Problems solved by technology

[0004] The above existing solutions have the following disadvantages: (1) because most of the existing housing interior chambers for accommodating loudspeakers have asymmetry problems (such as Figure 1-2 As shown in , both the front chamber and the rear chamber of the shell have their own asymmetrical problems), so the linearity of the vibration of the speaker diaphragm is not good, resulting in high distortion
(2) If the input power to the speaker box exceeds the rated power, the speaker diaphragm may vibrate too much and hit the shell to cause noise, and even cause damage to the diaphragm and the speaker

Embodiment 1

[0037] refer to Figure 3-4 , the present invention provides a box body provided with a loudspeaker device, including a housing 1, a loudspeaker 2 is arranged in the housing 1, and the loudspeaker 2 has a diaphragm 201; There is a vibration space 4 , and at least one elastic component 3 is connected between the diaphragm 201 and the inner wall of the casing 1 .

[0038] Among them, the device provided with the speaker can specifically be a mobile phone, a tablet, a computer, a speaker, a TV, etc., and there is no limitation here; the above-mentioned casing 1 refers to the casing of the speaker box, and the speaker box will be installed in the main body of mobile phones, computers and other equipment. inside the shell.

[0039] In the present invention, an elastic component is added between the loudspeaker diaphragm and the casing, so that the vibration of the diaphragm tends to be balanced, the nonlinear vibration of the diaphragm is reduced, and the effects of improving dist...

Embodiment 2

[0049] refer to Figure 7-8 , the present invention provides a box body provided with a loudspeaker device, including a housing 1, a loudspeaker 2 is arranged in the housing 1, and the loudspeaker 2 has a diaphragm 201; In the vibration space, at least one elastic member 3 is arranged on the diaphragm 201 ; one end of the elastic member 3 is located inside the housing and connected to the diaphragm 201 , and the other end protrudes from the housing 1 and is connected to the outer part 5 of the housing 1 .

[0050] Wherein, the device provided with the speaker can specifically be a mobile phone, a tablet, a computer, a sound box, a TV, etc., and there is no limitation here; the above-mentioned casing 1 refers to the casing of the speaker box.

[0051]Wherein, the above-mentioned outer component 5 can specifically be the outer casing of the box itself of the device provided with the speaker (such as the main casing or the internal PCB board of equipment such as mobile phones, ta...

Abstract

The invention discloses a box equipped with a speaker. The box comprises a shell, the speaker is arranged in the shell, and the speaker is provided with a vibrating diaphragm; a vibrating space is reserved between the vibrating diaphragm and the inner wall of the shell, and at least one elastic part is connected between the vibrating diaphragm and the inner wall of the shell. By the addition of the elastic parts between the vibrating diaphragm of the speaker and the shell, vibration of the vibrating diaphragm approaches equilibrium, nonlinear vibration of the vibrating diaphragm is reduced, and effects of improving distortion and tony quality are achieved.

Description

technical field [0001] The invention relates to the technical field of loudspeaker design, in particular to a box body of a device provided with a loudspeaker. Background technique [0002] Loudspeakers are installed in many existing electrical devices, such as sound boxes, mobile phones, tablets, computers, televisions, etc., to play the role of sound generation. [0003] like Figure 1-2 As shown in , usually the above-mentioned electrical equipment includes a casing, and the speaker is arranged in the casing, and there is a gap between the horn diaphragm of the speaker and the casing, as a vibration space for the horn diaphragm, within the vibration area of ​​the diaphragm ( figure 2 ) There are no other components connecting the diaphragm to the housing. [0004] The above existing solutions have the following disadvantages: (1) because most of the existing housing interior chambers for accommodating loudspeakers have asymmetry problems (such as Figure 1-2 As shown in...
