Description
TECHNICAL FIELD

Embodiments are generally related to consumer electronics. Embodiments are also related to doorbells and door chimes. Embodiments are further related to electronic doorbells and door chimes. Embodiments also relate to doorbell and door chime installation.


BACKGROUND

Prior art doorbell design is antiquated. Old doorbells had a transformer, a switch (doorbell), and a sonic transducer (chime, ringer, or buzzer). Closing the switch completed the circuit powering the sonic transducer. Some doorbells have been upgraded with electronic door chimes. Electronic door chimes can be powered, similar to the mechanical ringers of old, when the switch is closed, and the electronic door chime receives power. An advantage of electronic door chimes is that they can generate more, and different doorbell sounds and have been cost effective replacements for broken mechanical ringers.


IOT devices are internet connected sensors and actuators. An IOT doorbell can trigger a message to a person's smart phone or other internet connected device. Some IOT doorbells now include security cameras allowing a person to remotely monitor the happenings outside their door. As many people have discovered, these IOT doorbells are not always compatible with existing doorbells.



FIGS. 1 and 2, labeled as prior art, illustrate an electronic door chime that has enjoyed wide market acceptance and bears “UL” markings because it has been assessed as safe by UL, formerly Underwriters Laboratories. Those practiced in consumer electronics and product development know that an electronic door chime lacking UL certifications will not be approved for sale by most U.S. retailers or for installation by licensed contractors or home builders. UL 94 and UL 746 specify testing protocols and the classifications that may be applied to plastic materials.


UL 746 testing can establish “RTI” (Relative Temperature Index″) ratings for materials. RTI is the maximum service temperature for a material where a class of critical properties will not be unacceptably compromised through chemical thermal degradation. This spans over the reasonable life of an electrical product relative to a reference material having a confirmed, acceptable corresponding performance defined RTI. RTI electrical is electrical RTI and is associated with critical electrical insulating properties. RTI impact is mechanical impact RTI and is associated with critical impact resistance, resilience, and flexibility properties. RTI strength is mechanical strength RTI or mechanical without impact and is associated with critical mechanical strength where impact resistance, resilience and flexibility are not essential. Those familiar with product certifications are familiar with RTI electrical, RTI impact, and RTI strength.


There are 12 UL 94 specified flame classifications assigned to materials based on the results of these small-scale flame tests. These classifications, listed in descending order for each of three groupings, distinguish a material's burning characteristics after test specimens have been exposed to a specified test flame under controlled laboratory conditions. The six of the classifications of interest here relate to materials commonly used in manufacturing enclosures, structural parts and insulators found in consumer electronic products (5 VA, 5 VB, V-0, V-1, V-2, HB). The classifications are listed in order from highest (most flame retardant) to lowest (least flame retardant) with 5 VA higher than 5 VB, 5 VB higher than V-0, etc.



FIG. 1, labeled as prior art, illustrates an exploded view of an electronic door chime 101. The electronic door chime 101 can be installed in a two-gang dual voltage junction box 108. The sizes of junction boxes are often specified by the number of “gangs” which is the number of standard sized wired devices the box can accommodate. As electricians know, junction box sizes have standardized sizes as specified by the National Electric Code (“NEC”). A single gang junction box is approximately 2″×4″ with varying depth. A dual voltage two-gang junction box has two single-gang sections and a solid wall between the two sections to thereby isolate one section from the other.


A back piece 107 has a first compartment 127 and a second compartment 128. When installed in the dual voltage junction box, the compartments are on different sides of the solid wall with the first compartment in one section and the second compartment in the other. A transformer 106 is held in the first compartment 127 by screws 111. A circuit board 105 is held in the second compartment by screws 110. A speaker 104 in the first compartment is electrically attached to the circuit board 105. A faceplate 102 is held to the back piece 107 by screws 112 that pass through spacers 114 and thread into the faceplate 102. The spacers 114 are molded into the back piece 107. The illustrated electronic door chime 101 can be wired to two doorbell buttons 109. Two two-wire busses 113 attach the doorbell buttons 109 to the electronic door chime 101. The electronic door chime 101 can produce one sound when one of the doorbell buttons 109 is pressed and a different sound when the other doorbell button 109 is pressed.



