Abstract

An hybrid Bluetooth earphone comprises an ear case (1), a Bluetooth receiver (2) and a frequency divider (3). A first acoustic chamber (11) and a second acoustic chamber (12) which are independent from each other are arranged in the ear case (1). A dynamic speaker (4) is arranged in the first acoustic chamber (11). A balanced armature speaker (5) is arranged in the second acoustic chamber (12). The ear case (1) is provided with a first acoustic outlet (110) communicating with the first acoustic chamber (11). The ear case (1) is provided with a second acoustic outlet (120) communicating with the second acoustic chamber (12). The Bluetooth receiver (2), the dynamic speaker (4) and the balanced armature speaker (5) are electrically connected with the frequency divider (3), respectively. Due to the fact that the first acoustic chamber (11) and the second acoustic chamber (12) are independent from each other, mutual interference between the dynamic speaker (4) and the balanced armature speaker (5) is reduced, and the mutual interference between the sounds made by the two is also reduced, enabling the dynamic speaker (4) to have a warm tone and the balanced armature speaker (5) to have a resonant tone. The sounds of the two are respectively output from the first acoustic outlet (110) and the second acoustic outlet (120) to be mixed in the ear so that the sound quality can be further improved.

In one embodiment, the receiving chamber, the first sound chamber, and the second sound chamber are sequentially disposed, and the receiving chamber and the first sound chamber communicate with the second through hole through the first through hole, the first Inside a line hole A wire connecting the frequency divider and the moving coil horn is disposed, and the second wire hole is provided with a wire connecting the frequency divider and the moving iron horn.

In one embodiment, the first wire hole is filled with a sealing glue, and the second wire hole is filled with a sealing glue.

In one embodiment, the inner wall of the first sound chamber is provided with a mounting position, the moving ring horn is mounted on the mounting position and the first sound chamber is divided into a front sound chamber and a rear sound chamber.

In one embodiment, the ring-iron Bluetooth earphone further includes an earplug sleeve, the earplug sleeve is disposed on the ear shell, and the first sound outlet and the second sound outlet are respectively in communication with the earplug sleeve.

The advantages or principles of the foregoing technical solutions are described below:

The above-mentioned ring-iron Bluetooth headset, the Bluetooth receiver receives the audio signal and sends it to the frequency divider, the frequency divider splits the audio signal into a medium-low frequency signal and a medium-high frequency signal, and the low-frequency signal is provided to the dynamic ring speaker, and the medium-high frequency signal is provided to Moving iron horn. Since the first sound chamber and the second sound chamber are independent of each other, the mutual interference between the moving ring horn and the moving iron horn is reduced, and the mutual interference between the sounds of the two is also reduced, and the moving horn sounds warm and moving. The iron horn sounds bright, and the sounds of the two are mixed into the ear through the first sound outlet and the second sound outlet respectively, and the sound quality can be further improved.
