Voice amplifier that amplifies a human voice from a microphone through a mobile device and internal speaker
View Patent ↗A voice amplifier that amplifies volume of a human voice from a microphone through a mobile device by utilizing a speaker that is communicably connected to the mobile device is disclosed. The voice amplifier is designed for a mobile device, such as a smart phone or a tablet computing device. The voice amplifier purely amplifies the voice from a wired or non-wired microphone through a phone operating system and hardware components and other modules of the mobile device, such as by utilizing the phone speaker and/or an optional wireless or wired speaker. Essentially through a voice amplifier mobile app, a voice can be amplified simply with the touch of one icon. The concept is for people wearing masks due to COVID-19 and future other viruses, and/or dusty, toxic, or otherwise unhealthy air environments where masks are needed, to continue to wear their mask but be able to communicate clearly.
1 . A voice amplification system comprising:
a mobile device comprising a speaker, a microphone, random access memory (RAM), a flash memory, a processing main control unit (MCU), radio-frequency (RF) hardware, and a microphone volume management module;
a voice amplifier mobile app that is stored in the flash memory of the mobile device and is executable by the MCU, wherein the voice amplifier mobile app, when executed by the MCU, is configured to:
receive, via the microphone of the mobile device or an external microphone coupled to the mobile device, voice sound waves generated by a user;
amplify the received voice sound waves in real-time with an undetectable delay; and
output the amplified voice sound waves through at least the speaker of the mobile device, wherein the RF hardware is configured to wirelessly couple the mobile device to an external speaker for output of the amplified voice sound waves.
2 . The voice amplification system of claim 1 , wherein the mobile device comprises a smartphone.
3 . The voice amplification system of claim 1 , wherein the mobile device comprises a tablet computing device.
4 . The voice amplification system of claim 1 , wherein the connected speaker comprises an internal speaker embedded in the mobile device.
5 . The voice amplification system of claim 1 , wherein the microphone comprises an internal microphone embedded in the mobile device.
6 . The voice amplification system of claim 1 , wherein the external speaker wirelessly coupled to the mobile device comprises an external speaker wirelessly connected to the mobile device.
7 . The voice amplification system of claim 6 , wherein the external speaker wirelessly connected to the mobile device comprises a group speaker.
8 . The voice amplification system of claim 1 , wherein the external microphone coupled to the mobile device comprises an external microphone wirelessly connected to the mobile device.
9 . A mobile device voice amplification method for amplifying voice sound waves, the method comprising:
displaying, on a touchscreen interface of a mobile device, an opening screen of a voice amplifier mobile app providing prompts for amplification setup;
determining whether an external microphone is connected to the mobile device;
prompting, when the external microphone is not connected, a user to connect an external microphone by a wired connection or a wireless connection;
receiving, via the external microphone or via an internal microphone of the mobile device, voice sound waves generated by the user;
receiving user input selecting a microphone icon or an on/off icon within the voice amplifier mobile app to initiate amplification;
amplifying the voice sound waves in real-time with an undetectable delay;
outputting the amplified voice sound waves through a speaker of the mobile device or through an external speaker wirelessly coupled to the mobile device;
orienting the mobile device such that the speaker is directed toward a listener; and
receiving, when finished amplifying the voice sound waves, a user input selection of the microphone icon or the on/off icon to stop the amplification of the voice sound waves.
10 . The mobile device voice amplification method of claim 9 , wherein displaying the opening screen view of the voice amplifier mobile app comprises prompting the user to perform a prerequisite action.
11 . The mobile device voice amplification method of claim 10 , wherein the prerequisite action comprises moving the external microphone close to a mouth of the user and instructing the user to start talking into the external microphone.
12 . The mobile device voice amplification method of claim 10 , wherein the prerequisite action comprises prompting the user to connect the external microphone by one of plugging in a hard wired microphone into the mobile device and wirelessly connecting a wireless microphone to the mobile device.
13 . The mobile device voice amplification method of claim 9 , wherein outputting the amplified voice sound waves comprises outputting the amplified voice sound waves in real-time through an external speaker.
14 . The mobile device voice amplification method of claim 13 , wherein the external speaker comprises a group speaker.
15 . The mobile device voice amplification method of claim 9 , wherein outputting the amplified voice sound waves comprises outputting the amplified voice sound waves in real-time through an internal speaker embedded in the mobile device.