FIG. 2, labeled as prior art, illustrates a transformer 106 and circuit board 105 in an electronic door chime 101. The spacers 114 can be seen extending into the compartments 127, 128.


The electronic door chime 101 of FIGS. 1 and 2 show a commercially successful unit at least in part because it is one of the few such devices that has surpassed safety standards and carries UL safety markings.


While these advantages are noteworthy, in order to meet the safety standards, prior art chimes must be installed in dual gang boxes. Systems and methods for electronic door chimes that are compatible with current generation IOT doorbells, and that are certified as safe for installation in single-gang boxes are needed.

FIG. 3A illustrates an exploded view of a door chime and housing system 300 configured to be installed in a single-gang box, in accordance with the disclosed embodiment. The door chime housing includes a front cover 305, with front grate 310 in the front face 315 to allow sound to exit the housing 300. The front cover 305 further includes two screw holes 320 that allow a screw to connect the front cover 305 to the remainder of the housing.


A speaker element 340, can comprise a loudspeaker or other such sound producing system, and can be configured to connect to a printed circuit board (PCB) 345 below the front cover 305. The remainder of the housing 300 includes a bottom cover 325 configured to house the PCB 345 and speaker element 340. The front cover 305 and bottom cover 325 can be joined together with any fastening means, or can be configured to snap together.



FIG. 3B illustrates additional aspects and embodiments of the door chime and housing system 300. In certain embodiments, the bottom cover 325 can be designed to fit in a box 330, which can comprise a single-gang remodel voltage box, or the like. A separation board 335 can extend from the back 350 of the bottom cover 325, into the box 330. The separation board can separate the AC input (e.g., 120 VAC) side 355 of the box 330, from the output side 360 of the box 330. This constructions allows UL Class 1 and Class 2 wiring in the same wiring box, separating the high voltage and low voltage. The separation board 335 can be configured to include at least one, and potentially multiple, breaking scores 336 so that the separation board 335 can be sized to fit into different sized wiring boxes 330. The separation board can be made in accordance with the UL94 fire retardant standard.



FIG. 3C illustrates a cross-sectional view of a door chime and housing system 300. The bottom cover 325 can include one or more holes 370 configured to accept one or more pegs 371 attached to a separation board 335. FIG. 3D illustrates a cross-sectional view of an alternative embodiment of door chime and housing system 300. In this embodiment, the bottom cover 325 can include one or more holes 370 configured to accept one or more pegs 371 attached to a separation board 335.


It should be appreciated that the disclosed system 300 can be configured to be installed in a single gang wall box (such as box 330) as illustrated. This allows the system 300 to be installed in virtually any location including during a remodel or renovation, without the need for a dual gang, dual-voltage wall box, as is required for prior art technologies. This is made possible by, among other things, the separation board 335, which is configured to separate higher voltage input side 355 and output side 360. In FIG. 3C the separation board 335 is configured to be arranged closer to the high voltage input side 355. In FIG. 3D the separation board is configured to be arranged closer to the output side 360.



FIG. 3E and FIG. 3F illustrates further aspects of the system 300. FIG. 3C illustrates input lines 375 entering bottom cover 325 through input holes 380. Likewise, output connections 385 are illustrated on the bottom cover 325. The output connections can comprise sockets for connecting the PCB and loudspeaker to an external circuitry.


In certain embodiments, the components of the door chime can meet UL approval. For example, the conductors can be rated for the highest potential of the Class 1 circuit. Termination for the Class 2 conductors can be recessed, as shown. A UL recognized terminal block, suitable for field wiring, can be used for certain applications (e.g., a screwless type is acceptable). The connectors can comprise spring clip types with a button on each connector positioned to release the wire. In other embodiments the connections can be hard wired.


