[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0022] In the description of the utility model, it is necessary to understand that the orientation or positional relation indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like is the orientation or positional relation based on the orientation or positional relation shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0023] In the utility model, unless another explicit provision and limitation, the terms "mount", "set", "connect", "fix", "screw" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through intermediate medium, can be the communication inside two elements or the interaction relationship of two elements, unless another explicit limitation, the above-mentioned terms in the utility model can be understood according to the specific meaning of the specific situation by the ordinary skill in the art.

[0024] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless another explicit specific limitation.

[0025] Embodiment one: as shown in the accompanying Figure 1 - the accompanying Figure 5 Fig. 1 is a schematic view of a microphone fixing device according to the utility model, which comprises a shell 1, the shell 1 is provided with a fixed groove 11, the fixed groove 11 is provided with a rubber sleeve 2, the rubber sleeve 2 is a soft rubber sleeve, the rubber sleeve 2 is provided with a microphone 3, the rubber sleeve 2 includes a microphone fixing part 21 for fixing the microphone 3, further includes a shell connecting part 22 for connecting with the shell 1, the microphone fixing part 21 and the shell connecting part 22 are provided with a buffer support part 23.
