Description
Technical Field
The present invention relates to the field of electronic product technologies, and in particular, to a mobile terminal and a control method of the mobile terminal.
Background
The basic function of the mobile terminal is conversation, and sound devices such as a receiver (or called a receiver), a microphone, a loudspeaker and the like are indispensable, so that a user can realize conversation with a contact person at an opposite end through the sound devices. The conventional sound device needs to be provided with a sound outlet hole to receive or output sound due to the structure of its sound cavity, for example, as shown in fig. 1, a sound outlet hole 111 of a receiver is provided at the top of the front side of the mobile terminal (i.e. the end surface where the display screen of the mobile terminal is located).
As the mobile terminal screen is developed to a high screen ratio, the display area of the front side of the mobile terminal is larger and larger, and even the whole front side is the display area, as shown in fig. 2a to 2c, which are schematic diagrams of the development trend of the front side screen of the current mobile terminal, it is easy to see that the front side opening of the mobile terminal needs to be cancelled after the mobile terminal screen is developed to a full screen.
To solve this problem, taking the receiver as an example, the following method is generally adopted to solve the contradiction between the sound output hole of the receiver and the full-screen display: as shown in fig. 3, a ceramic receiver (or exciter) 112 is arranged in the mobile terminal, and a ceramic receiver or exciter is used to realize screen sounding, and since the ceramic receiver or exciter drives the screen or forms a vibration cavity between the screen and the middle frame, a sound cavity is not required to be arranged, so that the sound outlet hole can be omitted. However, the following disadvantages exist in the way of sound production: compared with the traditional vibration mode of the vibrating diaphragm, the sound of the receiver is smaller; because the whole screen part sounds, the sound leakage is easy to generate while the volume is increased; compared with the traditional diaphragm telephone receiver, the voice frequency response of the telephone receiver is poorer, and the voice quality is not good. That is, the screen sound generating method using the ceramic receiver or the exciter has a poor sound effect. In addition, taking the microphone as an example, in order to eliminate the opening on the front side of the mobile terminal, an opening needs to be formed on the back side or the side of the mobile terminal.
As can be seen from the above, the conventional technology has a problem that it is difficult to achieve both the sound effect of the sound device and the reduction of the number of openings of the mobile terminal.
