Abstract

A consumer electronic product comprises an electroacoustic element, a control unit which is connected with the electroacoustic element, and a pressure testing device, wherein the pressure testing device is connected with the control unit, the pressure testing device includes a capacitance sensing circuit, a movable terminal and a fixed terminal, the capacitance sensing circuit is connected to the control unit, the pressure testing device is used for detecting the environment atmosphere pressure size according to the variation of a capacitance value between the movable terminal and the fixed terminal, the control unit is used for generating control signals according to a mapping relationship between a preset atmosphere and an output drive power of the electroacoustic element and controlling the output drive power of the electroacoustic element, the pressure testing device also includes a support member and at least one air inflation cushion arranged between the movable terminal and the fixed terminal, and an elastic element is arranged between the movable terminal and the support member. The consumer electronic product provided protects the electroacoustic elements of the consumer electronic products and prolongs the service life of the consumer electronic products.

Description

technical field [0001] The invention relates to a consumer electronic product, in particular to a consumer electronic product capable of detecting the atmospheric pressure of the surrounding environment, and the consumer electronic product can adjust its sound output power according to the change of the surrounding environment pressure. Background technique [0002] At present, as a personal communication and multimedia entertainment terminal, mobile phones must use electro-acoustic components, such as receivers (RECEIVER), speakers (SPEAKER), and earphones used as a set. An important technical indicator of these electroacoustic components is the ambient atmospheric pressure. With the same driving power, the electro-acoustic components of the mobile phone work normally under a standard atmospheric pressure condition, but on a plateau, when the atmospheric pressure is lower than a standard atmospheric pressure, the electro-acoustic components such as the speaker and the earpi...
