As shown in fig. 3, the BLE module is a bluetooth low energy module, which transmits data in real time and has a low power consumption characteristic, and is used for transmitting small data volume, in this embodiment, it is used for data transmission except for voice call (telephone, video call, etc.). The BLE module is respectively electrically connected with the voice recognition module and the sound box control module.

The BT module is a classic bluetooth module, which is used for the transmission of large data volumes. In this embodiment, it is used for data transmission of voice call. For example, when the user answers or makes a call to perform a voice call, the BT module is started to perform data transmission. The BT module is connected with the sound box control module.

The voice recognition module is used for recognizing a voice input command of a user and comprises an activation unit, a first command output unit and a second command output unit.

The activation unit is used for activating the voice recognition module from a sleep state when the BLE module establishes Bluetooth connection with a host. The activation unit is connected with the BLE module. In other words, when the sound box is in the power-on state and the BLE module does not establish the bluetooth connection with the host, the voice recognition module is in the sleep state to reduce the power consumption; when the BLE module establishes a bluetooth connection with the host, the voice recognition module is activated to listen to the voice input of the microphone 40.

The BLE module outputs an activation signal to activate the voice recognition module, and the following circuit design can be adopted: the voice recognition module is the singlechip, and the output of BLE module is connected with the interrupt end of voice recognition module, when BLE module output activating signal, for sending the interrupt to the singlechip for the singlechip is activated from the dormancy state.

When activated, the speech recognition module is in a listening state and may listen for input from the microphone 40. When the microphone 40 has a voice input, the voice recognition module recognizes a voice input command therein and performs different actions according to the recognition content.

The first command output unit is electrically connected to the speaker control module, and is configured to control the speaker control module to output a control signal to the speaker 30. In this embodiment, when the voice recognition module recognizes that the input signal of the microphone 40 is the contents of power on, power off, volume up, volume down, pause, and play, the first command output unit outputs a corresponding signal to the speaker control module, and the speaker control module controls the speaker 30 to implement the functions of power on, power off, volume up, volume down, pause, and play.

The second command output unit is electrically connected with the BLE module and used for outputting signals to the BLE module and transmitting control signals to a host through the BLE module. In this embodiment, when the voice recognition module recognizes that the input signal of the microphone 40 is a command language for calling a mobile phone voice assistant (for example, hi, siri), the second command output unit outputs a corresponding signal to the BLE module, and the BLE module communicates with the host to transmit the signal to the host.

As shown in fig. 3, the sound box control unit is configured to implement main body control of the sound box, and is connected to the voice recognition module, the BLE module, the BT module, the speaker 30, the control button 20, the USB interface, the AUX interface, the TF card slot, the power module, and the charging interface, and can implement the following functions:

the control functions of volume up, volume down, power on, power off, pause, play, previous and next of the sound box are realized through the voice input of the microphone 40 or the control key 20;

when the USB interface is inserted into a USB playing device (such as a USB flash disk), playing audio stored in the USB playing device; when the AUX interface is inserted into an audio line, playing audio stored in audio equipment (such as a computer); when the TF card slot is inserted into the TF card, playing the audio stored in the TF card;

when the charging interface is connected with the charger, the charging control of the power supply module is realized;

when the host computer and the loudspeaker box are communicated with each other through the BLE module, the loudspeaker box control module analyzes communication content, if large code stream data need to be transmitted, the loudspeaker box control module controls the BT module to be activated, and the BT module is communicated with the host computer through the BT module. For example, when the host receives an incoming call and needs to answer, the incoming call signal is transmitted to the audio control module through the BLE module, the audio control module controls the BT module to be activated, and the BT module communicates with the host to answer the call, so that the call quality is ensured. If the sound box control module does not need to transmit large code stream data after analyzing the data content, the BT module is kept in a dormant state, and the host and the sound box still communicate through the BLE module. Such as voice commands issued to the host, voice data replied by the voice assistant of the host, audio played by the host, etc.

Therefore, when the voice call is not carried out, the sound box carries out Bluetooth communication with the host through the BLE module, and the BT module sleeps, so that the power consumption is reduced; when voice call needs to be carried out, the BT module is activated, the loudspeaker box carries out Bluetooth communication with the host through the BT module, and therefore the call quality is guaranteed, functional characteristics and power consumption differences of the BT module and the BLE module can be fully utilized, power consumption of products is greatly reduced, and standby time is prolonged. Furthermore, the utility model discloses a wearing formula audio amplifier can realize speech control, and the speech recognition module acquiescence is in the sleep state and reduces the consumption, just can activate in order to monitor microphone 40's speech input when only BLE module is connected with the host computer establishment bluetooth, and also greatly reduced product consumption is in order to improve the product duration like this.

In order to ensure the wearing comfort, the sound box control module, the BLE module, the BT module, the power module, the microphone 40, the voice recognition module and other devices can be uniformly distributed on the left and right functional parts 15, so that the weights of the left and right functional parts 15 are consistent or basically consistent as far as possible.

While the invention has been described with reference to the above embodiments, the scope of the invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the invention.
