  • Publication number: 20190320265
    Abstract: A touch Bluetooth headset includes a housing, a touchpad, a main board, a Bluetooth antenna, a first thimble and a second thimble. The touchpad is a flexible touchpad, the main board and the touchpad are opposite and fixed on the housing, and the touchpad is provided with a plurality of metal contacts. The first thimble and the second thimble have one end fixed to the main board and other end extending toward the touchpad and abutting against the metal contacts. The Bluetooth antenna is laid on the touchpad and connected to the metal contacts. The touch Bluetooth headset may be designed to be more miniaturized; additionally, an additional Bluetooth antenna is added in the touchpad and the Bluetooth antenna is jacked up by the above thimbles, which reduces the electromagnetic shielding, thereby the micro Bluetooth headset has a better signal transmission distance.

  • Publication number: 20190302867
    Abstract: The present disclosure is applicable to the technical field of loudspeaker and provides a method and apparatus for reducing continuous-wakeup delay of Bluetooth loudspeaker and a Bluetooth loudspeaker. The method for reducing continuous-wakeup delay of Bluetooth loudspeaker includes: resetting a wakeup flag bit to wait for a next wakeup when receiving a stop-recording instruction which is sent by a terminal equipment through a Bluetooth serial port communication protocol; and executing a wakeup-interruption operation again after a preset wakeup keyword is received. According to the present disclosure, time delay under a continuous-wakeup mode can be greatly reduced and a response speed of continuous-wakeup can be improved.

  • Publication number: 20190302866
    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.
