Problems solved by technology

When the sound signal S9 emitted by the speaker 950 resonates in the speaker 940, the resonance effect in the bass frequency range becomes very poor
[0005] Therefore, how to propose a loudspeaker mechanism and an electronic device using it to solve the problem of poor bass frequency range effect caused by a small volume speaker is an important research and development direction at present.

[0029] Please also refer to figure 2 , image 3 , figure 2 Shown is a schematic diagram of the speaker mechanism 110 and the electronic device 100 applying it according to the first embodiment of the present invention. image 3 shown as figure 2 An exploded view of the speaker mechanism 110 and the electronic device 100 using it. The electronic device 100 includes a casing 120 , a control unit 140 and a speaker mechanism 110 . The control unit 140 is disposed in the casing 120 . The speaker mechanism 110 includes a speaker 111 , a speaker element 112 and a sound compensation element 113 . The speaker element 112 is disposed on the surface of the sound box 111 . The control unit 140 is electrically connected to the speaker element 112 to control the speaker element 112 to emit a sound signal S1. The sound compensating element 113 is disposed on the surface of the sound box 114 . The sound compensating element 113 includes a resonance film 1131 and a weighting element...

[0044] The speaker mechanism 210 of this embodiment and the electronic device 200 using it differ from the speaker mechanism 110 and the electronic device 100 using it in the first embodiment in the structure of the resonant thin film 2131 , and the rest of the similarities will not be repeated here. Please refer to FIG. 7 , which is a schematic diagram of a speaker mechanism 210 and an electronic device 200 using it according to a second embodiment of the present invention. In this embodiment, the center of the resonant thin film 2131 has a first thickness D1, and the edge of the resonant thin film 2131 has a second thickness D2, and the first thickness D1 is greater than the second thickness D2. Since the second thickness D2 at the edge of the resonant film 2131 is thinner, the edge of the resonant film 2131 is softer than the center. And the first thickness D1 at the center of the resonance film 2131 is thicker, so the center of the resonance film 2131 is thicker than the e...

[0046] The difference between the speaker mechanism 310 and the electronic device 300 of the present embodiment and the speaker mechanism 110 of the first embodiment and the electronic device 100 of the first embodiment lies in the structure of the speaker 311 , and the rest of the similarities will not be repeated here. Please refer to FIG. 8 , which is a schematic diagram of a speaker mechanism 310 and an electronic device 300 using it according to a third embodiment of the present invention. In this embodiment, the sound box 311 has a first opening 111a and a second opening 111b, the speaker element 112 is sealed in the first opening 111a, and the sound compensation element 113 is sealed in the second opening 111b, so that the sound box 311 forms an enclosed space. The sound box 311 only has a first opening 111a and a second opening 111b. The speaker element 111 and the sound compensating element 113 are respectively disposed behind the first opening 111a and the second ope...

Abstract

The invention provides a loudspeaker mechanism and an electric device using the same. The loudspeaking mechanism comprises a speaker, a loudspeaker element and a sound compensation element, wherein the loudspeaker element is arranged on the surface of the speaker; the loudspeaker element is used to send a sound signal; the sound compensation element is arranged on the surface of the speaker; the sound compensation element comprises a resonant membrane and a weight-increasing element; the resonant membrane and the sound signal are resonated in the range of resonant frequency so as to compensate the sound strength of the sound signal in the range of resonant frequency; the weight-increasing element is adhered to the surface of the resonant membrane; and the weight of the weight-increasing element is related to the range of resonant frequency.

Description

technical field [0001] The present invention relates to a speaker mechanism and an electronic device using it, and in particular to a small speaker mechanism and an electronic device using it. Background technique [0002] With the development of science and technology, various electronic devices are constantly being introduced, bringing many conveniences and unlimited fun to people's life. Among them, many electronic devices are equipped with speaker mechanisms. A sound signal can be broadcast through the speaker mechanism to play music, message or perform oral communication and other actions. [0003] Please refer to figure 1 , which is a schematic diagram of a conventional speaker mechanism 900 . The speaker mechanism 900 includes a sound box 940 and a speaker 950 . The speaker 950 includes a conductive coil 951 , a metal element 952 and a vibrating film 953 . The conductive coil 951 and the metal element 952 are disposed inside the sound box 940 , and the conductive...
