    Abstract: The method for processing data of Bluetooth speaker includes: running a first program firmware before the Bluetooth speaker is awakened; awakening the Bluetooth speaker after detecting wake-up information by the first program firmware, and caching received speech data by the first program firmware; establishing connection with a terminal device, and transmitting the speech data to the terminal device; and switching from the first program firmware to the second program firmware for operation if a request for re-establishing connection from the terminal device is received after current connection with the terminal device is disconnected, and receiving speech data fed back by the terminal device through the second program firmware, and playing the speech data fed back by the terminal device. The present application can increase the space for storing speech data when the size of the storage space of a system is fixed, thereby caching more speech data.

    Abstract: An earphone noise reduction method and apparatus, which are applicable to the technical field of wearable devices. The earphone noise reduction method can include collecting, using an earphone microphone, a noise signal of an environment where the earphone microphone is placed. The method can also include transmitting the noise signal to a connected terminal or transmitting a noise value corresponding to the noise signal to the connected terminal. The method can further include receiving a judgement result returned by the terminal, and enabling a noise reduction function or disabling the noise reduction function according to the judgement result. Embodiments of the present disclosure can be realized without keys or toggle switches for noise reduction adjustment on earphones. Embodiments of the present disclosure are capable of automatic noise reduction, thereby improving the integration degree of the earphones and also enhancing the battery life of the earphones.
