Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a schematic structural diagram of a mobile terminal according to an embodiment of the present invention is shown, where the mobile terminal includes a sound generator 1, and a first sound outlet 2 and a second sound outlet 3 are respectively disposed on two opposite sides of the mobile terminal, the first sound outlet 2 and the second sound outlet 3 share a sound cavity 4, the sound generator 1 is communicated with the sound cavity 4, and a sound outlet surface 11 of the sound generator faces the first sound outlet 2.
In the embodiment of the invention, two opposite side surfaces of the mobile terminal are respectively provided with the first sound outlet hole 2 and the second sound outlet hole 3, and correspondingly, the first sound outlet hole 2 and the second sound outlet hole 3 are respectively and correspondingly arranged on two screens of the double-sided screen mobile terminal. The screen includes a display screen portion and a non-display screen portion, and the first sound outlet hole 2 and the second sound outlet hole 3 may be provided in the non-display screen portion. The mobile terminal comprises a sound generator 1, wherein the sound generator 1 is communicated with a sound cavity 4, and the first sound outlet 2 and the second sound outlet 3 share the same sound cavity 4, wherein the sound outlet surface 11 of the sound generator 1 faces the first sound outlet 2. It can be seen from the above structure that when a user uses a screen on one side to answer a call or listen to a voice message, etc., the sound played by the sound generator 1 can be heard by the user from the sound outlet corresponding to the side screen after being transmitted through the sound cavity 4, thereby realizing the function of earphone playing on the side screen; when a user uses the screen on the other side to answer a call or listen to voice messages and the like, the sound played by the sound generator 1 can be transmitted through the sound cavity 4 and then heard by the user from the sound outlet corresponding to the side screen, so that the function of earphone playing is realized on the side screen. In conclusion, the mobile terminal of the embodiment can achieve the effect that the two screens can realize the earphone playing function, so that the functions and the use scenes of the mobile terminal with the double-sided screen are enriched.
In addition, as is well known, the receiver playing function of the mobile terminal is realized based on the sound generator 1, in order to avoid mutual interference caused by two side faces of the mobile terminal with a double-sided screen corresponding to one sound generator 1 respectively, in this embodiment, it is preferable that the two side faces of the mobile terminal share one sound generator 1, further, the sound generator 1 corresponds to a unique sound cavity 4, so that the first sound outlet 2 and the second sound outlet 3 share one sound cavity 4, and further, the interference between the two sound cavities 4 is avoided. Moreover, the mobile terminal is provided with the sounder 1, so that the cost can be reduced, the internal structure of the mobile terminal is simplified, the receiver playing structure is prevented from occupying too much space of the mobile terminal, and the performance of the terminal is optimized.
Preferably, the mobile terminal in this embodiment may further include: a first proximity sensor that detects the side toward which the first sound outlet 2 faces, and a second proximity sensor that detects the side toward which the second sound outlet 3 faces.
Referring to fig. 1, fig. 1 is a cross-sectional view of a dual-screen mobile terminal, which includes a first screen 201 and a second screen 301 disposed opposite to each other, and a first sound hole 2 may be disposed on the first screen 201, and a second sound hole 3 may be disposed on the second screen 301. The user may listen to the sound played by the handset using the first screen 201 or the second screen 301, and the user may stick the screen to the ear while listening. If the user listens to the sound played by the receiver through the first screen 201, the first proximity sensor may detect the ear of the user near the first screen 201, thereby determining the first sound outlet 2 as the main sound outlet; if the user uses the second screen 301 to listen to the sound played by the handset, the second proximity sensor may detect the user's ear near the second screen 301, thereby determining the second sound outlet 3 as the primary sound outlet.
As can be seen, the first proximity sensor is used to detect an object, such as a user's ear, near the side toward which the first sound outlet 2 is directed; the second proximity sensor is used to detect an object, such as a user's ear, near the side toward which the second sound outlet hole 3 faces. When the mobile terminal realizes the earphone playing function, the screen used by the current user can be determined according to the detection results of the first proximity sensor and the second proximity sensor, so that the screen can be turned off to reduce the display power consumption.
