Description
A BABY ALARM WITH A COMBINED CHARGING AND TRANSMITTINGUNIT Technical FieldThe present invention relates to a baby alarm. In particular, the presentinvention relates to a baby alarm having a transmitting unit and a portable receiving unit.
BackgroundBaby alarms are increasingly popular. In general, the baby alarm includes a transmitter unit that is supposed to be positioned close to the baby to bemonitored, and a receiver unit being positioned at a remote location. Amicrophone of the transmitter unit is used to collect sound from the baby and totransmit the sound to the receiver unit, so that a person being responsible forcaring for the baby and carrying or being close to the receiving unit is alerted bythe receiving unit producing the sound or making another indication of the sound.While the transmitter unit can be operated while plugged into mainspower, the receiver unit is normally powered by a battery. As the number ofbattery powered home appliances is steadily growing, there is a risk that chargingis forgotten especially for devices not used and/or charged on a daily basis, suchas baby alarms. Such devices are also easily lost because ofthe time periodsbetween use.Hence, there is a need for a baby alarm which mitigates the above- mentioned drawbacks.
SummaryIt is therefore an object of the invention to at least partly overcome one or more of the above-identified limitations of the prior art. In particular, it is anobject to provide a baby alarm, as well as a transmitting unit and a receiving unitfor such baby alarm.
An idea of the present invention is to invite the user to always charge thereceiving unit close to the transmitting unit, so that the receiving unit is easilyfound when needed. A further idea of the present invention is to reduce thenumber of charging devices needed.
In a first aspect, a baby alarm is provided. The baby alarm comprises atransmitting unit and a receiving unit configured to receive and produce sound transmitted from the transmitting unit. The transmitting unit and the receiving unit comprises respective matching charging connectors such that When the twocharging connectors are connected to each other, the transmitting unit acts as acharger for the receiving unit.
The charging connector of the transmitting unit is provided on a topsurface ofthe transmitting unit. Hence, the receiving unit can be placed on top ofthe transmitting unit, thereby making it clearly visible and easy to localize. Ars ln combination thereWith, the charging connector of thetransmitting unit na-a-y=bei_s arranged in a recess of the transmitting unit. Therebyprotection against mechanical damage to the charging connector may beachieved. Furthermore, the recess may also contribute to keeping the receivingunit in a desired position during charging.
The top surface ma-yßbeis inclined thereby forming a recess. The recessmay form a receptacle for receiving at least portions of the receiving unit duringcharging ofthe latter. The recess Will form a receptacle for the receiving unit,thereby ensuring that the receiving unit remains at its charging position.
The charging connector of the transmitting unit may be provided at abottom portion of the recess. Hence, it is further ensured that the receiving unit isarranged at its desired charging position relative the transmitting unit.
The receiving unit may comprise an arrangement for detecting proximityto the transmitting unit, the receiving unit being arranged for interrupt producingsound When being in a determined proximity to the transmitting unit. Thereby,acoustic feedback can be avoided When the transmitting unit and the receivingunit are located close to each other, such as being located in the same room, andalso in the event the receiving unit being located on the transmitting unit forcharging.
The receiving unit may be arranged to automatically enter a stand-bymode When put on the transmitting unit for being charged. Such stand-by modemay include no production of sound and/or minimal battery consumption. Thisprovides for a simple and efficient Way of reducing battery consumption and/oracoustic feedback.
The receiving unit may be arranged for automatically resumingproduction of sound When being detached from the transmitting unit. Thisreduces the risk of a user forgetting to activate the receiving unit after beingcharged. Such resumption of production of sound being resumed after a Waitingtime, such as a Waiting time of 1-20 seconds. Such Waiting time has theadvantage of reducing the risk of a baby being Woken up by acoustic feed-back When a user picks up the receiving unit from the transmitting unit.
According to one embodiment the transmitting unit is arranged to chargethe receiving unit with low voltage, such as maximum 5 Volts. Thereby, the riskof a baby coming into contact with the charging connectors and receiving anunpleasant electric shock is reduced.
According to a second aspect, a transmitting unit of a baby alarm isprovided. The transmitting unit comprises a charging connector configured to beconnected to a corresponding charging connector of an associated receiving unit,wherein the charging connector of the transmitting unit is configured such thatwhen the charging connectors are connected, the transmitting unit acts as a charger for the receiving unit. The charging connector of the transmitting unit is provided on a top surface of the transmitting unit, and the top surface is inclinedtherebv forming a recess, preferablv said recess forming a receptacle forreceiving at least portions of the receiving unit during charging of the latter,more preferablv the recess being arranged for holding the receiving unit duringcharging thereof.
According to a third aspect, a receiving unit of a baby alarm is provided.The receiving unit comprises a charging connector configured to be connected toa corresponding charging connector of an associated transmitting unit accordingto the second aspect.

The receiving unit 30 has an essentially planar bottom surface,and a curved periphery being dimensioned to fit inside the recess 24 (see Fig. l)of the transmitting unit 20. Preferably, the receiving unit 30 has the shape of acircular puck that in addition to being easy to fit inside the recess 24 also fitswell, when in use, in the pocket of a pair oftrousers, the pocket of a jacket, or asmall handbag. Due to the planar bottom of the receiving unit 30, and theinclined top surface 23 of the transmitting unit 20, the receiving unit 30 will beurged towards a position where it rests against the peripheral walls of thetransmitting unit 20. At this position, a charging connector 35 g of the receivingunit 30 is in contact with the charging connector 25g of the transmitting unit 20in order to allow for charging ofthe receiving unitThe receiving unit 30 is provided with an on/off switch 35a, arranged onthe outer periphery ofthe receiving unit 30. The on/off switch 35a is preferably awheel which also acts as a volume control. As for the microphone sensitivitycontrol of the transmitting unit 20, the volume control can be step-less orseparated into distinct levels, such as between l andThe receiving unit 30 also comprises an input connector 35b for an associated external charger, preferably implemented as a USB-C connector. A battery indicator 35d is also provided, preferably configured to indicate i) poweron and fully charged, ii) charging, and iii) low battery. Indication of thesedifferent status can e.g. be done by colour change and/or flashing.
Yet further, a receiving indicator 35e is provided for notifying whenreceiving and picking up sound. Also, a speaker 35fis provided, a microphone(not shown), and a talk button 35h. When depressed, the receiving unit 30 willact as a transmitter, transmitting sound to the baby unit (i.e. the transmitting unit20). As for the transmitting unit 20, the receiving unit 30 further comprises allnecessary electronic equipment which will not be described further herein.
As explained above, the receiving unit 30 can be charged using anexternal charger connected to by means of a power cable, or it can be charged bydocking into the transmitting unitOptionally, the receiving unit 30 is configured to sense that it is close(e. g. within 2 meters) of the transmitting unit 20, and upon such detection it isfurther configured to automatically shut off its speaker, to avoid acousticfeedback. Optionally, as alternative to or in combination with the abovedescribed sensing of closeness to the transmitting unit 20, the receiving unit 30may be arranged for automatically shutting off its speaker when put on thetransmitting unit 20 for charging, to reduce power consumption and reduceacoustic feedback. When the receiving unit 30 is removed from the transmittingunit 20 (e.g. after charging) sound transmission is delayed for a predeterminedtime, e.g. 2 seconds after such removal, also for avoiding acoustic feedback.
