Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe.

It is a kind of structural representation of embodiment of audio player provided by the utility model referring to Fig. 1.Such as Fig. 1 institutes Show, the audio player includes：Main control chip 1, display module 2, voice module 3, power module 4, key-press module 5 and humiture Detection module 6.Wherein, main control chip 1 respectively with display module 2, voice module 3, power module 4, key-press module 5, humiture Detection module 6 connects；Power module 4 is connected with display module 2.

In the present embodiment, Temperature and Humidity module 6 is model DHT11 Temperature Humidity Sensor, and it is internal including one The wet device of individual sense and a temperature measuring device, and be connected with 8 single-chip microcomputers.Single-chip microcomputer passes through to feeling wet device and thermal detector Part carries out digital independent and stored, then is communicated by main control chip 1 with single-chip microcomputer, it is possible to which realization is adopted to outside humiture Collection.After main control chip 1 obtains corresponding data of the Temperature and Humidity module, user is shown to by display module 2.The pin connection of the DHT11 Fig. 2 is for details, reference can be made to, Fig. 2 is the pin connection diagram of Temperature Humidity Sensor provided by the utility model.

In the present embodiment, voice module 3 includes：Speech chip and loudspeaker.Speech chip is model BY8001 Speech chip, loudspeaker are connected with speech chip.Detailed attachment structure can be found in Fig. 3, and Fig. 3 is voice provided by the utility model A kind of structural representation of embodiment of module.As shown in figure 3, the optimal supply voltage required for BY8001 chips is 4.2V, Therefore need to set diode by system 5V power voltage step downs to 4.3V, and SPK1 the and SPK2 pins of loudspeaker and the chip connect Connect.

In the present embodiment, main control chip 1 is the chip of model STM32F103 series.The chip energy consumption control, into There is larger advantage in this control.Wherein, the clocking scheme of the main control chip 1 may refer in Fig. 6.

In this example it is shown that module 2 includes display screen and slide rheostat；Slide rheostat and the display screen Pin connection is displayed contrast, specific connection figure can be found in Fig. 4.The slide rheostat is used for the contrast for adjusting display screen, keeps away It is too high and produce ghost to exempt from contrast.Display module 2 can be with the humiture of display environment, volume, total number of songs and current sound Happy number.

In this example it is shown that screen is model LCD1602 LCDs.

In the present embodiment, key-press module sets 6 buttons, including a upper song, Xia Yiqu, broadcasting, pause, volume increasing altogether And volume down.

As one kind citing of the present embodiment, audio player also includes reset circuit；Reset circuit and the master control core Piece connects.The particular circuit configurations of the reset circuit are as shown in figure 5, the reset circuit is sent out in the startup of system and running Wave important effect.

Therefore the audio player that the utility model embodiment provides, humiture can be provided for outdoor exercises user Simultaneously display function is detected, improves the practicality and multifunctionality of audio player.And hardware design of the present utility model is base Constructed in STM32, simple in construction, cost is low, suitable for large-scale promotion.

Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit Decorations are also considered as the scope of protection of the utility model.
