The present invention provides an improved speaker structure, which includes a speaker body, a resonance body and at least one sound guiding portion. The resonance body includes a resonance film and a resonance film frame. The sound guiding portion includes a first sound guiding member, a second sound guiding member and a back frame unit. The speaker structure forms a sealed sound chamber by combining the speaker body, the resonance body and the at least one sound guiding portion. When the speaker body generates a front sound wave and a guiding sound wave, the front sound wave is transmitted within the sound chamber to the resonance film to enhance low frequency sound effect, and the guiding sound wave is transmitted within the resonance cavity and forms a back sound wave, thus reducing noise in the sound region and enabling better extension of the sound wave towards low frequency range. |

1. An improved speaker structure, comprising:
a speaker body, comprising a base, a drum paper, a yoke, a magnetic unit, a sound coil and a supporting column; a resonance body, comprising a resonance film and a resonance film frame, wherein one side of the resonance film is connected to the base to be surroundingly positioned around the speaker body, and the other side of the resonance film is positioned on the resonance film frame; and at least one sound guiding portion, comprising a first sound guiding member, a second sound guiding member and a back frame unit, wherein the first sound guiding member has a hollow first extruding structure extruding inwards and is correspondingly positioned on the second sound guiding member, and the second sound guiding member has a hollow second extruding structure extruding outwards and correspondingly supports the first sound guiding member, wherein the first extruding structure and the second extruding structure do not contact each other, wherein the first sound guiding member and the second sound guiding member form a resonance cavity, wherein a bottom portion of the second sound guiding member is provided with an opening, and a top portion of the second sound guiding member has two sides surroundingly connected to the resonance film frame, wherein the back frame unit is connected to the opening; wherein the speaker structure forms a sealed sound chamber by combining the speaker body, the resonance body and the at least one sound guiding portion; wherein a front sound wave and a guiding sound wave are generated by a resonance formed by the yoke of the speaker body and the first and second sound guiding members of the at least one sound guiding portion such that when the front sound wave and the guiding sound wave are generated from the speaker body, the front sound wave is transmitted within the sound chamber to the resonance film and drives the resonance film to generate a corresponding sound, and the guiding sound wave is transmitted within the resonance cavity and forms a back sound wave, passing through the opening and driving the back frame unit to vibrate and to generate a corresponding sound. |
