Problems solved by technology

When the receiver is working, the vibration motor generally does not vibrate. Even if it vibrates, the signal used by the vibration is a specific vibration signal, not an audio signal, and its function can only serve as a reminder. For example, when there is a new message, the vibration The motor will vibrate for a short time, which will make an annoying sound, which will greatly damage the sound quality and even affect the normal call

Embodiment 1

[0041] see figure 1 , is a schematic structural diagram of Embodiment 1 of the system for improving the sound quality of a mobile terminal in earpiece mode provided by the present invention.

[0042]The system 1 for improving the sound quality of the mobile terminal earpiece mode includes a first signal path 11 and a second signal path 13 connected in parallel, and the first signal path 11 includes a first power amplifier 111 and a receiver 113 electrically connected, so The second signal path 13 includes a second power amplifier 131 and a vibration motor 133 electrically connected. The first signal path 11 and the second signal path 13 are respectively used for transmitting voice signals. The first power amplifier 111 and the second power amplifier 131 are respectively used to adjust the gain of the voice signal output to the receiver 113 and the vibration motor 133, and the receiver 113 and the vibration motor 133 receive and Play a voice signal. The sound emitted by the ...

Embodiment 2

[0044] Please refer to figure 2 , is a schematic structural diagram of Embodiment 2 of the system for improving the sound quality of a mobile terminal in earpiece mode provided by the present invention.

[0045] Different from Embodiment 1, the second signal path 23 further includes a low-pass filter 231 . Specifically, the system 2 for improving the sound quality in the handset mode of a mobile terminal includes a first signal path 21 and a second signal path 23 connected in parallel, and the first signal path 21 includes a first power amplifier 211 and a first power amplifier 211 electrically connected in series. The receiver 213 , the second signal path 23 includes a low-pass filter 231 , a second power amplifier 233 and a vibration motor 235 electrically connected in series in sequence.

[0046] The low-pass filter 231 is used to filter out voice signals higher than a preset cut-off frequency among the voice signals output to the vibration motor 235 . By adding a low-pa...

Embodiment 3

[0048] Please refer to image 3 , is a schematic structural diagram of Embodiment 3 of the system for improving the sound quality of a mobile terminal in earpiece mode provided by the present invention.

[0049] Different from Embodiment 1, the first signal path 31 further includes a high-pass filter 311 . Specifically, the system 3 for improving the sound quality in the handset mode of the mobile terminal includes a first signal path 31 and a second signal path 33 connected in parallel, and the first signal path 31 includes a high-pass filter 311, a high-pass filter 311, The first power amplifier 313 and the receiver 315 , the second signal path 33 includes a second power amplifier 331 and a vibration motor 333 electrically connected in series.

[0050] The high-pass filter 311 is used to filter part of the low-frequency signals, preventing excessive low-frequency signals from making the receiver 315 work with too large amplitude and easy to be damaged. By adding a high-pas...

Abstract

The invention provides a system and method for improving the voice quality of a mobile terminal in a receiver mode. The system for improving the voice quality of the mobile terminal in the receiver mode comprises a first signal channel and a second signal channel which are arranged in parallel; the first signal channel comprises a first power amplifier and a receiver which are electrically connected; the second signal channel comprises a second power amplifier and a vibration motor which are electrically connected; the receiver and the vibration motor simultaneously receive and play voice signals; the first power amplifier and the second power amplifier are respectively used for adjusting the gains of the voice signals output to the receiver and the vibration motor. According to the system and the method provided by the invention, when the receiver sounds, the vibration motor vibrates synchronously according to the voice signals and drives the mobile phone to vibrate and sound; the voice generated by the vibration of the vibration motor and the voice generated by the receiver are combined; the better voice quality is obtained; and the better low frequency, the better high frequency or the higher loudness is obtained.

Description

【Technical field】 [0001] The present invention relates to the technical field of audio systems of mobile terminals, in particular to a system for improving the sound quality of a mobile terminal in earpiece mode and a method for improving the sound quality of a mobile terminal in earpiece mode. 【Background technique】 [0002] As we all know, a mobile phone contains a sound-generating device. Generally speaking, there are two kinds of sound-generating devices, one is called a receiver (also called a receiver), and the other is called a loudspeaker (commonly known as a loudspeaker). The handset is mainly used in "handset mode" and the speaker is generally used in "speaker mode". In the "earpiece mode", users need to put their ears close to the earpiece of the mobile phone to hear the sound from the earpiece clearly. The earpiece needs to be acoustically designed to have the best acoustic response when coupled with the human ear, so that the phone can achieve better privacy in...
