Description

Technical Field

[0001] This utility model belongs to the field of mobile phone case technology, and specifically relates to a Bluetooth voice intercom mobile phone case. Background Technology

[0002] The pure software-based PTT (Push-to-Talk) app captures voice through the phone's microphone and uploads it via cellular / Wi-Fi networks; voice is initiated by clicking a virtual button on the touchscreen interface. Not only is the operation process lengthy—turning on the screen → unlocking → entering the app → triggering the virtual button—the steps are rather cumbersome; but it also lacks physical buttons, making it difficult to perform voice conversations by blind operation.

[0003] In existing technologies, the "micro-speaker intercom" software achieves blind operation voice intercom function by working with Bluetooth intercom buttons and Bluetooth multi-function side buttons. However, the Bluetooth intercom button is a separate component, which is easy to forget when placed casually. Using lanyards and straps makes it impossible to use with phone cases, and using adhesive backing makes it easy to leave glue marks, which is very inconvenient for disassembly and later replacement. At the same time, the Bluetooth communication method requires a relatively close distance to the mobile phone to ensure signal stability. All of these reasons limit the development of Bluetooth intercom function. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a Bluetooth voice intercom phone case that is small in size and establishes a voice intercom link with a mobile phone APP through a Bluetooth module, enabling blind operation of voice intercom without clicking on the phone screen.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Please refer to Figures 1-12 This utility model provides a Bluetooth voice intercom phone case, including a phone case 1 and an intercom component 2 disposed on the back of the phone case 1. The intercom component 2 can be fixedly connected or magnetically connected. In this embodiment, the intercom component 2 is magnetically connected to the back of the phone case 1. A magnetic element 3 is embedded in the back of the phone case 1. This embedded design reduces the overall thickness and makes it more comfortable to hold. The intercom component 2 is provided with a magnetic element 4 that magnetically engages with the magnetic element 3. The two magnetic elements can be a combination of magnet + magnet or magnet + iron sheet. The magnetic element 4 protrudes slightly from the back of the phone case 1 for easy positioning during engagement. Furthermore, the magnetic engagement broadens the applicability of the intercom component 2, allowing it to be placed in other locations for connection and control via magnetic attraction.

[0037] The intercom component 2 has a built-in intercom button 201, a Bluetooth module, and a power supply module. The power supply module provides power to the Bluetooth module, which is electrically connected to the intercom button 201. Pressing the intercom button 201 controls the Bluetooth module to output command signals to the mobile APP to connect to the voice intercom module within the mobile APP. Additionally, function buttons can be integrated into the intercom component 2 to control functions such as voice message playback and mute.

[0038] The outer side of the intercom component 2 is equipped with a magnetic pull ring bracket 5. The magnetic structure allows the mobile phone to be fixed to the ferromagnetic bracket, without limiting the angle or position of the phone. An annular groove 203 is formed at the top outer edge of the intercom component 2, and the pull ring bracket 5 is embedded in the annular groove 203, concealing the pull ring bracket 3 within the intercom component 2. The bracket does not protrude from the intercom component 2, resulting in a smooth overall appearance. A charging port 202 is provided on the side wall of the intercom component 2, which is electrically connected to the power supply module.

[0039] The intercom button 201 is located at the center of the outer side of the intercom component 2. The center of the outer side of the intercom component 2 is entirely a pressable area, and it is engraved with an embossed design for easy finger placement, enabling blind operation. The intercom component 2 has a lanyard hole 6, allowing the phone to be placed directly in front of the chest after threading a lanyard, facilitating various usage scenarios and enabling quick responses while cycling. The intercom component 2 also has an indicator light 7 to display the device's status.

[0040] When in use, press the intercom button 201 in the center of the outer side of the intercom component 2. Pressing the intercom button 201 controls the Bluetooth module to output command signals to the mobile APP to connect to the voice intercom module in the mobile APP. This replaces the touch screen voice button, and the intercom function can be realized without clicking the mobile phone screen, simplifying the operation process of voice intercom and enabling blind operation.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
