An "audio mailer," including a tape recorder or other sound recording and reproducing device non-removably encased and configured as a mailer, so that a user can conveniently and confidentially send or receive voice or other sound messages through the mail. The mailer may further have a crevice space for an inserted enclosure, such as a letter, document, photograph or other indicia. A customized or commercially available small tape recorder and audiotape sound storage medium may be employed in the preferred embodiment. The audiotape may be either built-in or contained in a removable microcassette. Duplicate removable audiotape microcassettes may be employed to enable a sender to simultaneously record a copy of a mailed audio message and preserve it for future reference. In an alternate embodiment, computer microchip-based sound recording and reproducing technology and storage medium may be employed. The non-removable casing for the recording and playback device and sound storage medium is made of durable cardboard or other durable lightweight material upon which an address and return address may be placed and postage affixed. The recorder's controls are positioned at the top of the casing opening and are fully concealed when the casing is sealed. After initial use, the audio mailer may be either preserved as a keepsake for repeat listening, or reused. The mailer in the preferred embodiment is approximately 31/2'' (width)x71/2'' (legnth)x3/4'' (depth) in dimension, weighing approximately 6 ounces.
