Embodiment Construction

[0017] In order to introduce the present invention more clearly, the following first briefly introduces the principle of the speaker and the traditional audio power amplifier circuit.

[0018] See figure 1 , figure 1 It is a schematic diagram of the structure of the speaker of a mobile device. The sound of the speaker is mainly realized by changing the current flowing through the voice coil to drive the diaphragm to vibrate and produce different sounds.

[0019] Further integration figure 2 , figure 2 It is a schematic diagram of a traditional audio power amplifier circuit. In the traditional audio power amplifier circuit, it is a one-way drive and cannot monitor the status of the speaker. The amplitude and temperature are unknown. The speaker can only be driven with a small power. The performance of the speaker is limited, which leads to mobile devices. The volume is too low.

[0020] The present invention aims to solve the above technical problems in the prior art and provide an ...

Abstract

The invention discloses an intelligent audio system. The intelligent audio system comprises a digital signal processor (DSP), a power amplifier and a horn, wherein the DSP integrates a horn model; the horn model is used for describing relationships between the output power of the power amplifier and the amplitude of a horn diaphragm and between the output power of the power amplifier and the temperature of the horn diaphragm; and the DSP controls real-time output power of the power amplifier based on the horn model so as to control the output volume of the horn. Therefore, the intelligent audio system can ensure that sound distortion or horn damage is not caused when the horn performance is played as far as possible.

Description

Technical field [0001] The invention relates to an intelligent audio system. Background technique [0002] The speaker volume of current mobile devices is not high, mainly due to the following factors: small volume of the sound cavity, small amplitude of the speaker diaphragm, low battery voltage of the mobile device, limited power amplifier output capacity, and very limited speaker performance; even after some hardware Circuits (for example, boosting the power amplifier's drive capability through boost circuits) and certain software algorithms (Drac, Dolby, etc.) can only improve the performance of the speaker to a limited extent. The main reason is that the amplitude of the diaphragm and the The temperature is monitored. In order to ensure that the speaker diaphragm does not exceed the maximum displacement and cause the sound to be distorted or the temperature is too high to cause the speaker to be damaged, current mobile devices can only drive the speaker with a lower power wh...
