Technical Field
The invention relates to the technical field of electroacoustic products, in particular to a vibrating diaphragm capable of linearly moving and an artificial intelligent sound box.
Background
And a diaphragm, namely a passive radiator. It is one of the parts of electroacoustic sound box products, and it is moved by the action force produced by extruding the air in the box body during the movement process of the loudspeaker, so it is also called passive basin.
Referring to fig. 1, a traditional diaphragm is sequentially provided with an
In the actual production process, the sound is easy to distort after the mass of the weight part is increased, and if the artificial intelligence sound box is applied to the artificial intelligence sound box, the tone quality and the awakening rate of the artificial intelligence sound box are greatly influenced. Therefore, it is necessary to improve the existing diaphragm to solve the problem that the diaphragm is easily distorted after the weight of the weight-added part is increased.
Disclosure of Invention
An object of the present invention is to provide a linearly movable diaphragm and an artificial intelligence speaker, which can effectively solve the problem that the conventional diaphragm is easily distorted after the weight of the weight-added part is increased.
In order to achieve the above object, in one aspect, the present invention provides a linearly movable diaphragm, including a weight portion, a folded ring portion located at an outer ring of the weight portion, and a gully portion connecting the weight portion and the folded ring portion; the weight part comprises a coating layer connected with the gully part and a weight fixedly connected with the coating layer, and the density of the weight is greater than that of the coating layer;
the thickness dimension of the channel portion in the axial direction is 1/2 of the thickness dimension of the weight portion in the axial direction.
Optionally, an accommodating cavity is formed inside the coating layer, and the weight is located in the accommodating cavity.
Optionally, a gap for communicating the accommodating cavity with the external space is formed in the coating layer.
Optionally, the opening direction of the folded ring part is the same as or opposite to the direction of the notch.
Optionally, the coating layer, the groove punching part and the folding ring part are of an integrally formed structure.
Optionally, the weight and the coating layer are fixedly connected in a membrane hot-pressing mode.
Optionally, the coating layer, the groove part and the folding ring part are all made of rubber or silica gel.
Optionally, the weight is made of metal.
In another aspect, the present invention provides an artificial intelligence speaker, including any one of the above linearly movable diaphragms.
The invention has the beneficial effects that: the utility model provides a but linear motion vibrating diaphragm and artificial intelligence audio amplifier, the part of additional weight is cladding and additional weight, when needs increase or reduce the quality of additional weight part in order to change polarization parameter, can select thicker or thinner additional weight part for use. Meanwhile, the thickness of the channel part changes along with the thickness of the weight part, and particularly, researches show that when the thickness of the channel part along the axial direction is 1/2 of the thickness of the weight part along the axial direction, proper support can be provided for the weight part, the polarization motion of the weight part is not limited too much, and the diaphragm is not easy to generate deflection and distortion.
