Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker blocker. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest device in the audio equipment, but it is also the most important component for the sound effect. Now the installation environment of speakers is mostly box-type installation, and the most common is the wooden box structure, while the car-mounted sound environment mainly uses the door sheet metal as the box.

[0003] When the speaker is working, the airflow generated by the reflection and refraction of the inner wall of the cabinet will have a great negative impact on the speaker diaphragm, causing the speaker diaphragm to be disturbed by the airflow in the cabinet when vibrating, which deteriorates the sound environment of the speaker and may cause the clarity and resolution of the sound emitted by the speaker to decrease. Therefore, a speaker blocker is proposed to address the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a loudspeaker blocker to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A speaker blocker comprises a speaker body and a bolt, wherein a mounting ring is fixedly connected to the outer side of the speaker body, a first screw hole is opened on the inner side of the mounting ring, a connecting ring is arranged at the bottom of the mounting ring, a second screw hole with the same aperture size is opened on the inner side of the connecting ring, a fixing tube is fixedly connected to the lower end face of the connecting ring, a spiral blade is fixedly connected to the inner wall of the fixing tube, and a positioning tube is fixedly connected to the side of the spiral blade away from the fixing tube.

[0007] Preferably, a damping pad is fixedly connected to the inner side of the positioning cylinder, and a plurality of through holes with equal apertures are formed on the inner side of the damping pad.

[0008] Preferably, the spiral blades are arranged in an equiangular array with the same center, and there are several spiral blades in total.

[0009] Preferably, the aperture size of the first screw hole is equal to the aperture size of the second screw hole, and the bolt passes through the first screw hole and the second screw hole at the same time.

[0010] Preferably, the damping pad is sleeved on the lower half of the speaker body, and the damping pad fits the speaker body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, a structure composed of a positioning cylinder, spiral blades, a fixing cylinder and a connecting ring is set, and a cylindrical structure is sleeved on the outside of the speaker body to block the reflected and refracted airflow in the box, reduce the amount of air reaching the diaphragm of the speaker body, and then change the direction of the incoming and outgoing air through the spiral blades to reduce and block the influence of the reflected airflow on the diaphragm. The spiral angle of the blades will cause the airflow to produce a certain rotation when entering the cylindrical structure, thereby reducing the impact of the airflow on the diaphragm of the speaker body, improving the sound environment of the speaker body, and achieving the purpose of improving the clarity and resolution of the sound emitted by the speaker body.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0021] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
