Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of loudspeakers, and in particular relates to a new type of loudspeaker. Background Art
[0002] In smart door lock applications, in smart door lock applications (on appliances such as range hoods, wall-mounted boilers, heating tables, etc.), the speakers used for voice broadcasts are generally installed with D20~D30, ordinary membrane single speakers with a height of less than 7mm (on appliances such as range hoods, wall-mounted boilers, heating tables, etc.), the speakers used for voice broadcasts are generally installed with D20~D30, ordinary membrane single speakers with a height of less than 7mm. This type of speaker has low power, and because it is a single-body installation, the sound is relatively scattered, and the auditory experience is relatively poor. In addition, the speakers that used ordinary mylar diaphragms in the past could only withstand a power of about 1W, and the sound was also relatively small.
[0003] To this end, a cavity speaker with the publication number "CN219697878U" belongs to the field of speaker technology. This speaker comprises a first housing, the first housing containing a chamber; a second housing mounted on the first housing and having an inlet connected to the chamber; a bracket within the second housing; a magnetic circuit device fixed to the bracket; a paper dome mounted above the magnetic circuit device; and a fabric membrane, the inner ring of which is connected to the outer ring of the paper dome, which is then connected to the second housing. The membrane and the paper dome seal the inlet. This speaker offers the advantages of a rich and powerful sound.
[0004] However, for the above-mentioned cavity speaker, although the wires pass through the notch and the through-hole into the cavity, the wires need to pass through the cavity from the top or bottom of the through-hole so that the wires can be squeezed against the inner wall of the through-hole, so that the wires are not easily pulled out of the through-hole, thereby reducing the occurrence of the wires being pulled apart. However, there are still the following more obvious defects during use: the notch and through-hole of the above-mentioned speaker shell are square structures for positioning the two wire harnesses. Since the two wire harnesses are elliptical structures, the two elliptical wire harnesses cannot match at the corners in the square through-hole and produce an active space, thereby causing friction between the two wire harnesses and the active space in the through-hole, and then causing the two wire harnesses to wear and break due to long-term friction. Utility Model Content
[0005] The purpose of the present invention is to provide a new type of loudspeaker to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new speaker, comprising:
[0007] A speaker cover, wherein the speaker cover is provided with a chamber for positioning and mounting the main structural components of the speaker. The chamber design adopts a dual-cavity structure, i.e., two sets of acoustic cavity structures. A speaker inner support is positioned inside the chamber for supporting and lifting the main structural components of the speaker. An elliptical wire hole is provided at one end of the inner side of the chamber to fit the elliptical wire.
[0008] The speaker lower cover is installed at the end of the speaker upper cover. The joint surface of the speaker upper cover and the speaker lower cover is provided with a positioning fusion seam integrated by ultrasonic fusion welding. The speaker lower cover is positioned with a speaker component that is positioned and assembled on the speaker inner support.
[0009] Preferably, top shell columns A are vertically provided at the four corners of the cavity of the upper cover of the speaker, and top shell columns B are provided at the four corners of the inner cavity of the lower cover of the speaker for inserting the top shell columns A into the positioning combination, so that the upper cover of the speaker, the lower cover of the speaker and the speaker components can be prevented from loosening after being combined.
[0010] Preferably, the outside of the speaker component is clamped with a clamping bracket for clamping and positioning the speaker component inside the shell, and positioning hole grooves A are provided at the four corners of the clamping bracket, which can enable the speaker upper cover and the speaker lower cover to be combined so that the speaker component can be positioned inside the shell using the clamping bracket to maintain stability, thereby avoiding the problem of the speaker component vibrating and hitting the shell during operation.
[0011] Preferably, the four corners of the speaker inner support are penetrated by positioning hole grooves B corresponding to the positioning hole grooves A. The speaker inner support is positioned inside the speaker upper cover through the positioning hole grooves B via the top shell column A, so that the speaker component is installed inside the speaker upper cover and the speaker lower cover to ensure stability during operation.
[0012] Preferably, the speaker component is positioned and installed inside the speaker lower cover through the positioning hole groove A on the clamping bracket and is combined with the speaker upper cover into one body, thereby achieving rapid installation and positioning of the speaker and ensuring that the speaker component remains stable.
[0013] Preferably, both sides of the cavity of the speaker cover are provided with inclined convex conditions inclined toward the opposite end to support the speaker inner support, so that the speaker inner support maintains a certain vertical distance from the inner cavity of the shell after supporting the speaker component, thereby avoiding the problem of resonance between the speaker and the shell.
[0014] Compared with the prior art, the technical effects and advantages of the present invention are as follows: the new speaker is provided with an elliptical wire threading hole at one end of the inner side of the cavity of the speaker upper cover, which is consistent with the elliptical wire, so that the two connected wire harnesses are passed through the speaker upper cover and the speaker lower cover to be connected to the speaker components through the threading hole before the speaker is assembled, and the two wire harnesses are elliptical in shape and arranged in the elliptical threading hole, so that the two wire harnesses are matched and connected with the elliptical threading hole, and no movable space is generated between the two wire harnesses and the inner side of the threading hole, so that the two wire harnesses are matched and positioned with the inner cavity of the threading hole and the phenomenon of loosening, friction and damage will not occur, so that the two wire harnesses can maintain a firm fit in the threading hole, and through the positioning fusion stitches set on the speaker upper cover and the speaker lower cover, the speaker upper cover and the speaker lower cover are combined and fused at one time through ultrasonic combination welding, which simplifies the assembly process to the greatest extent.
[0015] The cavity design of the speaker cover uses a dual-cavity structure, that is, two sets of sound cavity structures, so that the decibel value of the speaker sound can be amplified twice. On the basis of the sound generation of the speaker cavity, the sound decibel value is increased by 3 to 10 decibels through the combination of the external cavity. BRIEF DESCRIPTION OF THE DRAWINGS