In certain embodiments, the system 300 can include a line powered doorbell button 400, as illustrated in FIG. 4A. In this embodiment, the doorbell button can include a door chime key 405 configured in a housing 410. A PCB 415 can be connected to line power. The wired button can further include a back cover 420 with two mounting holes. Schematics of associated circuits are further detailed herein.


In certain embodiment, the system 300 can include a line powered doorbell button 450, as illustrated in FIG. 4B. In this embodiment, the doorbell button can include a door chime key 455. The door chime key can comprise a round key configured to fit through a round faceplate 460. The round faceplate 460 and or the door chime key can be stylized with a desired finish. A PCB 465 can be connected to line power. The wired button can further include a housing tube 470 configured to be embedded into wall, for example, before stucco is applied to the wall.



FIG. 5 illustrates a block diagram of a low power wired chime kit 500 in accordance with the disclosed embodiments. In certain embodiments the low power wired chime kit can comprise a 5 W wired chime kit. In other embodiments, other powers are possible. The wired chime kit 500 includes a switching power supply circuit 505 operably connected to a chiming circuit 510, and two terminals, first terminal 515 and second terminal 520.


A traditional mechanical transformer is a “linear” component to the circuit, it steps down voltage for the doorbell mechanically, when there's surge from the main or caused by the doorbell's power consumption change, traditional mechanical transformer won't be able to filter or absorb surge, which may hurt or damage the doorbell. The electronic switching power supply circuit 505 can have an output of constant 24 VDC power (or other such level), which is more stable. The electronic switching power circuit 505 also provides additional protection functions including but not limited to surge protection and power limiting, as well as providing the doorbell with extra protection.


Thus, the electronic switching power supply circuit has multiple benefits to the doorbell sensor circuit. For example, it offers a more stable and safe current input to the doorbell sensor because the current input is DC instead of DC. The switching power supply protects the doorbell sensor from unexpected surges, where a traditional mechanical transformer doesn't. The switching power supply's output DC current is an impulse current due to its switching on/off working mode, the impulse DC current helps improve the doorbell sensor's temperature and life. In addition, it adds a level of safety for unusual circumstances, for example, when the doorbell's button is pressed or held for long time without being released to its normal open position.


The two terminals 515 and 520 connect to the wired button. The switching power supply circuit is further connected to a signal sampling circuit 525. The chiming circuit 510 is connected directly to the speaker 530, such that operation of the wired button results in an audible sound output by the speaker 530.

The method comprises attaching a power supply to a back cover, the power supply configured to receive mains electric power and to produce a DC output, attaching a first circuit powered by the AC input to the back cover, the first circuit comprising a power section, a doorbell interface, a doorbell sensor, and a chiming circuit, forming a housing by attaching a front cover to the back cover, the back cover comprising a separation board, and the housing configured for installation in a single-gang voltage box, receiving a doorbell trigger signal, sending a trigger sensed signal to the chiming circuit in response to receiving the doorbell trigger signal, and producing a sound wherein the chiming circuit sends a sound signal to a speaker held between the front cover and the first circuit to thereby cause the speaker to produce sounds. The method can comprise attaching a faceplate to the front cover, the faceplate configured to cover the housing when the housing is installed in the single-gang voltage box.



FIG. 18 illustrates steps associated with such a method 1800 in accordance with the disclosed embodiments. The method 1800 illustrates configuration and use of an electronic door chime as disclosed herein. The methods starts at 1805.


At step 1810, a power supply can be attached to the back cover. The power supply is configured to receive mains electric power and to produce a DC power output. Next at step 1815, a first circuit powered by AC output can be attached to the back circuit. The first circuit can have a power section, doorbell interface, doorbell sensor, and a chiming circuit.


At step 1820, a housing is formed by attaching the front cover to the back cover. The back cover has a compartment, as well as a separation board configured to separate the voltage box. The power supply is isolated, by the separation board, from low voltage components. The housing is ready for installation in a single-gang voltage box.


