Problems solved by technology

[0004] More and more mobile phones are designed to be as small as possible, leaving very little space for the main speaker, which limits the size of the speaker selected as the main speaker
Therefore, the loudness and sound quality of the sound produced by the main speakers still cannot meet the expected needs

Embodiment Construction

[0037] As described in the Background of the Invention, a mobile phone with earphones and main speakers working independently in different modes suffers from many problems in producing loud and good quality sound. Practically any user equipment (UE) or user equipment using speakers of different sizes operating in different modes faces this problem. Embodiments of the present invention are provided to solve this problem.

[0038] figure 1 Shown is a user equipment 10 (also designated as UE 10 hereinafter) according to an embodiment of the invention. The UE 10 includes a processor 20 , a first speaker 30 and a second speaker 40 . It should be appreciated that the references to parts of UE 10 by using figure 1The communication components illustrated by the lines in are suitably interconnected. The processor 20 is used for providing the first driving signal to the first speaker 30 and providing the second driving signal to the second speaker 40 . The first speaker 30 and the ...

Abstract

The present application relates to a user device: a processor (20) configured to process an audio signal to derive a first driving signal and a second driving signal, such that the first driving signal comprises only components of the audio signal having frequencies higher than a threshold frequency and such that the second driving signal comprises components of the audio signal having frequencies above and below the threshold frequency; wherein the processor is configured to simultaneously provide the first driving signal and the second driving signal; a first speaker (30), being configured to generate sound based on the first driving signal; and a second speaker (40), being configured to generate sound based on the second driving signal. Furthermore, the present application also relates to a corresponding method, and a computer program.

Description

technical field [0001] The present invention relates to a user equipment. Furthermore, the invention also relates to a method of driving a loudspeaker in said user equipment and a computer program product for implementing said method. Background technique [0002] Mobile phones are largely used by people for communication, entertainment and so on. Typically, a mobile phone has two different components for producing sound, namely: earphones and a main speaker. In general, only the headset is used when the phone is operating in so-called handset mode or in handheld mode, and only the main speaker is used when the phone is operating in hands-free mode or in so-called tweeter mode. [0003] When a cell phone is used for entertainment, such as playing music, watching movies, and playing games, the cell phone typically operates in hands-free mode or tweeter mode. In this case, the phone is expected to produce loud and good quality sound. [0004] More and more mobile phones ar...
