The invention discloses an audio setting method of a mobile terminal. The method comprises the following steps: playing a sound source by the mobile terminal, and receiving feedback of a user on the sound source to test a hearing feature of the user; and modifying sound listened by the user when having a call by use of the mobile terminal according to the hearing feature of the user. The invention further discloses a mobile terminal achieving the method. By means of the manner, the audio setting method disclosed by the invention can be used for improving the auditory experience of the user when having a call.

The invention discloses an audio output POP (Post Office Protocol) sound eliminating circuit, which comprises a reference voltage generation module, a voltage follower and an audio amplifier; the reference voltage generation module is connected to the first input end of the voltage follower, and is grounded via a decoupling capacitor C1; the second input end of the voltage follower is connected to the output end of the voltage follower and the forward output end of the audio amplifier; the reverse input end of the audio amplifier is used for inputting audio signals; the output end of the audio amplifier is connected to one end of a direct current blocking capacitor C0; the other end of the direct current blocking capacitor C0 is used for connecting an audio player; the output end of the voltage follower and the output end of the audio amplifier are connected via a first CMOS (Complementary Metal Oxide Semiconductor) switch; and the first input end of the voltage follower and the output end of the audio amplifier are connected via a second CMOS switch. According to the audio output POP sound eliminating circuit disclosed by the invention, all POP sounds generated in power supply and outage process of the audio output as well as in startup and shutdown process of the audio amplifier can be completely eliminated, the auditory feeling is improved, the structure is simple and the cost is low.

The present invention relates to a system and method for splicing speech segments for speech synthesis. First, two speech segments to be spliced ​​are extracted from a speech bank as a first speech segment and a second speech segment, and the first speech segment and the second speech segment are Select the best sampling point in the second speech segment; then, carry out first-order smoothing to the best sampling point, generate speech splicing point; First-order smoothing method is: calculate the slope ka, kb at the best sampling point U1, U2 place, and The numerical difference value deltaU of the best sampling points U1 and U2; predict according to the slope ka, kb and the difference value deltaU, and generate a speech splicing point. Finally, a speech splicing point is inserted between the first speech segment and the second speech segment to generate a third speech segment. The present invention solves the problem of voice spectrum hopping that occurs in direct splicing in the prior art, and the problem of excessive calculation through the autocorrelation search and accumulation smoothing method, and obtains a good continuous frequency spectrum at the splicing place through the first-order smoothing method. and enhance the user's hearing experience.

The invention relates to a sound diffusing device and a loudspeaker with the sound diffusing device. The loudspeaker comprises a housing, a speaker unit, a sound guiding cone, a first partition, a second partition and a cover components. The speaker unit is located in the casing. The speaker unit has a sound output side. The sound guide cone has a sound guide cone surface. The sound output side of the speaker unit faces the sound guide cone. The first partition and the second partition are respectively connected to opposite ends of the mask assembly. The first baffle, the second baffle and the cover assembly are movably located on the sound guiding cone surface. When at least one of the first partition and the second partition is driven, the angle between the first partition and the second partition is changed. The sound diffusing device and the loudspeaker having the sound diffusing device disclosed in the present invention can take into account both advantages of omnidirectionality and directivity.