It is conceivable that if only one side of the mobile terminal is provided with the sound outlet, the sound outlet surface 11 faces the sound outlet, so as to ensure the volume and quality of sound. In the present embodiment, it is proposed that the first sound outlet 2 and the second sound outlet 3 share one sound cavity 4, and in order to ensure that the sound played by the sound outlet surface 11 can be played from the first sound outlet 2 and the second sound outlet 3 through the sound cavity 4, the sound outlet surface 11 of the sound generator 1 may be inclined between the two side surfaces of the mobile terminal and face the first sound outlet 2, so that the sound played by the sound outlet surface 11 can be played from the first sound outlet 2 and the second sound outlet 3 through the sound cavity 4 and played with different sound effects.
Referring to fig. 1, further, the mobile terminal further includes a housing 5, the first screen 201 and the second screen 301 are arranged in parallel, edges of the first screen 201 and the second screen 301 are connected through the housing 5, and the first sound outlet 2 and the second sound outlet 3 are arranged oppositely. In addition, the first sound outlet hole and the second sound outlet hole may not be arranged oppositely. The sound generator 1 is obliquely installed between the first screen 201 and the second screen 301, and within the sound chamber 4, the first screen 201 faces the first sound emitting hole 2 so that the maximum sound energy of the sound generator 1 is emitted from the first sound emitting hole 2 on the first screen 201.
Specifically, the housing 5 includes a middle frame structure, and the first screen 201 and the second screen 301 may be respectively installed at opposite sides of the middle frame structure, and the middle frame structure plays a role of connecting and fixing the first screen 201 and the second screen 301. Further, the first sound outlet 2 is disposed at the top area of the first screen 201, so that a user can conveniently receive a call, the second sound outlet 3 is disposed opposite to the first sound outlet 2, and the second sound outlet 3 is disposed at the top area of the second screen 301.
In practice, the first screen 201 is provided with a first sound outlet 2 in the area corresponding to the sound cavity 4, the second screen 301 is provided with a second sound outlet 3 in the area corresponding to the sound cavity 4, the sound outlet surface 11 faces the first sound outlet 2, the sound outlet surfaces 11 of the first screen 201, the second screen 301 and the sound generator 1 and the shell 5 form a closed sound cavity 4, and the sound outlet for playing is formed in the cavity wall of the sound cavity 4. So that the sound played by the sound-emitting surface 11 is played from the sound-emitting opening via the sound chamber 4, and the user listens to the sound at the sound-emitting opening. In the sound cavity 4, the sound emitting surface 11 of the sound generator 1 faces the first sound emitting hole 2, so that the first screen 201 where the first sound emitting hole 2 is located can be used as a main screen for realizing the earphone playing function, and the second screen 301 can be used as an auxiliary screen for realizing the earphone playing function, so that the performance of the earphone playing function of the original main screen can be kept on the premise of ensuring the realization of the double-side earphone playing function.
Further, based on the above structure, the mobile terminal further includes:
the audio parameter memory is used for storing a first audio parameter and a second audio parameter, and the first audio parameter and the second audio parameter are different;
the audio processor is used for selecting a target audio parameter according to the detection results of the first proximity sensor and the second proximity sensor, and processing an audio signal to be output by using the target audio parameter, wherein the target audio parameter is one of the first audio parameter and the second audio parameter;
and the decoder is used for decoding the processed audio signal and reducing the decoded audio signal into an analog audio signal for the sounder to play.
Preferably, when the screen used by the current user is determined to be the first screen 201 according to the detection results of the first proximity sensor and the second proximity sensor, the first audio parameter can be used to process the audio signal to be output so as to optimize the audio signal to be output, so that the optimized audio signal is decoded and restored into the analog audio signal to be played by the sound generator 1; or, when the screen used by the current user is determined to be the second screen 301 according to the detection results of the first proximity sensor and the second proximity sensor, the second audio parameter may be called to process the audio signal to be output so as to optimize the audio signal to be output, so that the optimized audio signal is decoded and restored into the analog audio signal, and then is played by the sound generator 1.
