Cell phone speaker element use

Ken wa4mnt All Messages By This Member #120492 Most cell phone speakers sound pretty good for their size. Does anyone have any experience using a speaker out of a defunct cellphone for projects? ken -wa4mnt
Dave VE3GSO All Messages By This Member #120493 开云体育 Hi Ken I have used tiny oval speakers out of laptops. These are modular back sealed units and sound not too bad. Four ohm so a 386 does not get too loud, but that’s OK. ?Keeps peace in the family.

Daniel Holmes All Messages By This Member #120494 开云体育 That’s an interesting idea. I wonder how well that would work. I have a feeling that they sound good due to sound tunnels and such in the phones. But certainly worth a shot, they are designed for big sound with an efficient power draw.? Dan -- . Please pardon any mispelings or errors. toggle quoted message Show quoted text On Apr 6, 2024, at 9:01?AM, Ken wa4mnt <wa4mnt@...> wrote: ?Most cell phone speakers sound pretty good for their size.

Graham Whaley All Messages By This Member #120495 开云体育 yep, I strongly suspect not only do they rely on the precise hardware layout inside the phone, but they will be driven with some quite serious waveform shaping (equalisation etc) in order to cater for their most likely very non-flat frequency response. ?So do not be surprised if they sound pretty bad once extracted from a phone ;-) Graham, M7GRW toggle quoted message Show quoted text On 6 Apr 2024, at 16:11, Daniel Holmes <danielh@...> wrote: ?That’s an interesting idea.

Those that have built in mounting (laptop) are less fussy but cellphone speakers the case is part of the acoustic package. They do have a significant size advantage.? Really helps if small is important. -- Allison ------------------ Post online only,? direct email will go to a bit bucket.
