• short answer beep will not work under android since android doesn't have an internal system speaker and no kernel module pcspkr , I tried to beep old school way with the command echo -en "\a" > /dev/tty5 but it will not work since android doesn't have an internal speaker.

• when ever I run beep with root or without it nit always return the same error

  beep : can't open console after reading the beep documentation I think the problem is not that you don't have permission but due to
  

  beep command not finding the console (for info beep will use tty0 as default console to beep and not the /dev/console) and that's why it returns can't open console and not "permission denied" to fix this you gonna need to compile beep from busybox source with option to change the default console like in the beep desktop version.

• But nothing is impossible you can make your own beep program easily following this steps :

• make sure you have the binary aplay on your phone have it under /system/bin it is used by the system to play boot sounds if you don't have it grab the arm version from here and put it under /system/bin on your phone and give it the right permission it have to be executable.

• download this beep.wav file from here and put it somewhere on the system partition of the phone or any where else your choice in my exemple it will be /system/beep.wav.

• now you can either beep usin this command

  aplay /system/beep.wav

or you can make a script file name it beep and put it under /system/xbin or /system/bin you can either over right or rename the old copy since it is just a simlink or the busybox binary you can always call the original beep by busybox beep command and don't forget to give it the execute permission  . here is the simple exemple of the script you write

this will beep your device with the current default speaker it can be the phone's speaker  ,headset or Bluetooth headset  ,you can change that using the aplay option -Dnameofpcmdevice

this script can only beep once but  ,I see many possibilities can be added easily  ,like playing other sounds alarm and adding arguments like frequency..ect

Short answer:

beep will not work under Android as Android devices do not have an internal system speaker and no kernel module pcspkr. I tried to beep old school way with the command echo -en "\a" > /dev/tty5, but it will not work since Android doesn't have an internal speaker.

Whenever I run beep with root or without it always return the same error:

   beep : can't open console

After reading the beep documentation I think the problem is not that you don't have permission – but due to beep command not finding the console (for info: beep will use tty0 as default console to beep and not the /dev/console) and that's why it returns "can't open console" and not "permission denied". To fix this you would need to compile beep from busybox source with option to change the default console like in the beep desktop version.

But nothing is impossible you can make your own beep program easily following this steps :

• make sure you have the binary aplay on your phone have it under /system/bin it is used by the system to play boot sounds if you don't have it grab the arm version from here and put it under /system/bin on your phone and give it the right permission it have to be executable.

• download this beep.wav file from here and put it somewhere on the system partition of the phone or any where else your choice in my exemple it will be /system/beep.wav.

• now you can either beep usin this command

   aplay /system/beep.wav
  

or you can make a script file name it beep and put it under /system/xbin or /system/bin you can either over right or rename the old copy since it is just a symlink to the busybox binary. You can always call the original beep by busybox beep command and don't forget to give it the execute permission.

Here is the simple exemple of the script to write:

This will beep your device with the current default speaker it can be the phone's speaker, headset or Bluetooth headset, you can change that using the aplay option -Dnameofpcmdevice

This script can only beep once but, I see many possibilities can be added easily, like playing other sounds alarm and adding arguments like frequency – and much more.
