[0002] Apparatuses consistent with the exemplary embodiments relate to a contact !ess und device, such as a horn, that may be configured to output different and/or multiple pitches using a replaceable, or interchangeab e, electronic integrated circuit ("ICp module. In particular, the exemplary embodiments relate to a more energy-efficient and longer-lasting sound device thai utilizes a contacttess horn or sound device m connection wi th a replaceable, or interchangeable, electronic ~\C module to generate sound,
[0003] Apparatuses of the related art include a metal contact, typical ly made out of tungsten, which is magnetically manipulated by an electromagnet in order to cause the diaphragm of a horn to move, thus generating sound in a single pitch. By varying the distance between the contact and the diaphragm, one may manipulate the hor to output different pitches. However, in order to vary the distance between the contact and the diaphragm, and thus achieve these different pitches, the horn's physical structure must be changed, which is a time- consuming, labor-intensive, and costly exercise.
[0004] Furthermore, in the related art, the contact used by the sound device requires a relatively large amount of energy to move the diaphragm doe to the extra weight of the metal contacts required by the related art horn designs. The use of metal contacts in a horn or sound device may also cause sparking around the contact, which increases the risk of fire when the horn is u ed in certain envnvairaents, thus making these related art apparatus s unsuitable tor use in highly iharunable ia uvwwocs mch as m m operations. The fire ns inherent, in rebued ah horn and sound devices also limits the types of materials thai can be used in the construction of the horn to rriaieriais that are nonflammable, thus precluding die use of some lightweight and/or leas expensive alternative materials m the horn design.
[0005] The metal contacts used in related art horn devices also frequently wear our or corrode,, thereby forcing ihe user to replace the contact or, in some eases, the enure horn.
100061 in certain applications, such as in vehicle horns, there is a need for a horn that can produce multiple pitches. Currently, vehicle manufacturers use multiple horns (typically one low note horn and one high note horn) to overcome this limitation. However, the use of multiple horns increases ihe weight of the vehicle, which negatively impacts the fuel efficiency of the vehicle and. increases the energy usage of the vehicle. Indeed, extant vehicle horns consume a large amount of energy, making them undesirable for use; in elecrne and hybrid vehicles.
