Document Type and Number:
WIPO Patent Application WO/2018/014431
Kind Code:
A1
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.
