DETAILED DESCRIPTION

(8) Disclosed herein are methods, systems, devices, and/or vehicles for implementing a portable speaker security system. Particular embodiments of the subject matter described in this disclosure may be implemented to realize one or more of the following advantages. The portable speaker security system may prevent the unauthorized taking and/or theft of a portable speaker included with and/or located within a vehicle. The portable speaker security system may monitor an electrical connection between the portable speaker and a speaker dock located within the vehicle to determine whether the portable speaker has been removed from the speaker dock. To monitor the electrical connection, a sensor of the portable speaker security system may continuously determine, measure, and/or detect an impedance of the portable speaker. The portable speaker security system may indicate a disconnect in the electrical connection based on the impedance of the portable speaker. When the disconnect is indicated, the portable speaker security system may transmit a message to one or more user devices to notify a user (i.e., an owner and/or authorized user of the vehicle) that the portable speaker has been disconnected from the speaker dock. Hence, the portable speaker security system can advantageously determine if the portable speaker has been misplaced or not on or properly connected to the speaker dock.

(9) Moreover, the portable speaker security system may activate an alarm of the vehicle when the disconnect is indicated to stop the theft of the portable speaker and/or to notify people within the surrounding area of the vehicle to enhance security of the portable speaker. In examples, the message transmitted to the one or more user devices may provide the user an option to activate and/or deactivate the alarm. In the same and/or additional examples, the message may further include an option to notify the police of the theft of the portable speaker and provide the police with a current location of the vehicle and/or a current location of the portable speaker.

(10) Moreover, the portable speaker security system may further enhance security of the portable speaker by including one or more cameras that may record images and/or video of an area within a cabin of the vehicle and/or a surrounding area of the vehicle when the disconnect is indicated. The images and/or the video may track one or more persons running away from the vehicle after the theft has been detected. The images and/or the video may be included in the message that is transmitted to the one or more user devices. The images and/or the video may assist the user and/or the police by showing what happened and/or who removed the portable speaker from the vehicle.

For example, the user may set the portable speaker security system 100 to activate, via the ECU 106, the alarm device 136 when the disconnect is indicated. In another example, the user may set when the portable speaker security system 100 is active (i.e., monitoring the electrical connection between the dock 105 and the portable speaker 104). The user may set the portable speaker security system 100 to be active, for example, when the vehicle 102 is locked and/or when a key (e.g., a key card, a key fob, a mobile phone acting as a key, etc.) is not detected by the ECU 106 and/or within a predetermined range (e.g., 5 feet, 10 feet, 20 feet, etc.) of the vehicle 102. The user interface 110 and/or the one or more user devices 142 may further enable the user to enter a passcode to deactivate the portable speaker security system 100 and/or prevent the message from being transmitted to the one or more user devices 142 such that the user may remove the portable speaker 104 from the dock 105 without activating the portable speaker security system 100 and/or the alarm device 136. In examples, the user interface 110 and/or the one or more user devices 142 may further prompt the user to enter the passcode to deactivate the alarm device 136 after the alarm device 136 has been activated.

(31) FIG. 5 is a flow diagram of an example process 500 for monitoring and/or securing a portable speaker of a vehicle. One or more computers or one or more data processing apparatuses, for example, the ECU 106 and/or the microcontroller 122 of the portable speaker security system 100 of FIG. 1, appropriately programmed, may implement the process 500. For ease of description, the process 500 is described below with reference to FIGS. 1, 2A, 2B, 3, and 4. The process 500 of the present disclosure, however, is not limited to use of the exemplary portable speaker security systems of FIGS. 1, 2A, 2B, 3, and 4.

(32) The portable speaker security system 100 may detect and/or monitor, via the impedance sensor 109, an impedance reading of the portable speaker 104 electrically connected to the dock 105 (502). The impedance sensor 109 may output the impedance reading (or impedance data) corresponding to the impedance of the portable speaker 104 and/or the impedance between the one or more terminals 304 to the ECU 106 and/or the head unit 120.

(33) The portable speaker security system 100 may indicate (e.g., via the ECU 106 and/or the head unit 120) a disconnect between the portable speaker 104 and the dock 105 when the impedance reading is greater than a threshold (or impedance threshold) (504). The threshold may be predetermined and may be stored in the memory 108. The threshold may be 1-500 ohms (or another impedance that corresponds to the portable speaker 104 being in the docked state 208 and electrically connected to the dock 105).

(34) In response to the disconnect being indicated, the portable speaker security system 100 may activate the alarm device 136 of the vehicle 102.

(35) The portable speaker security system 100 may transmit, via the network access device 114 a message (or information) to one or more user devices 142 (e.g., a phone of an owner of the vehicle 102) indicating the portable speaker 104 has been disconnected from the dock 105 (508). In examples, the message may include a user selectable option indicating the disconnect was unauthorized, with the alarm device 136 being activated upon, and not before, the portable speaker security system 100 receiving, via the network access device 114, data from the one or more user devices 142 indicating the disconnect was unauthorized (i.e., the user selectable option was selected by the user). In the same or additional examples, after receiving the data from the one or more user devices 142 indicating the disconnect was unauthorized, the portable speaker security system 100 may transmit another message to police indicating the portable speaker 104 has been stolen and indicating, via the navigation unit 118, a current location of the vehicle 102. In the same or additional examples, the message may include another user selectable option indicating the disconnect was authorized. When the another user selectable option is selected by the user, the portable speaker security system 100 may deactivate the alarm device 136 if the alarm device 136 has been activated and/or may prevent the alarm device 136 from being activated.

(36) In examples, the portable speaker security system 100 may stop and/or prevent the message from being transmitted to the one or more user devices 142 when a key of the vehicle 102 is detected by the vehicle 102 and/or within a predetermined distance from the vehicle 102.

(37) In examples, when the disconnect is indicated, the portable speaker security system 100 may record, via the one or more cameras 138, one or more images and/or one or more videos of the area within the cabin 202 of the vehicle 102 and/or the surrounding area of the vehicle 102 (510).

(38) In examples, the portable speaker security system 100 may further transmit, via the network access device 114, the one or more images and/or the one or more videos to the one or more user devices 142 (512).
