    In another thread, Bertus said,
    I have a speaker just mounted with a wire in my animatronic penguin. Taking Bertus' suggestion, does anyone have any recommendations on how to improve the mounting. I want most of the sound to come from the speaker front.

    it is the bass content that suffers most. if your program content has little to no bass then you wont notice much difference in an enclosure mounted speaker vs what you have.

    Ok, there's little Bass content. It's all voice which has been shifted up so the penguin sounds cartoony. But I was wondering how to maximize the sound volume. It currently is amplified by a basic LM386 amplifier circuit and can be heard in a room if you are near the figure. I was trying to improve the quality of sound. I know it's small speaker, but as you can see there's not much room for a larger one.

    Personal there is a huge difference between a box mounted and non box mounted speakers... I would mount it in some kind of encloser or project to better help the quality of sound and the direction.. Also look around with all the fancy design out there .They are all or mostly mounted with some kind of encloser wiether its bass or not ... I have never seen an opened air speaker on both sides ...

    Would the rear be ported at all?

    What you are missing is called the speaker baffle. The main purpose of the baffle and the enclosure is to prevent the backward wave from interfering and cancelling out the forward wave.

    Since you are not interested in good bass response, I wouldn't worry about a port. Your main focus ought to be finding a solid flat panel to mount the speaker that faces the listener.

    Since that speaker does not have mounting holes, you will have to use clamps around the rim of the speaker. They can be as simple as a three screws with washers.

    Change to an 8 Ohm speaker. You will get nearly 2 times the power to the speaker.

    For voice speakers you don't need much of a enclosure. A short tube would be fine (piece of plastic sewer pipe or cardboard mailing tube for example).

    Fix a board (as large as possible with a suitably sized hole or holes cut in it) to those two vertical posts and glue the loudspeaker to it. Or, you could mount it onto one of the existing discs that form the chassis.

    Using the vertical posts is an idea. The mouth opening is straight ahead and parallel to the plane formed by the posts.

    Sounds like a good idea, but to be honest I don't understand your picture?

    You put the speaker inside the ice cream cup and cone facing out.

    Ahhh! Now I get it. The diagram is a cross section of the cup. Thanks, I kept seeing in perspective an object beside a cylinder inside a frame.
