select one of the piezoelectric horn or the dynamic horn as the sound output device of the mobile terminal according to the comparison result.

Embodiment 3

[0029] Similar to Embodiment 1, the difference lies in that the mobile terminal further includes a sensor and a processor disposed on the mobile terminal.

[0030] Wherein, the sensor is used for sensing the sound condition of the environment where the mobile terminal is located.

[0031] The processor is used for selecting one of the piezoelectric horn or the moving coil horn as the sound output device of the mobile terminal according to the sound condition sensed by the sensor.

Abstract

The invention discloses a mobile terminal, which comprises a case and a loudspeaker arranged on the case, wherein the loudspeaker produces sound through driving the case to vibrate, and comprises a piezoelectric loudspeaker. The mobile terminal has the advantages that the loudspeaker is arranged on the case of the mobile terminal and produces the sound through driving the case to vibrate, the traditional loudspeaker and the vibrator are replaced, parts are reduced, the material cost and the assembly cost are reduced, the production cost is further reduced, and in addition, the mobile terminal can be lighter and thinner.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal. Background technique [0002] Mobile terminals have been fully integrated into people's lives and become an indispensable tool for modern people. Mobile terminals have more functions and more complex structures, but people's requirements for the appearance of mobile terminals are becoming thinner and lighter, which requires fewer components and smaller volumes to form mobile terminals. [0003] In order to meet the user's demand for thinner and lighter mobile terminals, piezoelectric ceramic speakers are applied to mobile terminals in the prior art, such as figure 1 As shown, the mobile terminal includes a baseband circuit 10 and a piezoelectric ceramic speaker 20 and a vibrator 30 electrically connected to the baseband circuit. The traditional speaker and receiver are replaced by the relatively light and thin characteristics of piezoelectric ce...
