The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 8 The utility model discloses a doorbell, including a housing, a circuit board 20, a light source assembly and a speaker assembly 40. The housing is provided with an installation cavity and an installation opening, and the installation opening is connected with the installation cavity. The circuit board 20 and the light source assembly are both installed in the installation cavity, and the light source assembly is electrically connected with the circuit board 20. The speaker assembly 40 is installed in the installation opening, and the speaker assembly 40 can be electrically connected with the circuit board 20, and is used to send a ringing signal when the doorbell is working.

[0030] Specifically, the installation opening is covered with a panel 14 in a detachable manner, and after the panel 14 covers the installation opening, the outer edge of the panel 14 can be spaced apart from the inner circumferential wall to form a light guide opening 13. Of course, it should be noted that after the speaker is installed in the installation opening, it extends into the installation cavity through the installation opening, and the outer periphery of the speaker assembly 40 is spaced apart from the inner periphery of the installation opening. Therefore, even if the light guide opening 13 formed after the panel 14 lamp cover is located at the inner circumferential wall of the installation opening and the inner circumferential wall of the panel 14, the speaker assembly 40 will not block the light of the light assembly. The above-mentioned light guide opening 13 can guide the light of the light source assembly to be exported.

[0031] Based on the above structure, when the doorbell of the utility model is used, the switch on the doorbell can be used to touch the circuit board 20, so that the speaker assembly 40 emits a ringing signal as a reminder.

[0032] Specifically, when in use, the light source assembly can also be turned on by the switch on the doorbell, so that the light source assembly emits light. The light emitted by the light source assembly can be exported through the light guide port 13, so that position indication can be performed in a dimly lit environment, and it can also be used as a lighting decoration.

[0033] It should be noted that the above-mentioned panel 14 and shell are both made of non-light-transmitting materials in the prior art, so that the light generated by the light source assembly inside the installation cavity of the shell can be concentrated and guided out through the light guide port 13, and the concentrated lighting and decorative effects are better.

[0034] In addition, in order to facilitate the smooth output of the sound emitted by the speaker assembly 40, a plurality of sound-transmitting holes may be provided on the panel 14 for output of the sound.

[0035] Furthermore, in the present application, a light guide cover 16 may be provided in the installation cavity, the light guide cover 16 is arranged around the inner periphery of the installation opening, and the top of the light guide cover 16 extends to the light guide opening 13. The light source assembly is arranged below the light guide cover 16, and the light guide cover 16 is made of light-guiding material; the speaker assembly 40 is arranged inside the light guide cover 16; the panel 14 and the light guide cover 16 are detachably connected.

[0036] The above-mentioned light guide cover 16 can be made of materials such as light guide glass, acrylic plate or light guide plate in the prior art. The light source component is installed under the light guide cover 16. The light generated by the light source component can be guided to the top of the light guide cover 16. The top of the light guide cover 16 is located at the light guide port 13. Therefore, the light guided by the light guide cover 16 can be concentrated and exported at the light guide port 13. In this way, the light can be guided and concentrated by the light guide cover 16 to reduce the divergence of light.

[0037] On the basis of the structure provided with the light guide cover 16 , the speaker assembly 40 is arranged inside the light guide cover 16 , that is, the light guided out by the light guide cover 16 can avoid the speaker assembly 40 inside it and do not interfere with each other.

[0038] Further, see Figure 2 , Figure 3 as well as Figure 4 In this embodiment, a light guide cover 16 structure is provided, and the light guide cover 16 may include a first light guide ring 161 and a second light guide ring 162. The first light guide ring 161 is arranged on the inner side of the second light guide ring 162, and the top of the first light guide ring 161 is connected to the top of the second light guide ring 162, and the bottom of the first light guide ring 161 is spaced from the bottom of the second light guide ring 162. The first light guide ring 161 is arranged around the inner periphery of the installation port, and the top of the first light guide ring 161 extends to the light guide port 13, and the second light guide ring 162 is attached to the inner wall of the installation cavity; the light source assembly is arranged below the first light guide ring 161.

[0039] In this case, during assembly, the second light guide ring 162 is assembled to the inner wall of the installation cavity, and the corresponding first light guide ring 161 can be located below the installation port and surrounded by the inner circumference of the installation port to facilitate the assembly of the light guide cover 16. After assembly, the top of the first light guide ring can extend to the light guide port 13 to guide light.

