Building interphone with loudspeaker module

Abstract

The utility model discloses a building interphone with a loudspeaker module. The building interphone comprises a shell, a positioning structure and the loudspeaker module. The shell is provided with a mounting cavity; the shell is also provided with a sound outlet communicated with the mounting cavity; the direction of a sliding mounting path of the loudspeaker module is parallel to the bottom plate of the shell; the positioning structure is located in the mounting cavity, the positioning structure comprises a stroke buckle and two positioning pieces which are oppositely arranged, and the stroke buckle and the two positioning pieces define a clamping area; the stroke buckle and the sound outlet are sequentially arranged at intervals along the direction of the sliding installation path. The loudspeaker module is installed in the clamping area. When the loudspeaker module is installed, the sliding direction of the loudspeaker module is parallel to the bottom plate instead of being perpendicular to the bottom plate, and therefore the phenomenon that the loudspeaker module and the shell are scratched in the gravity direction is avoided, and a sealing structure on the loudspeaker module is prevented from being scratched.

Description

Technical Field

[0001] The present application relates to the technical field of intercoms, and in particular to a building intercom with a speaker module. Background Art

[0002] At present, both the main unit and extension unit of building intercom (for the convenience of description, the main unit and extension unit are collectively referred to as the electronic control unit) need to be installed with a speaker module. The speaker module is generally installed close to the right angle edge of the shell, so that the sound of the speaker module can be directly transmitted to the outside of the electronic control unit. Furthermore, in order to prevent the sound generated by the speaker module from entering the inside of the electronic control unit, a sealing ring needs to be provided at the sound outlet of the speaker module, and the sealing ring needs to be tightly attached to the inner wall of the shell to ensure that the sound of the speaker module can be directly transmitted to the outside of the control unit.

[0003] In addition, in order to ensure the precise positioning of the speaker module, a vertical positioning column is required to position the speaker module. It should be supplemented that the vertical positioning column is parallel to the plane where the side wall of the shell is located, and the opening of the shell (i.e., the sound outlet) is arranged on the side wall of the shell. In this way, during the installation of the speaker module, the sealing ring is easily scratched by the side wall of the shell, or after installation, one side of the sealing ring is easily over-extended, thereby reducing its sealing life, or the sealing ring is easily not tightly connected to the inner wall of the shell (i.e., loose).

[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] join Figure 1-Figure 5 The building intercom with a speaker module of this embodiment includes: a housing 1, a positioning structure 2 and a speaker module 3.

[0031] The housing 1 has an installation cavity 11, and the housing 1 is also provided with a sound outlet 12 connected to the installation cavity 11; the direction of the sliding installation path of the speaker module 3 is parallel to the plate surface (equivalent to the top surface) of the bottom plate 13 of the housing 1. For ease of understanding, refer to Figure 4 The sliding installation path is in the horizontal direction and gradually approaches the sound outlet 12 from the middle of the shell 1.

[0032] The positioning structure 2 is located in the installation cavity 11. The positioning structure 2 includes a travel buckle 21 and two positioning members 22 arranged opposite to each other, the travel buckle 21 and the two positioning members 22 enclose a clamping area 23; the travel buckle 21 and the sound outlet 12 are arranged in sequence and spaced apart along the direction of the sliding installation path.

[0033] The speaker module 3 is installed in the clamping area 23, and two opposite sides of the speaker module 3 are respectively in contact with one of the positioning members 22 to prevent the speaker module 3 from shaking. One of the other two opposite sides of the speaker module 3 is in contact with the travel buckle 21, and the other side has a sound outlet 31 of the speaker module 3. The sound outlet 31 is arranged opposite to the sound outlet 12, and a sealing structure is provided between the sound outlet 31 and the sound outlet 12. Specifically, Figure 4 The speaker module 3 of this embodiment has a rectangular structure, that is, the outer contour of the speaker module 3 when viewed from above is a rectangular structure. Specifically, the left and right sides of the speaker module 3 are in contact with one of the positioning members 22, the rear side of the speaker module 3 is in contact with the travel buckle 21, and the front side of the speaker module 3 has a sound outlet 31 of the speaker module 3.

[0034] With this arrangement, when installing the speaker module 3, the sliding direction of the speaker module 3 is parallel to the bottom plate 13, rather than perpendicular to the bottom plate 13, thereby avoiding the speaker module 3 and the housing 1 from scratching in the direction of gravity, and avoiding scratching the sealing structure on the speaker module 3. Moreover, after the speaker module 3 is pushed horizontally into place, it is clamped by the travel buckle 21, thereby evenly compacting the sealing structure, thereby preventing the sealing structure from being subjected to unilateral force, thereby extending the service life of the sealing structure.

[0035] In this embodiment, in order to guide the installation of the speaker module 3, preferably, the positioning member 22 is a positioning bar, and the positioning bar is in contact with the side wall of the speaker module 3. It can be understood that as an alternative arrangement, the positioning member 22 can also be a protrusion or a bump.

[0036] In this embodiment, preferably, the sound outlet 12 is arranged on the side wall of the shell 1; the side wall of the shell 1 is connected to the connecting end of the positioning member 22, and the travel buckle 21 is connected to the free end of the positioning member 22. In this arrangement, the free end of the travel buckle 21 can swing relative to the connecting end of the travel buckle 21, so as to facilitate easy installation and removal of the speaker module 3. As an alternative arrangement: the travel buckle 21 can also be connected to the bottom plate 13. In comparison, the former positioning strip needs to be broken apart and automatically rebound to ensure the reliability of the limit, and also allows a slight dimensional accuracy error between the two, thereby reducing the difficulty of production.

[0037] In this embodiment, preferably, a plurality of sound outlets 12 are provided, and the plurality of sound outlets 12 are linearly arranged at intervals. This arrangement enables the size of each sound outlet 12 to be set smaller, so that the speaker module 3 is in a hidden state and is not likely to be bumped or damaged.

[0038] In this embodiment, in order to increase the volume, preferably, a plurality of speaker modules 3 and a plurality of positioning structures 2 are provided, and the plurality of speaker modules 3 and the plurality of positioning structures 2 are distributed in a one-to-one correspondence.

[0039] In this embodiment, in order to reduce the cost, preferably, the travel buckle 21 is made of plastic material. It is understandable that the buckle can also be made of metal material.

[0040] In this embodiment, in order to facilitate visual positioning and mounting, preferably, the sealing structure is a sealing ring, and the outer contour of the sealing ring is a rectangular structure.

[0041] In this embodiment, in order to prevent the sealing ring from falling off, preferably, the sealing ring is bonded to the housing 1 by glue.