The difference is that, in the first case, the main sound outlet is the first sound outlet 2, and as the sound outlet 11 faces the first sound outlet 2 with respect to the position relationship between the first sound outlet 2 and the sound outlet surface 11 of the sound generator 1, after the audio signal is played from the first sound outlet 2, the achieved volume can meet the performance requirement, but if only the earphone playing structure composed of the sound cavity 4 and the first sound outlet 2 is considered, the second sound outlet 3 is an opening on the sound cavity 4, so that the sound cavity 4 has a sound leakage problem at the second sound outlet 3, and therefore the high frequency part in the audio signal is attenuated, and therefore the first audio parameter is more important than optimizing the frequency response curve of the high frequency part to compensate for the high frequency attenuation caused by the structure setting. It can be seen that the degree of high frequency optimization produced by the first audio parameter is greater than the degree of frequency optimization produced by the second audio parameter.
In the second case, the main sound outlet is the second sound outlet 3, and for the position relationship between the second sound outlet 3 and the sound outlet surface 11 of the sound generator 1, the sound outlet surface 11 does not face the second sound outlet 3, so that after the audio signal is played from the second sound outlet 3, the achieved volume is low, and the audio signal has slight distortion, so that the second audio parameter emphasizes on the insufficiency of the optimized volume and the audio distortion. As can be seen, the volume optimization degree generated by the first audio parameter is less than the volume optimization degree generated by the second audio parameter; the first audio parameter produces a distortion optimization level that is less than the distortion optimization level produced by the second audio parameter.
It can be seen that, in this embodiment, according to the relative position relation between the first sound hole 2, the second sound hole 3, and the sound emitting surface 11 of the sound generator 1, the audio parameters are set reasonably, and according to different use conditions, the corresponding audio parameters are called to perform optimization processing on the audio signal to be output, so as to ensure high-quality sound in the play function of the receiver of the mobile terminal, thereby not only avoiding the interference of the two screens, but also ensuring high-quality sound of normal play and play of the two screens.
Preferably, the sound generator 1 is a moving-coil receiver, one side of the moving-coil receiver includes a diaphragm assembly, and the side where the diaphragm assembly is located is the sound emitting surface 11 of the sound generator 1.
Compared with a ceramic receiver or an exciter receiver and the like, the receiver using the ceramic receiver or the exciter receiver is obviously inferior to the traditional moving coil receiver in sound quality due to the defects of the receiver in the design principle. Therefore, the mobile terminal with the double-sided screen can make sound from the front side and the back side by adopting the traditional moving coil type receiver and combining the switching of two sets of audio parameters through the innovative design of the sound cavity structure of the receiver on the basis of considering the front-back receiving tone quality.
Fig. 2 shows a block diagram of a mobile terminal according to an embodiment of the present invention, wherein the audio processor is preferably a Digital Signal Processing (DSP) system 7 and the DECoder is preferably an audio CODEC (CODEC) 8.
Illustratively, applied to the mobile terminal, the implementation process of the earphone play function is as follows: after determining that the current user is closer to the screen according to the detection results of the first proximity sensor and the second proximity sensor, a Central Processing Unit (CPU) 6 sends a corresponding instruction to a DSP system 7, the DSP system 7 calls a corresponding audio parameter according to the instruction and performs optimization processing on the detected audio signal, further the DSP system 7 sends the optimized audio signal to a CODEC 8, the CODEC 8 converts a digital signal corresponding to the audio signal into an analog signal, and the sound generator 1 plays the audio signal. Therefore, based on different application scenes, the DSP system 7 calls different audio parameters to perform optimization processing, so that the tone quality of the sounder 1 on the front side and the back side of the mobile terminal can be optimized, the sounder 1 on the mobile terminal can emit sound on the two sides effectively, the receiving tone quality of the sound emitted on the front side and the back side can be considered, and the convenience and the satisfaction of a user using the double-sided screen mobile terminal are improved.
The DSP system 7 is preferably a digital signal processing chip manufactured by Analog Device Instrument (ADI), i.e., the DSP system 7 is an ADSP system.
