For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a new type of Bluetooth FM transmitter, including a lower shell 1, a positioning rod is symmetrically installed on the left side of the top of the lower shell 1, a digital tube 3 is placed in the lower shell 1, and a limiting hole is opened on the left side of the digital tube 3 corresponding to the positioning rod. The positioning rod passes through the limiting hole to limit the digital tube 3 on the lower shell 1 to prevent the digital tube 3 from shaking on the lower shell 1 during use. A microphone is installed in the middle of the left side of the top of the digital tube 3, a button 5 is clamped on the top of the upper front side of the lower shell 1, an elastic part corresponding to the button 5 is installed on the front side of the digital tube 3, and the rear side of the button 5 abuts against the elastic part on the front side of the digital tube 3, an upper shell 2 is installed on the top of the lower shell 1, a display screen 4 is installed on the top of the upper shell 2, and the display screen 4 is electrically connected to the digital tube 3, and a circular limiting hole is set on the left side of the bottom of the upper shell 2 corresponding to the positioning rod in the lower shell 1 The bottom of the circular limit block is provided with a hexagonal limit hole. The hexagonal limit hole at the bottom of the circular limit block and the positioning rod are used in combination to fix the upper shell 2 and then the lower shell 1 together, and then the digital tube 3 and the button 5 are fixed between the lower shell 1 and the upper shell 2. The right side of the upper shell 2 and the lower shell 1 is installed with a USB connection port; when it is needed, the digital tube 3 is fixed in the shell by using the limit block and the positioning rod to prevent the digital tube 3 from shaking during use, which is convenient for reducing the process, reducing the cost and improving the assembly efficiency. The command is transmitted to the digital tube 3 by pressing the button 5, and the digital tube 3 transmits the signal to the display screen 4 to realize timely data change control of the Bluetooth FM transmitter. When the microphone on the digital tube 3 receives the signal, the microphone transmits the signal to the digital tube 3, and the digital tube 3 emits a prompt sound. Pressing the button 5 can answer or hang up the call.
[0022] like Figure 2 As shown, the button 5 includes a button 1 51, a button 2 52 and a button 3 53. The button 1 51 is located on the left side, and a "+" mark is printed on the front side of the button 1 51. The button 2 52 is located in the middle, and an "M" mark is printed on the front side of the button 2 52. The button 3 53 is located on the right side, and a "-" mark is printed on the front side of the button 3 53. Single-clicking the button 3 53 is to play the previous song, and long pressing the button 3 53 is to reduce the volume. Single-clicking the button 1 51 is to play the next song, and long pressing the button 1 51 is to increase the volume. Single-clicking the button 2 52 is to pause, play, answer a call or hang up a call.

[0023] Working principle: Place the digital tube 3 on the lower shell 1 through the positioning rod on the lower shell 1, install the front button 5, install the display screen 4 on the upper shell 2 and connect it to the digital tube 3, and the upper shell 2 is clamped together with the lower shell 1 through the hexagonal limiting hole opened at the bottom of the circular limiting block and the positioning rod. After the upper shell 2 and the lower shell 1 are clamped and fixed with the digital tube 3 and the fixed button 5, when it is necessary to switch playback, single-click button three 53 for the previous song, single-click button one 51 for the next song, and long-press button three 53 for volume reduction, long-press button One 51 is volume increase. When you answer a call or need to pause playback, you only need to click button two 52. When you need to switch frequency bands, enter the frequency band adjustment mode by long pressing button two 52, and the screen will flash slowly. When you need to reduce the frequency, click button three 53 to reduce the frequency by 0.1. Long pressing button three 53 will continuously reduce the frequency, and the frequency will stop decreasing after releasing it. When you need to increase the frequency, click button one 51 to increase the frequency by 0.1. Long pressing button one 51 will continuously reduce the frequency, and the frequency will stop increasing after releasing it. Click button two 52 again to exit the frequency band adjustment mode, and the screen will stop flashing.