Now, at 1825 a first DC output and a second DC output are produced from the AC input. The first DC output and the second DC output are at different voltages. An external doorbell device (e.g., a doorbell button) is continuously provided power from the power section, with at least 18 VDC at 500 mA or more at step 1830. The external doorbell device produces a doorbell trigger signal when a doorbell button is actuated. Likewise, at 1835, the doorbell sensor is continuously powered by the first DC output. The chiming circuit is continuously powered from the second DC output at step 1840.


In response to receiving the doorbell trigger signal at step 1845, a trigger sensed signal is sent to the chiming circuit at step 1850. An audible sound is produced by a speaker connected to the chiming circuit because the chiming circuit sends a sound signal to the speaker in response to receiving the trigger sensed signal as illustrated at 1855. The method ends at 1860.


As such, in certain embodiments the method comprises attaching a power supply to a back cover, the power supply configured to receive mains electric power and to produce an DC output, attaching a first circuit to the back cover, the first circuit comprising a power section, a doorbell interface, a doorbell sensor, and a chiming circuit, forming a housing by attaching a front cover to the back cover, the back cover comprising a separation board, and the housing configured for installation in a single-gang voltage box receiving a doorbell trigger signal, sending a trigger sensed signal to the chiming circuit in response to receiving the doorbell trigger signal, and producing a sound wherein the chiming circuit sends a sound signal to a speaker held between the front cover and the first circuit to thereby cause the speaker to produce sounds. The method can further comprise attaching a faceplate to the front cover, the faceplate configured to cover the housing when the housing is installed in the single gang voltage box. The method can further comprise producing a rectified output, powering a light emitting diode from the rectified output only when a switch is open, and producing the doorbell trigger signal when the switch is closed. The method can further comprise producing a rectified output, powering a light emitting diode from the rectified output only when a switch is closed, and producing the doorbell trigger signal when the switch is closed.



FIG. 19A illustrates a low power circuit assembly 1900 that can be used in certain embodiments, in place of the circuit assembly 600. The circuit assembly 1900 provides a melody selection function, so that the melody associated with the chime can be selected from several options. The circuit assembly 1900 includes a switching power circuit 1905, a terminal circuit 1910, a module interface 1915, and a chiming circuit 1920.



FIG. 19B illustrates a high power circuit assembly 1950 that can be used in certain embodiments, in place of the circuit assembly 900. The circuit assembly 1950 provides a melody selection function, so that the melody associated with the chime can be selected from several options. The circuit assembly 1950 includes a switching power circuit 1955, a 5V power supply circuit 1960, a terminal circuit 1965, a module interface 1970, and a chiming circuit 1975.



FIG. 20, illustrates steps associated with a method 2000, associated with the steps for selecting a melody in accordance with circuit assembly 1900 or circuit assembly 1950, in combination with other systems and methods disclosed herein. The method begins at 2005.


At step 2010, a button associated with the circuit can be pressed and held for more than 3 seconds. This will enter the melody selection mode. An associated indicator light will appear on and a chime will play. The chime can include an audio queue indicating the mode is for setting the chime melody for the front door. As illustrated by dotted line 2007 if any of the subsequent steps are not taken within a given amount of time, the system exits the melody selection mode at step 2035 and the method ends.


If, within 20 seconds, the button is pressed again, this time with a short press of less than 3 seconds, the system will cycle through available chime melodies as shown at step 2015. With each short press a new candidate melody is played.


Once a candidate melody is selected as the desired melody for the front door, within 20 seconds of the chime for that melody playing, the melody can be confirmed with a long press of greater than 3 seconds as shown at step 2020. If a second doorbell is available, the system will immediately proceed to the identical procedure for setting the second door melody. An audio queue can prompt that the mode is for setting the chime melody for the second door.


At step 2025, short button presses of less than three seconds can cycle through candidate second door melodies. With each short press the chime will play the candidate melody for the second door. Once a candidate melody is selected as the desired melody for the second door, within 20 seconds of the chime for that melody playing, the melody can be confirmed with a long press of greater than 3 seconds as shown at step 2030.


Both the front door and second door melodies have been set at step 2035. The indicator light turns off and the system exits the melody selection mode.