Example two
Fig. 3 is a flowchart illustrating an audio playing method according to another embodiment of the present invention, which is applied to a mobile terminal according to a first embodiment of the present invention, and includes:
step S1: and acquiring the target side of the mobile terminal, which is close to the mobile terminal by the external object relative to the mobile terminal.
In the use scenario of the earpiece play function, the user can use either side of the mobile terminal to listen to the sound played by the sound generator 1.
When the user listens to the sound, the habit acts as: the mobile terminal is brought close to the ear to listen to the sound from the sound outlet hole. Therefore, in this step, the ear is used as an external object to detect which side the user is closer to, and the side closer to the user is used as a target side, which is acquired as the side currently used by the user.
For example, a user listens to the sound played by the sound generator 1 at a side corresponding to the first screen 201 of the mobile terminal, and the sound is a front use scene of the earphone play function, and a target side in the front use scene is the first screen 201; the user listens to the sound played by the sound generator 1 at the side corresponding to the second screen 301 of the mobile terminal, and the back use scene of the earphone playing function is shown, and the target side in the back use scene is the second screen 301.

Step S3: the processed audio signal is decoded and restored into an analog audio signal for being played by a sounder.
In the embodiment of the invention, in the use scene of the earphone playing function, a user can use any side of the mobile terminal to listen to the sound played by the sound generator 1, so that the user can be used as an external object, one side surface which is closer to a user is obtained from two opposite side surfaces of the mobile terminal and is used as a target side surface which is used by the user currently, therefore, the sound outlet on the target side surface plays a main sound transmission role, calling corresponding audio parameters to process the audio signal to be output according to the position relation between the sound outlet hole on the side surface of the target and the sound outlet surface 11 of the sounder 1, so as to focus more on optimizing the insufficient part of the audio signal on the basis of optimizing the audio signal as a whole, and then the audio signal after the optimization processing is decoded and restored to be an analog audio signal, the sound generator 1 plays the analog audio signal, and a user listens to sound through a sound outlet on the side surface of the target. Therefore, in the audio playing method of the embodiment, the receiver playing functions of the two sides of the mobile terminal can be realized, and the tone quality of playing sound can be ensured no matter which side of the receiver plays the application scene, so that not only are the functions and the use scenes of the mobile terminal with the double-sided screen enriched, but also the use experience of a user is ensured.
Preferably, the volume optimization degree generated by the first audio parameter is smaller than the volume optimization degree generated by the second audio parameter;
the first audio parameter produces a distortion optimization level that is less than the distortion optimization level produced by the second audio parameter.
Referring to fig. 4, preferably, step S2 includes:
step S21: the frequency response curve of the high-frequency part in the audio signal to be output is optimized by the first audio parameter.
The first audio parameter needs to emphasize the optimization of the frequency response curve of the high frequency part due to attenuation of the high frequency part in the audio signal to be output.
Referring to fig. 5, further, step S21 includes:
step S211: enhancing the frequency response of the high frequency part of the audio signal to be output, and/or boosting the dynamic range of the high frequency part of the audio signal to be output by MBDRC.
Specifically, the frequency response of the high frequency part may be enhanced, or the Dynamic Range of the high frequency part may be improved by using a Multi-band Dynamic Range Control (MBDRC).
Referring to fig. 6, preferably, step S2 includes:
step S22: and performing at least one of the following operations on the audio signal to be output according to the second audio parameter: gain enhancement, loudness enhancement and low frequency response suppression.
The optimization adjustment mainly aimed at by the second audio parameter may be to increase gain and enhance loudness, or to make frequency response suppression optimization for a frequency band portion which is easy to be distorted in combination with a digital Filter (FIR), a digital filter (IIR) and an MDRC function, so as to optimize a distortion portion in the audio signal to be output, and optimize the volume of the audio signal to be output.
The frequency band susceptible to distortion is a low frequency portion, such as a frequency band within 1 kHz.
The audio playing method provided by the embodiment of the present invention is applied to each mobile terminal in the device embodiment implementing the first embodiment, and is not described herein again in order to avoid repetition.
