Loudspeaker and electronic device
Provided is a loudspeaker applied to an electronic device, including: a speaker body configured for vibrating and producing sound; a first acoustic channel having a first end communicated with the speaker body and a second end forming a first sound output port on a case of the electronic device; and a second acoustic channel having a first end communicated with the speaker body and a second end forming a second sound output port on the case of the electronic device. The first and second sound output ports are located on adjacent wall surfaces of the case of the electronic device. Compared with the related art, larger port area can be achieved by separately forming sound output ports on adjacent walls of the housing, resulting in high frequency response and higher gain. The horn-shaped sound output port facilitates design and reduces flow-related distortion and noise at low frequencies.
1. A loudspeaker, applied to an electronic device, comprising:
a speaker body configured for vibrating and producing sound;
a first acoustic channel having a first end communicated with the speaker body and a second end forming a first sound output port on a case of the electronic device; and
a second acoustic channel having a first end communicated with the speaker body and a second end forming a second sound output port on the case of the electronic device,
wherein the first sound output port and the second sound output port are located on adjacent wall surfaces of the case of the electronic device, a wall surface of the speaker body connected with the first acoustic channel is oblique with respect to the wall surface of the case of the electronic device on which the first sound output port is located, a wall surface of the speaker body connected with the second acoustic channel is oblique with respect to the wall surface of the case of the electronic device on which the second sound output port is located, each of the first acoustic channel and the second acoustic channel has a horn-shaped structure, the horn-shaped structure rotates at a certain angle.
2. The loudspeaker according to claim 1 , wherein an inner diameter of the first sound output port is different from an inner diameter of the second sound output port.
3. The loudspeaker according to claim 1 , wherein the first acoustic channel and the second acoustic channel are connected to opposite wall surfaces of the speaker body.
4. The loudspeaker according to claim 1 , wherein the first acoustic channel and the second acoustic channel are both provided with a sound absorbing material.
5. An electronic device, comprising a case and a loudspeaker installed in the case, wherein the loudspeaker comprises:
a speaker body configured for vibrating and producing sound;
a first acoustic channel having a first end communicated with the speaker body and a second end forming a first sound output port on a case of the electronic device; and
a second acoustic channel having a first end communicated with the speaker body and a second end forming a second sound output port on the case of the electronic device,
wherein the first sound output port and the second sound output port are located on adjacent wall surfaces of the case of the electronic device, a wall surface of the speaker body connected with the first acoustic channel is oblique with respect to the wall surface of the case of the electronic device on which the first sound output port is located, a wall surface of the speaker body connected with the second acoustic channel is oblique with respect to the wall surface of the case of the electronic device on which the second sound output port is located, each of the first acoustic channel and the second acoustic channel has a horn-shaped structure, the horn-shaped structure rotates at a certain angle.