[0040] Further, see Figure 6 , Figure 7 as well as Figure 8In the present embodiment, another structure of the light guide cover 16 is provided. On the basis of the structure of the light guide cover 16, a light guide groove 165 can be provided at the bottom end of the light guide cover 16, and the light source assembly is located in the light guide groove 165. In this way, after the light guide cover 16 is assembled into the mounting cavity, the top end of the light guide cover 16 can extend to the light guide port 13, and the light guide groove 165 is provided outside the light source assembly. In this way, the light generated by the light source assembly is directly guided to the top end through the light guide groove 165, and is concentratedly guided out to reduce the divergence of the light.

[0041] Specifically, the inner side wall of the light guide groove 165 can be provided with a chamfered or rounded structure, so that when the light is guided to the corner position of the light guide groove 165, the chamfered or rounded structure can be used to refract or diverge the light to guide the light to be smoothly guided out and reduce light dispersion.

[0042] Furthermore, in order to facilitate the detachable assembly of the panel 14 and the mounting port, a downwardly extending hook 141 may be further provided at the bottom end of the panel 14, and a corresponding bayonet 163 may be provided on the inner wall of the light guide cover 16. In this way, when the panel 14 is sealed to the mounting port, the hook 141 may be extended into the mounting cavity and correspond to the bayonet 163 of the light guide cover 16.

[0043] Of course, the above-mentioned hook 141 can be provided in plurality, and the corresponding bayonet 163 can also be provided in plurality. The plurality of hooks 141 and the plurality of bayonet 163 are provided in one-to-one correspondence, so that the structure of the panel 14 is more stable after assembly.

[0044] Furthermore, a plurality of limiting ribs 142 may be provided on the inner peripheral wall of the panel 14. After the panel 14 is sealed to the installation opening, since the panel 14 is located above the speaker assembly 40, if the panel 14 is directly close to the end face of the speaker assembly 40, it will affect the sound effect of the speaker assembly 40. In this embodiment, the panel 14 is spaced from the speaker assembly 40 after assembly, and the hook 141 extends downward into the bayonet 163 below the light guide cover 16, and the limiting ribs 142 on the inner peripheral wall of the panel 14 are pressed against the top peripheral edge of the speaker assembly 40, so that the panel 14 and the speaker assembly 40 are kept apart and the sound of the speaker assembly 40 is not affected. At the same time, the plurality of limiting ribs 142 are pressed against the edge of the speaker assembly 40 to prevent the speaker assembly 40 from shaking and detaching, so that the assembly structure is more stable.

[0045] Furthermore, on the basis of setting the structure of the light guide cover 16, in order to facilitate the electrical connection between the speaker assembly 40 and the circuit board 20, a threading hole 164 can be provided at the bottom end of the light guide cover 16. The threading hole 164 can guide the power cord of the speaker assembly 40 to be electrically connected to the circuit board 20.

[0047] During assembly, the circuit board 20, light source assembly and other structures can be pre-installed on the base 12, and then the light guide cover 16, speaker assembly 40 and other structures can be assembled in the top shell 11, so that the top shell 11 and the base 12 can be assembled, which is convenient for disassembly and assembly of the internal structure of the shell. After the assembly is in place, the panel 14 can be sealed to the installation port of the top shell 11.

[0048] Of course, the assembly of the top shell 11 and the base 12 can be achieved by means of a screw structure, a snap-fit ​​structure, or gluing.

[0049] Furthermore, in the present embodiment, a first step surface and a first limiting edge 111 may be provided on the periphery of the top shell 11, and the first step surface is located on the outside of the first limiting edge 111, and a second step surface 122 and a second limiting edge 121 may be provided on the periphery of the base 12, and the second step surface 122 is located on the inside of the second limiting edge 121. In this way, when the top shell 11 and the base 12 are assembled, the bottom end of the top shell 11 may be sealed above the base 12, and the first limiting edge 111 may be inserted on the inside of the second limiting edge 121, and the first limiting edge 111 abuts against the second step surface 122, and the second limiting edge 121 abuts against the first step surface. After the assembly is completed, the first limiting edge 111 and the second limiting edge 121 form a mutually abutting structure, and the first step surface, the second step surface 122 are assembled against the corresponding limiting edges, and the structure is more stable after assembly.

[0050] Furthermore, the light source assembly includes a plurality of lamp beads 30, and the plurality of lamp beads 30 are all disposed on the circuit board 20, so that the plurality of lamp beads 30 can be dispersedly distributed on the circuit board 20, so that the light distribution can be uniform.

[0051] It should be noted that the above-mentioned lamp beads can be implemented by using structures such as LED lamp beads or light strips in the prior art.

[0052] In addition, a plug-in piece 15 is provided at the bottom end of the shell, and the plug-in piece 15 extends into the installation cavity and is electrically connected to the circuit board 20, so that the door structure can be electrically connected to the external socket through the plug-in piece 15 to achieve power supply.
