Embodiment Construction

[0046] exist figure 1 An embodiment can be seen in FIG. 2 where two converters 10, 20 are provided. The first transducer 10 has a movable diaphragm 12 adapted to be moved to generate sound. Suitable motors or motion generating means to be used are therefore known. Such an electric motor arrangement is positioned within the housing of the converter 10 and is supplied with electrical signals via soldering blocks 18 outside the housing.

[0047] The diaphragm 12 divides the inner space of the transducer 10 into a first cavity 14 and a second cavity 16 . These cavities are generally referred to as the upper and lower cavities of the transducer 10 .

[0048] One of said cavities 14, 16 is connected to the sound outlet 11, which is suitable for conducting sound from the inside of the transducer to the outside. The sound outlet 11 preferably has a spout connected thereto in order to simplify the acoustic connection thereto.

[0049] So far, the transducer 10 may be a standard re...

Abstract

A speaker module for a personal communication device includes two transducers for generating sound on the basis of an electrical signal. One transducer outputs sound to the surroundings from a sound output thereof and the other transducer outputs sound to the surroundings via the first transducer. In this manner, two transducers require only one sound output. The sound from the second transducer may be transmitted through and filtered by an opening in a diaphragm of the first transducer. Filtering elements may be provided between the two transducers.

Description

technical field [0001] The present invention relates to a system comprising two transducer / receivers for outputting sound from a single output, and more particularly to a system in which one transducer outputs sound via the other transducer. Background technique [0002] In today's In-Ear Monitors (IEMs) and similar monitors for personal use (Personal Monitors), more than one receiver is often used to obtain the required frequency range extension performance and maximum sound pressure capability. An example of such a multi-receiver or loudspeaker IEM is disclosed in US Patent Publication 2006 / 0133636, entitled "Sound Tube Tuned Multi-Driver Earpiece". In such receiver / loudspeakers, it is necessary to connect the separate individual sound output outlets or the outlet of each receiver to corresponding appropriately dimensioned sound tubes or sound-conducting components in an acoustically tight manner. The 3300 series receivers, manufactured and sold by SonionNederland B.V., c...
